3. PRODUCT INTRODUCTION

Our counters are a versatile, cost effective solution to a wide range of monitoring and control applications including frequency, rate, total, period, time, phase, position, and flow. Setup can be via front panel pushbuttons or a PC. Selective lockout of front panel keys protects against accidental or unauthorized setup changes and simplifies meter use.

A dual-channel pulse or AC input signal conditioner board accommodates a wide range of applications including rate/frequency, totalizing, timing, phase angle, power factor, and duty cycle. Frequency and rate are determined by taking the inverse of period. Fast read rate is ideal for peak or valley capture and allows quick response for control applications. Adaptive digital filtering provides stable readings and control outputs while responding rapidly to actual changes of the signal. A high stability quartz crystal and digital calibration assure accurate rate and analog measurements.

A process receiver & totalizer signal conditioner board accepts 4-20 mA, 0-1 mA or 0-10V analog signals for display of rate or position. Square root extraction is selectable for use with differential pressure flow transducers.

A quadrature signal conditioner board provides accurate display of position, angle, or rate.

USB, RS232, or RS485 (2-wire half-duplex or 4-wire full-duplex) serial communications options are available with the Modbus protocol or a simpler custom ASCII protocol. Modbus operation includes RTU or ASCII modes, up to 247 digital addresses, and up to 32 devices per RS485 line without a repeater. USB-to-RS485 converter boards allow a meter to be interfaced to a PC and to multiple meters on an RS485 network

Meter programming can be via the meter's front panel or a PC running Windows based Instrument Setup Software. A serial interface option is required.

A standard switching power supply allows the meters to be powered worldwide from 85 to 264 Vac. An optional power supply operates from batteries or low voltage sources, such as 12-32 Vac.

A built-in isolated excitation supply with jumper-selectable 5, 10 or 24 Vdc output levels is standard and can eliminate the need for an external sensor power supply.

A dual or quad relay board is optional for alarm or control. The relays can be Form C 8A mechanical relays or 2 or 4 Form A 130 mA solid state relays. The setpoints can be latching or non-latching, be energized above or below the setpoint, or operate in a fail-safe mode.

A single or dual isolated analog output board is optional. Āith dual outputs, one of the outputs can be assigned to the reading (such a rate), while other reading is assigned a non-displayed item (such as total). The outputs can be 0-20 mA, 4-20 mA, 0-10V, or -10V to +10V.

Operation as a 6-digit serial input meter is achieved with a serial interface and no signal conditioner board, allowing the unit to serve as the remote display of a computer, PLC or other meter. Āith an optional dual or quad relay board, the unit can provide local alarm or On/Off control. Āith an optional analog output board, it can also serve as a local isolated transmitter.

The meter case meets the 1/8 DIN size standard and is sealed to NEMA-4X (IP65) when panel mounted. Mounting is from the front of the panel and requires less than 110 mm behind the panel. All wiring is via removable plugs conforming to IEC950 safety standards. All output options are isolated from meter and power grounds to 250 Vac.

8. FRONT PANEL SETUP KEYS

There are four front panel keys, which change function for the Run Mode and Menu Mode, effectively becoming eight keys. The keys are labeled with alphanumeric captions (MENU, PEAK, RESET, ALARMS) for the Run Mode and with symbols (→ right arrow, ▶ right triangle, ▲up triangle, ← left arrow) for the Menu Mode.

FRONT PANEL LOCKOUT

The Menu Mode will not work with most meters shipped from the factory, since all menu items have been disabled in software and a lockout jumper is in place. This jumper needs to be removed for the Menu Mode to work, and values under Loc 1 through Loc 4 need to be set to "0" via the front panel for these menu items to be available. See Section 9. The paragraphs below assume that all lockout features have been removed.

MENU MODE KEY ACTION

In the Menu Mode, pressing a key momentarily advances to the next item. Holding down the key advances through multiple menu items for fast menu navigation.

KEYS IN RUN MODE

MENU Key. Pressing MENU from the Run Mode enters the Menu Mode. Pressing MENU repeatedly will step the meter through the various menu items (if these have not been locked out) and then back to the Run Mode.

PEAK Key. Pressing PEAK causes the peak value of the input signal to be displayed. The peak display blinks to differentiate it from the normal present value display. Pressing PEAK again will return the display to the present value.

RESET Key. Pressing RESET with PEAK resets peak and valley values. Pressing RESET with ALARMS resets latched alarms. Pressing RESET with MENU performs a meter reset (same as power on). Pressing and releasing RESET without pressing another key changes the displayed item if the mode has multiple items. For Item 1, the V LED is out. For Item 2, the V LED is on. For Item 3, the V LED is flashing.

ALARMS Key. Pressing ALARMS once displays the setpoint for Alarm 1. Pressing it again displays the setpoint for Alarm 2. Pressing it again returns to the present value. After 30 seconds, the meter automatically returns to the present value. Timing is automatically reset whenever the ALARMS key is pressed.

KEYS IN MENU MODE

Right Arrow Key (MENU). Pressing → steps the meter through all menu items that have been enabled and then back to the Run Mode. Aith the dual-channel pulse input signal conditioner board and no option boards, available menu items will be InPut, SEtuP, ConFiG, dSPYno, etc. Actual menu items will vary depending on the Input selection and boards detected in the meter. If a change has been made to a menu item, that change is saved to non-volatile memory when the key is pressed next, and StoreE is displayed briefly.

Right Triangle Key (Digit Select).

• Pressing ▶ from the InPut menu brings up all meter functions available with the meter's signal conditioner. For the dual-channel pulse input signal conditioner, these are rAtE, PEriod, totAL, i Int, Stop t, PHASE, duty C.
• Pressing from most menus selections sequentially selects digit positions 1 - 6, as indicated by a flashing digit: 000000, 000000, 000000, 000000, 000000, 000000.
• Pressing ▶ from dEC.Pt1 brings up a decimal point display of type 11.1111. Pressing ▶ from dEC.Pt2 brings up a decimal point display of type 22.2222.

Up Triangle Key (Value Select).

• Pressing ▲ from a selected meter function, such as rAtE, will select the a specific operating mode within that function, such as _OnLy Always press the MENU key to save your selection. Do not press the ▲key to the right, or your selection will be lost.
• Pressing for a flashing digit position or decimal point position will increment that item. Pressing the MENU key will save any changes.

Left Arrow Key (Reverse Menu). Pressing ← has the same effect as the MENU key, except that menu items are brought up in reverse order.

9. ENABLING & LOCKING OUT MENU ITEMS

For security reasons and ease of operation, any and all menu items may be disabled or "locked out" so that they are no longer directly accessible from the front panel. Each function to be enabled is set to "0" and each function to be disabled is set to "1" in menu items Loc 1-4. These menu items can in turn be locked out by installing an internal hardware jumper. Āith the jumper installed, the operator only has access to enabled menu items. Āith the jumper removed, the operator also has access to the Loc 1-4 menu items.

SETTING HARDWARE LOCKOUT JUMPER

To access the lockout jumper, remove the rear panel per Section 9 and locate jumper "a" in the lower portion of the power supply board next to the input connectors (see figure at right).

SETTING SOFTWARE LOCKOUTS

Ahen setting up the meter, it may be necessary to enable specific menu items by setting the corresponding lockout digit to 0. Be sure to reset the lockout digit to "1" if you do not want the menu item to be changed by an operator.

Loc 1 Loc 2 Loc 3 Loc 4

Press the MENU key until Loc 1, Loc 2, Loc 3 or Loc 4 is displayed, as desired. Note: the lockout jumper must be removed (see above).

111111

Press ▶ to display the lockout status, consisting of 0's and 1's. The left digit will flash. Press ▶ again to step to the next digit, which will flash.

000000 123456

Press ▲ to set the flashing digit to "0" to enable the menu item or to "1" to disable. Press MENU to enter. See the table to the right for list of menu items that can be enabled or disabled.

10. DUAL CHANNEL PULSE OR AC INPUT SIGNAL CONDITIONER

The dual channel signal conditioner board is used for the frequency, rate, period, timing, batch control, phase and duty cycle meter functions. The board needs to be configured via jumpers for the input signal type and level. It is recognized by the meter software, which will bring up the applicable menu items. The dual channel pulse input signal conditioner does not require calibration, since the quartz crystal oscillator used for frequency and timing applications is located on the counter main board.

Jumper Settings for Expected Signal Levels

The jumper settings for Channel A (A2 & A3) and Channel B (B2 & B3) need to be set for the expected signal voltage. This voltage must be outside of the high and low thresholds per the following table, or the meter will not operate properly. The larger the difference between the high and low thresholds, the more immune the meter is to input signal noise.

A3B3	A2B2	Input must be Input must be		A3B3	A2B2	be Input must be		A3B3	A2B2

Jumper Settings for Frequency Response, Bias Resistor, Debounce Time

Pull-up or pull-down resistors are used with open collector devices and dry contact closures to provide input signal bias. They should not be connected for other inputs. Debounce circuitry keeps the meter from counting extra pulses due to contact bounce.

Frequency in Hz is determined by timing an integral number of pulses over a user-specified gate time from 0 to 199.99 sec and taking the inverse of average period. The typical display update rate of the meter is gate time + 1 period + 30 ms Selecting a longer gate time produces a more stable reading as more cycles are averaged, but slows down the update rate. At very low frequencies, the update rate is controlled by the period. A time-out from 0 to 199.99 sec is also selectable. This is the time the meter waits for a signal to start or end a conversion. If the signal is not received before the time-out ends, the meter reads zero. The longer the time-out, the lower the minimum frequency the meter can display.

Aith a scale factor of 1 and multiplier of 1, frequency is displayed in Hz with no decimal point. Applying a multiplier from 1 to 100000 (in decade steps) and setting the decimal point increases resolution (0.1 to 0.00001 Hz). Decreasing the multiplier from 1 to 0.00001 (in decade steps) and setting the decimal point allows display in kHz or MHz. Note that the same 100 kHz frequency can be displayed as 100000 Hz or 100.000 kHz simply by moving the decimal point.

Application: Display rate in GPM to two decimal places from flow meter calibrated to 36.67 pulses/gallon.

Solution: Set Input to "Rate A Only. Under Setup, select "coordinates of 2 p oints" scaling method. Set DecPt1 to two places. Then enter the low input and desired lo reading, and high input and desired high reading, as shown. In this example, we want to display 60.00 (GPM) from an input of 36.67 Hz. Note that the meter's nativ rate measurements are in Hz. There will be 60 times more gallons per minute than per second.

Rate in engineering units is displayed from measured frequency by applying an appropriate scale factor and setting the decimal point. The scale factor consists of a scale value from 0.00000 to 9.99999 (fixed decimal point and settable digits) and a scale multiplier from 0.00001 to 100000 (in decade steps). Åhen using the coordinates of 2 points method to scale the meter, the low input and high input frequencies are entered in Hz.

• RATE A ONLY (A_OnLy) displays rate or frequency for Channel A. The latter utilizes SCALE1, OFFSt1 and dECPt1. Channel B is not used.
• RATE A B (A_b_) displays rate or frequency for Channel A as Item #1 or for Channel B as Item #2. The latter utilizes SCALE2, OFFSt2 and dECPt2.

Application: Display total liquid volume in gallons to two decimal places from 2 pipes dispensing liquids into the same tank. Flow meter A is calibrated to 36.67 pulses/gallon, flow meter B to 58.12 pulses/gallon.

Solution: Arithmetic operations require the Extended counter. Apply flow meter output A output to Channel A, flow meter output B to Channel B. Set Input to "Total A+B." Set Gate Time to 0.01 sec for fast display updates. Select a positive trigger slope for A and B. Set DecPt2, which applies to Grand Total, and DecPt1, which applies to Totals A and B, both to two decimal places. Under Setup, select the coordinates of 2 points scaling method for A and B. To scale A enter 36.67 (pulses) for Hi In1 and 1.00 (gallons) for Hi Rd1. To scale B, enter 58.12 (pulses) for Hi In2 and 1.00 (gallons) for Hi Rd2. The normal display will be Item #1 (Grand Total). Press the key to view Item #2 (Total A) and Item #3 (Total B).

TOTAL A ONLY (A_OnLy) displays the number of pulses applied to Channel A as Item #1. If scientific notation is not selected, overflows beyond 999,999 are recorded in units of 1,000,000 as Item #2. For example, a total of 17,345,676 would be displayed as 345,675 in Item #1 and 17 in Item #2. This capability gives the counter 12-digit capability. Items #1-2 can also be retrieved via serial communications.

• TOTAL A B (A__b__) displays Total A as Item #1 or Total B as Item #2.
• TOTALS A+B, A-B, AxB, A-B, A/B (Extended counter) display arithmetic combinations of Totals A and B as Item #1, Total A as Item #2, and Total B as Item #3.
• TOTAL A-B UD (A-b_Ud) is the same as TOTAL A-B, except that counts are subtracted on an ongoing basis, instead of subtracting totals. This avoids round-off errors with large totals. Overflows are displayed as #2. (See Total A only)
• BURST (_burST) (Extended counter) displays the total number of signal bursts applied to Channel A as Item #1 and signal frequency within a burst as Item #2. Gate time must be greater than the period of the lowest signal frequency and less than the minimum time between bursts. Time-out must be greater than the maximum time between bursts.
• TOTAL A B U/D (A_bU/d) (Extended counter) displays Total A as Item #1, where the up or down count direction is determined by an input on Channel B. If the menu item SLOPE is set to 0 for Channel B, (digit 6), an input level on B below the jumper set Low Threshold B causes the count to go up, and an input level above the jumper set High Threshold causes the count to go down. If SLOPE for Channel B is set to 1, the opposite occurs. The maximum frequency on A that can be counted is 250 kHz, or a minimum of 4 μs between pulses.

- TOTAL A B INHIBIT (A_bInH) (Extended counter) displays Total A as Item #1, where counting may be inhibited by a control input on Channel B. If the menu item SLOPE is set to 0 for Channel B (digit 6), a low input level on B allows counting, and a high input level inhibits counting. If the SLOPE for Channel B is set to 1, the opposite occurs. The maximum frequency on A that can be counted is 1 MHz. Overflows are displayed as #2. (See Total A only)

Application: Fill 55 gallon tanks, measuring flow with a 36.67 pulses/gallon flow meter. Slow down filling at 54 gallons. Cycle batches automatically with 20 sec between cycles. Display batch total & fill rate to 2 places. Track number of batches.

Solution: Use an Extended counter with a dual relay output board. Apply the flow meter signal to Chan nels A & B. Set Input to "Rate Batch." Set Batch to count up Setpoint1. Use Gate Time as delay between batches. Make Item #2 the number of batches. Set Gate Time to 20 sec. S an adaptive moving average filter, which will apply to rate only, not totals. Set DecPt1 and DecPt2 to two decimal places for Items #1 and #3 (Batch Total and Rate). Scale Item #1 (Batch Total) by entering Scale1 of 2.72702 (counts per pulse) and a Setpoint1 of 55.00, which will serve as the batch setpoint in gallons. Scale Item #3 (Rate) using the coordinates of 2 points method so that 36.67 pulses/sec will be displayed as 60.00 GPM. Set Setpoint2 to 54.00 to activate Relay 2 to slow the fil rate at 54.00 gallons.

Batch control (Extended counter) uses the meter with a dual relay controller board to control repetitive fill operations. Relay #1 is used as the batch relay. Relay #2 (or Setpoint #2) can be assigned to another limit, such as pre-warn to slow filling near the setpoint, end-of-process, or rate alarm. The same signal is applied to Channels A and B. Åhen digit 6 of bAtCH (Action after Meter Reset) is set to zero, the following applies:

- In batch control mode without external resets, the meter waits until the RESET key is pushed. It then energizes Relay #1 and displays the changing Batch Total. Āhen the preset value is reached, Relay #1 de-energizes for the duration of the gate time setting. Relay #1 then re-energizes, the Batch Total resets, and the fill cycle repeats.

- In batch control mode with external resets, pushing the RESET key initiates cycling. Grounding an external Gate input for a minimum of 3.33 ms then starts each new fill cycle by energizing Relay #1 and resetting the Batch Total. Gate time is not used.

Three values are tracked and can be separately displayed by pressing the RESET key: Item #1, the Batch Total; Item #2, the Grand Total of all batches or Number of Batches (selectable during setup); and Item #3, the Fill Rate.

• Item #1, Batch Total, is the total for that batch. It may be configured to count up from 0 to a preset, or to count down from a preset to 0. The preset value is placed in SETPT1. SCALE1 is positive whether counting up or down.
• Item #2, Grand Total, is the sum of previous Batch Totals and the current Batch Total. It can overflow to exponential format.
• Item #2 (alternate), Number of Batches, is the current count of batches. SCALE1 does not apply. dECPt1 is set to 1.
• Item #3, Fill Rate, is calculated with a fixed 20 ms (or 1 cycle min) gate time. It may be displayed as Item #3.

PERIOD MODES

• PERIOD A ONLY (A_OnLy) displays period of Channel A as Item #1.
• PERIOD A B (A__b__) displays period of Ch A as Item #1 and of Ch B as Item #2.
- PERIODS A+B, A-B, AxB, A-B, A/B (Extended counter) display arithmetic combinations of Periods A and B as Item #1, Period A as Item #2, and Period B as Item #3.

Application: Measure the closing time of a relay in msec to 0.001 msec resolution.

Solution: To close the relay, apply the same positive voltage to the relay coil and to meter Channel A. ire the relay so that 0V is applied across Channel B when th contacts are closed. Set Input to "Stopwatch A to B." Select a positive trigger slope for A and a negative trigger slope for B. Under Config, set Dis play Mode to sec. Set Gate Time to 0.01 sec. Select the coordinates of 2 points scaling method for Item #1. Set DecPt1 to 3 places. Set Hi In1 to 1.00000 (sec) and Hi Rd1 to 999.999 (msec). Ignore Item #2, which is not used.

• TIME INTERVAL A TO B (A_to_b) measures time between periodic inputs on Channels A and B. Timing starts when a pulse is applied to Channel A (positive edge if slope A is 0, negative edge if slope A is 1), and ends when a pulse is applied to Channel B (positive edge if slope B is 0, negative edge if slope B is 1). Pulse width may be measured by tying inputs A and B together and selecting a positive or negative edge to start (Slope A) and the opposite polarity edge to stop (Slope B). If multiple start and stop pulses occur during the gate time, the displayed value is the average of pulse widths. The value is updated at the end of each gate time. Āith a scale factor of 1, one count is one microsecond.
  • INVERSE TIME INTERVAL (_1/Ab) (Extended counter)

Takes the inverse of time interval for a reading in /second. For example, if the average time interval for object to travel from point A to point B is 5 seconds, the inverse time interval would be 0.2/sec. For the average speed of the objects, simply apply a scale factor equal to the distance separating the two points, such as 7 (inches). Speed would then be displayed as 7 × 0.2 = 1.4 (inches/sec). For a 6-digit reading, apply a scale multiplier of 10,000 and move the decimal point.

• STOPWATCH A TO A (A_to_A) measures time between the same positive (or negative) edge of start and stop pulses applied to Channel A. Single event times may be displayed as Item #1 in decimal seconds, minutes or hours, or in HH:MM:SS clock format. Time is reset to 0 when a new start pulse occurs. Accumulated total time may be displayed as Item #2. Āith a scale factor of 1, one count is one microsecond.
• STOPWATCH A TO B (A_to_B) measures time between a start pulse on Channel A and a stop pulse on Channel B. Timing is the same as for A to A, except that positive or negative edges may be selected separately for Channels A and B. This allows the pulse width measurement of single pulses by tying Channels A and B together. One slope is selected to start timing, and the opposite slope to stop timing.

- INVERSE STOPWATCH TIME A TO A & A TO B (_1/AA & 1/AB) (Extended counter) Takes the inverse of stopwatch time for a reading in /second. For example, if the travel time for an object to travel from point A to point B is 5 seconds, the inverse stopwatch time interval would be 0.2/sec. For the speed of that object, simply multiply by a scale factor equal to the distance separating the two points, such as 7 (inches). Speed would then be displayed as 7 × 0.2 = 1.4 (inches/sec). For a 6-digit reading, apply a scale multiplier of 10,000 and move the decimal point.

DUTY CYCLE MODE (duty\_C) (Extended counter)

Measures ON or OFF period of periodic square waves as a percentage of total period over a gate time which is selectable from 10 ms to 199.99 s. The same signal is applied to Channels A and B. ON or OFF time is measured between positive and negative edges of the signal, with averaging over multiple integral periods over the selected gate time. Apply a scale factor of 1 for readings in percent. Apply a 10 or 100 multiplier and move the decimal point by 1 or 2 positions for 0.1% or 0.01% resolution.

PHASE ANGLE MODE (PHASE) (Extended counter)

Measures the phase relationship in degrees between two signals with the same period over a gate time which is selectable from 10 ms to 199.99 s, with averaging over multiple integral periods over the selected gate time. The two signals are applied to Channels A and B. For best accuracy, both signals should have the same amplitude. The amplitude of sinusoidal signals should be larger than 1V, and the trigger level should be set at 12 mV (no jumper at A3 or B3, jumper a at A2 and B2).

Application: Measure phase angle difference to 0.01° resolution between two AC signals centered around 0°.

Solution: Use an Extended counter, as required for phase angle measurement. Jumper the signal conditioner for maximum sensitivity to catch zero voltage crossings and minimize the effects of amplitude jitter. Apply one AC signal to Channel A and one to Channel B. Set Input to "PHASE +/- 180°." The display will be in degrees. Set a gate time of 0.22 sec for 4 display upda tes per sec. Set both trigger slopes to positive. Set two decimal places. Select the coordinates of 2 points scaling method. Set H In1 to 1.00000 (degrees) and Hi Rd1 to 1.00 (degrees). As an alternative, select the scale and offset scaling method.

Application: Measure "on" period of periodic pulses as a % of total period with .01% resolution over a time interval of 100 sec.

Solution: Duty cycle measurement requires the Extended counter. Apply the same signal to Channels A & B. Set Input to "Duty Cycle (A to B) / A." The native counts will be in percent. For a positive "on" pulse, set trigger slope to positive for A and negative for B. Select the coordinates of 2 points scaling method. Set Hi In to 1.00000 (percent) and Hi Rd1 to 1.00 (percent). As an alternative, select the scale and offset scaling method. Then simply select a scale value of 1.00000 and a multiplier of 100.

1/RATE MODE FOR TIMING (Extended Counter)

An example of 1/Rate is the time it takes an item takes to travel through an oven at a measured rate. Like Rate, 1/Rate can be scaled using Scale1 and Offset1. With no offset and Scale1 set to 1, Rate A for the full analog input range will be displayed as 0-100000, and 1/A will be displayed as 1000000/A. Both the A and 1/A readings are multiplied by Scale1 and offset by Offset1. With Scale1 set to 1, A is displayed as 10000, and 1/A is displayed as 100. With Scale1 set to 2, A is displayed as 20000, and 1/A is displayed as 200. If square root extraction is applied to rate, the rate display A is replaced by , and 1/A is replaced by 1/ . 1/A does not apply to custom curves.

Scaling may also be done by using the coordinates of 2 points method, which automatically calculates scale and offset for the displayed value when the low and high input signals and the corresponding desired low and high displayed values are entered.

11. PROCESS RECEIVER & TOTALIZER SIGNAL CONDITIONER

This signal conditioner board converts 0-1 mA, 4-20 mA or 0-10 V analog process signals to a frequency signal, which is then read by the counter main board and processed mathematically for display of rate, total (time x rate), time based on rate, or batch control.

The board needs to be configured via jumpers for the input signal range. The meter software recognizes the board and brings up the applicable menu items for it.

Please see further manual pages for the following features: relay output, analog output, serial communications, and transducer excitation output.

Application: Display rate in GPM to 3 decimal places from a 4-20 mA flow meter where 4 mA = 0 GPM and 20 mA = 5.820 GPM.

Solution: Set Input to "VF420 A only." Under Setup, select the coordinates of 2 points scaling method. Under Config, select a display of 999999 and filtering. Set the decimal point to 3 places. For scaling, set Hi In1 to 20.0000 and Hi Rd1 to 5.820. Set Gate Time to 0.22 sec, which will provide noise averaging at a display update rate of 4/sec. Also set a 1.6 sec adaptive moving average filter to process the equivalent of 6 readings.

RATE MODE (Basic Counter)

Rate A accepts 0-1 mA, 4-20 mA or 0-10 V analog process signals for a process display scaled to engineering units. Scaling is normally done using the coordinates of 2 points method, where low and high input signals and the corresponding desired low and high displayed values are entered. Scaling can also be done by entering scale and offset directly. Āith Scale1 set to 1 and Offset1 set to 0, the full analog input range is displayed as 0-100000. Measurements are averaged over a gate time, which is programmable from 10 ms to 199.99 sec. Selecting a long gate time provides a slower display update rate but superior

noise filtering. Moving average filtering is also available. Square root extraction is selectable for use with differential pressure flow transducers. Custom curve linearization is available with the Extended counter.

RATE & TOTAL MODE (Basic Counter)

Solution: Set Input to "VF420 A A Total, which displays Rate as Item #1 & Total a Item #2. Under dSPyno, select Item #2 to be displayed after meter reset. Set Gate Time to 0.1 sec to provide fast display updates with noise averaging. Set DecPt1 to 3 places for Rate and DecPt2 to 2 places for Total. Under Setup, select the coordinates of 2 points scaling method for Rate. Set Hi In1 to 20.0000 and Hi Rd1 to 5.820. You will need to use scale & offset to scale Total. Ente 1.66667 for Scale2 and a multiplier of 0.001. That is because totalizing sums rate readings every second. Since our rate is in units per minute, we have to divide by 60, the multiply by 0.1 for two decimal places. You may also enter a Cutoff such as 0.010 GPM, below which zero offset errors and negative values will not be totalized.

Rate A, Total A allows rate to be displayed as Item #1 and total as Item #2. Scale2 and Offset2 apply to total. Total is calculated as the product of displayed rate and time in seconds. Since rate may be displayed in units per second, units per minute, units per hour or other units, the total must be scaled appropriately. If rate is in units per minute, multiply the total by 1/60. This is achieved by setting Scale2 to a scale factor of 1.66666 and a multiplier of 0.01. If rate is in units per hour, multiply the total by 1/3600. This is achieved by setting Scale2 to a scale factor of 2.77778 and a multiplier of 0.0001. If square root extraction or custom curve linearization (available with Extended counter) have been selected, totalizing will be of the linearized rate readings.

BATCH CONTROL MODE (\_bAtCH) (Extended Counter)

Batch control uses the meter with a dual relay controller board to control repetitive fill operations. Relay #1 (or Setpoint #1) is used as the batch relay. Relay #2 (or Setpoint #2) can be assigned to another limit, such as pre-warn to slow filling near the setpoint, end-of-process, or rate alarm.

- In batch control mode the meter displaying “Ready”, the meter waits until the RESET key is pushed, it then energizes Relay #1 and displays the changing Batch Total starting at “Offset2”. Âhen the setpoint 1 value is reached, Relay #1 de-energizes for the duration of the “time out” setting. Relay #1 then re-energizes, the Batch Total resets, and the fill cycle repeats.

- In batch control mode with “external gate”, the meter waits a the end of every cycle until an external gate input is grounded for a minimum of 3.33 ms. This starts a new fill cycle by energizing Relay #1 and resetting the Batch Total. Gate time is not used.

Three values are tracked and can be separately displayed by pressing the RESET key: Item #1, the Batch Total; Item #2, the Grand Total of all batches or Number of Batches (selectable during setup); and Item #3, the Fill Rate.

• Item #1, Batch Total, is the total of input pulses for that batch. It may be configured to count up from 0 to a preset, or to count down from a preset to 0. The preset value is placed in ALARM1. SCALE1 is positive whether counting up or down.
• Item #2, Grand Total, is the sum of previous Batch Totals and the current Batch Total. It can overflow to exponential format.
• Item #2 (alternate), Number of Batches, is the current count of batches. SCALE1 does not apply. dECPt1 is set to 1.
• Item #3, Fill Rate, is calculated with a fixed 20 ms gate time. It may be displayed as Item #3.

Application: Fill 55 gallon tanks. Use a 4-20 mA flow meter where 4 m A = 0 and 20 mA = 39.20 GPM. Slow down filling at 54 gallons. Cycle batches automatically with 20 sec between cycles. Display batch total & fill rate to 2 places. Also track number of batches.

Solution: Use an Extended counter with a dual relay output board. Set Input to "Rate Batch." Set Batch to count up to ALARM1, to use Gate Time as delay between batches and to make Item #2 the number of batches. Set Gate Time to 20 sec. Set DecPt1 and DecPt 2 to two decimal places for Items #1 and #3 (Batch Total and Rate). Scale Item #3 (Rate) using the coordinates of 2 points method so that 20.0000 mA will be displayed as 39.20 GPM. Scale Item #1 (Batch Total) by entering a Scale1 of 1.66667 and a multiplier of 0.01. That is because totalizing sums readings in gallons every second. Since our rate is in GPM, we have to divide by 60. Enter an Offset1 of 55.00to serve as the batch setpoint in gallons. Set Setpoint to 54.00 to activate Relay 2 to slow the rate.

12. QUADRATURE SIGNAL CONDITIONER

Our quadrature signal conditioner board can be used for quadrature position (with Basic or Extended main board) or for quadrature rate (with Extended main board). Two quadrature signals, which are 90° out of phase, are applied to the Channel A and B inputs. Their phase relationship determines whether the count is up (+) or down (-). A zero index signal may be applied to Channel Z as a position reference.

Position in engineering units is determined by adding or subtracting transitions, as determined by the signal phase relationship, applying a programmable scale factor to the total, and adding programmable OFFSET1 to the scaled total. The display update rate is set by a gate time, which is programmed to 10 ms. Āhen the scaled total reaches a programmable Preset, it is reset to OFFSET1.

Rate in engineering units is determined by measuring Rate A and Rate B in transitions per second for Channels A and B, subtracting Rate B from Rate A, and applying a scale factor. Rate is measured over a gate time, which is programmable from 10 ms to 199.99 sec. Since one of the two channels may not be measuring any pulses over the gate time, a timeout from 10 ms to 199.99 sec is also programmable. The meter update rate will never be less than every timeout. Quadrature rate provides a high resolution, high accuracy display.

A zero index function is available on a separate zero index channel to reset the count to the expected count when a zero index pulse is detected. For example, if 3000 counts is expected after three 1000-count revolutions but the current count is 2998 when the zero index pulse is detected, the count is reset to 3000. Since a wide zero index pulse could cause a count discrepancy in the region between transitions, the zero index pulse can be shaped by an AND combination with the A or B channels, as set by jumpers. Please see the diagram at the top of this page, which shows an AND combination of the zero index channel, Channel A and Channel B.

To zero the counts at a hard stop, use function reset.

Please see further manual pages for the following features: relay output, analog output, serial communications, and transducer excitation output.

The quadrature decoder board generates up (+) and down (-) counts that are arithmetically totalized on the main counter board and are then displayed. The decoder board has input circuitry that may be jumpered for single-ended input signals or balanced line driver signals. It accepts normal A & B quadrature signals and, if present, a zero index signal. The A & B signals are 90° out of phase, and their phase relationship determine whether Up counts are added to the total, or Down counts are subtracted from the total.

Since incremental optical encoders may have a different A & B phase relationship to indicate up and down counting, the board has a jumper E7 (BPOL) on the B signal to allow selection of the desired phase. Āith the jumper not installed, Up output pulses are created when the B signal has a positive transition while the A signal is at a positive level (A leads B). Āith the jumper installed, Up output pulses are created when the B signal has a negative transition while the A signal is at a positive level (B leads A). Āith the opposite phase shown, the effect of E7 reverses.

Āith E7 open, counts up.

Āith E7 jumpered, counts down

The board has jumpers that allow counting by 1, 2 or 4 counts per cycle of the A or B signals. The edges that are counted are:

X1 = positive transitions of the A signal.

X2 = positive and negative transitions of the A signal.

X4 = positive and negative transitions of both the A and the B signals.

Digital filtering is provided for the A & B signals to reduce the probability of noise providing false counts.

Some optical encoders create a zero index signal once per revolution that indicates when the encoding wheel is at its zero position. Each time this signal is created, the total count should be a multiple of the number of counts per revolution of the coding wheel. If this feature is enabled in the counter, the counter checks to see if total counts are an exact multiple of the counts per revolution. If so, it does nothing, and if not, it changes the total to the closest exact multiple. The counts per revolution are entered into the counter via the menu item Pulses. From 0 to 59,999 pulses may be entered. If X2 or X4 counting is enabled on the board, the value entered into Pulses should be the counts (or pulses) per revolution of the encoder multiplied by this factor of X2 or X4. If Scale is a factor other than 1, include it as a multiplying factor when determining the value of Pulses to enter. Do not include the value of OFFSET1.

Example:

If the encoder produces 256 cycles per revolution, X2 counting is selected by a jumper on the board and from the front panel Menu of the counter, SCALE1 is set to 3, and OFFSET1 is set to 100, then set PULSES = 256 x 2 x 3 = 1536 from the front panel menu.

The zero index channel has the same digital filtering as the A & B channels. It contains a Polarity jumper that allows selection of either a positive or negative zero index signal. It also contains two Control inputs, C1 and C2 that control the ANDing of the zero index signal with the Channel A and Channel B signals. See “Zero Index Setup” below.

The Item indicator light (center right) may be used to determine the location of the Zero Index. This indicator is lighted while the zero index signal is being received. The zero index signal must be jumpered for the correct polarity. If, during encoder motion, the indicator is on more than it is off, it is likely that the zero index signal is jumpered for the wrong polarity. If so, add a Polarity jumper to switch E8, position C. If it already has a jumper, remove it.

From the menu, a value may be entered for Offset1. As explained below under "Mechanical Zero", OFFSET1 allows a mechanical zero position different from the zero index position. The displayed value is the sum of the following:

1. The total bidirectional counts from the optical encoder since the last counter reset or function reset.
2. The correction factor from the last zero index correction calculation.
3. OFFSET1

Example:

Suppose that the encoder contains 30 pulses per revolution and that X1 counting is used. Further suppose that when the mechanics are at their 0 position, the zero index is at 10, OFFSET 1 = 10, and the counter is reset when the encoder is at the 5 position.

OFFSET	10	10	10	10	10	10	10
	----	----	----	----	----	----	----
Display	0 5	10 20		30 40	50

Once the index point has been passed, the display matches the position. Prior to that, the display is in error.

Ahen the counter is displaying Quadrature Total and the Total is reset using the Reset & Peak buttons (Function Reset), the internal Total is set to zero, but the zero index correction is not affected. This results in a display of the correction value plus OFFSET1. To zero the internal Total and the correction value, the counter must be reset using the Reset & Menu buttons (Meter Reset). This results in a display of OFFSET1.

ZERO INDEX SETUP

The relationship between the zero index correction signal and the Channel A & B signals varies by encoder model and by manufacturer. To accommodate this variation, the Quadra-ture board has control jumpers and selectable outputs that provide ANDing of the zero index signal with all possible combinations of the Channel A & B signals.

Consider a typical encoder model that produces the waveforms shown below. Assume that X4 counting is selected. The count increases or decreases with each A & B transition and remains steady between transitions. The counts shown below the waveforms represent the effect of the zero index correction ZI if no ANDing is used. Note the difference in count in the regions between transitions when counting up and then counting down. The zero index correction is made on the leading edge transition of the zero index signal. Åhen counting down, the leading edge is the trailing edge of the signal shown below because time is increasing from right to left.

It follows that a wide zero index signal causes a discrepancy in the count in the regions between transitions when counting up and counting down. To correct this situation, AND the zero index signal with the A & B channel signals. Assume for this example the zero index is ANDed with the inverse of A (/A) and the inverse of B (/B) to produce ZIY as shown below.

By ANDing the zero index signal with the A & B channels, there is no regional discrepancy between counting up and counting down.

There are 2 control signals, C1 and C2, and 3 outputs, ZI, ZIX and ZIY. These may be jumpered to provide 8 selections of ANDed signals or the zero index signal without ANDing.

The manufacture's data sheet for the optical encoder will show the position and width of the zero index signal with respect to the A channel and B channel signals. Selection of one of the above combinations depends on that relationship and the polarity of the channel A & B signals when the mechanical position is zero. Be sure to take into account the selected phase relationship determined by the presence of or absence of jumper E7-a (BPOL). Jumper E7-a is selected to cause the display to count in the proper direction. If jumper E7 is in place, the channel B signal will have the opposite polarity from the channel B output of the encoder.

MECHANICAL ZERO

By using the Counter's OFFSET1 value, it is possible to place the mechanical zero (zero counter reading) at some point other than the location of the zero index. The following technique describes how to accomplish this.

1. Set the E8 & E10 jumpers as described above to produce the desired Zero Index signal.
2. Set OFFSET1 = 0.
3. Reset the counter (counter reset).
4. Rotate the optical encoder in the positive direction until the reading jumps to zero at the zero index point (Item indicator lights).
5. Reverse the direction of rotation until the desired zero mechanical position is reached.
6. Note the reading and enter that reading into OFFSET1 using the opposite polarity of the display.

7. Reset the counter, and it will display the OFFSET1 value because the internal total counter = 0 and the correction = 0. The position of the encoder when the counter is reset is not critical.

8. Rotate the optical encoder past the zero index point to set the internal correction.

9. Return to the desired zero mechanical position and verify a zero reading.

This completes the procedure. If the encoder is rotated back to mechanical zero, it should read zero. Note: Any time the counter is powered up or reset, the optical encoder should be rotated past the zero index point one time to set the internal correction

If a zero index signal is not available from the encoder, perform the following procedure:

1. Remove any E10 jumpers to eliminate the Zero Index signal.
2. Set OFFSET1 = 0.
3. Adjust the optical encoder to the mechanical zero position and with it in this position, reset the counter.

SETUP SUMMARY

1. Set the input signal jumpers.

A. For single-ended signals such as TTL or CMOS, use jumpers c of E2, E4 and E6 and jumper a of E6. Input signals are applied as follows:

Channel A, P5-1X (AH)

Channel B, P5-3Y (BH)

If an excitation voltage is required, use jumper a of E2 and jumper a of E4.

B. For differential line driver or balanced input signals, use jumper b for E2, E4 and E6. If 120 ohm line termination resistors are desired, place jumpers E1, E3 and E5.
2. Set the correct counting direction by placing or omitting the Channel B polarity jumper E7.
3. Choose X1, X2 or X4 counting and omit a and b of E9 for X1, place a of E9 for X2 or place b of E9 for X4. Determine the scale factor to be used by the counter and set SCALE1 to this value using the counter Menu. Most often it will be set to 1.00000 with a multiplier of 1.
4. If the Zero Index is to be used, do the following:

A. Temporarily place jumper c of E10 and rotate the encoder while watching the Item indicator of the display. If it is OFF most of the time, the Z polarity is correct. If it is ON most of the time, the Z polarity is incorrect, so add jumper c of E8 if it is missing, or remove jumper c of E8 if it is in place.

B. From the manufacturer's specifications for the encoder showing the relationship of the Zero Index signal to the Channel A and Channel B signals, determine from the table above the desired positions of jumpers a and b of E8 and a, b or c of E10. If not used here, remove jumper c of E10 that was placed for the test in A. above.

C. From the manufacture's specifications for the encoder, determine the number of cycles per revolution. Multiply this by 1, 2, or 4 depending on the selection of X1, X2 or X4 counting and multiply that result by the counter scale factor. Put the final result in the counter Menu item, PULSES.

1. Follow the procedure outlined above under the heading MECHANICAL ZERO.

QUADRATURE RATE

Rate and direction may also be displayed using an extended version of the counter. Using quadrature to determine rate not only has the advantage of displaying direction but also eliminates errors due to vibration and jitter that cause erroneous readings in standard rate meters. The meter uses A-B to display quadrature rate. Scale 1 is used to set A to the proper value and scale 2 is set to identical values. Rate (I1) is the difference between Channel A and Channel B.

Solution: Set Input to "Quadrature Rate." Set Gate Time to .22 sec so that the dis play update rate becomes .22 sec +30 ms +1 period. Set Time-out to 1 sec, so that pulse rates under 1 Hz are displayed as 0. Set both DecPt1 and DecPt2 to 3 places. Under Setup, select coordinates of 2 points scaling method. Set both Hi In1 and Hi In2 to 1024.0 (pulses/sec) and both the desired Hi Rd1 and Hi Rd2 to 1.782 (feet/sec). Note: the duplicate entries are required because the quadrature meter subtracts counterclockwise pulses from clockwise pulses.

13. SERIAL INPUT METER / REMOTE DISPLAY OPERATION

Aith a Basic counter main board and a serial interface board, the counter can operate as a 6-digit serial input meter (or remote display) to display serial data received from a computer or PLC, or act as a slave display to another meter, counter or timer with a serial output. A signal conditioner board is not required, but will not interfere with remote display operation if installed.

The serial I/O interface can be provided by any of the following:

• RS232 board: single RJ11 connector for point-to-point communications.
- USB Board: Single standard USB connector for point-to-point communications.
- USB to RS485 board: Single standard USB connector and 1 RJ11 connector for multipoint communications.
- RS485 board: two RJ11 connectors in parallel for multipoint communications, with digital addressing of up to 31 devices. 2-wire (half duplex) or 4-wire (full duplex) connection.
- Modbus RS485 board: two RJ45 connectors in parallel for multipoint communications, with digital addressing of up to 247 devices. Jumper selectable half duplex (2-wire) or full duplex connection..

Slave display operation to the RS232 output of another meter requires that the jumper h be installed on the RS232 board of the slave meter. Also required is a reversing phone cable, where the wire colors of the two connectors are reversed from left to right. For more information, please see the Serial Communications Options Section 16 of this manual or the Jumper Settings sections of the Custom ASCII Protocol Serial Communications Manual.

With an optional dual or quad relay output board (contact or solid state relays), the serial input meter can provide remote alarm or control capability. The meter can be programmed so that the relays respond to the displayed reading or to received control characters. For setup information, please see the Dual & Quad Relay Output Options Section 14 of this manual.

With an optional single or dual analog output board, the serial input meter can provide isolated, scalable 4-20 mA, 0-20 mA, 0-10V or -10 to +10V analog outputs which track the displayed reading, thereby serving as a serial-to-analog converter. For setup information, please see the Analog Output Option Section 15 of this manual.

Front panel setup required for serial input meter (or remote display) operation is shown on the next page. Two items require special explanation:

• The first digit under ConFig item should be set to a value 6 thru C. If no signal conditioner board is detected, the meter defaults to setting 6, where H, L, K commands are enabled. H means display the remote data only. K means that the received value is stored as Item #3, to become the source for alarm comparisons and analog output. L means both H and K. In slave mode, the remote meter can display any item of up to four data Items (or string values), such as the Sum of Rates A & B (Item #1), Rate A (Item #2), or Rate B (Item #3).
• A timeout ti_Out can be set to a value from 10 ms to 199.99 sec. This is how long a serial reading will be displayed in the absence of a new serial input. If timeout is set to 0, the display will persist indefinitely in the absence of a new input.

Additional programmable features of the serial input meter are detailed in the “Command Mode for Remote Display Operation of Counter / Timer” and “Data Formats” sections of the Custom ASCII Protocol Serial Communications Manual. In particular, Mode 12 (hex C), which is invoked by setting the first digit under ConFIG to C, allows extraction of data from an ASCII string that contains multiple data values or non-numeric characters. This mode can accommodate selected Start and Stop characters. Any number of characters between the Start character and the data can be masked OFF. Up to 8 display characters (including sign and decimal point) can be masked ON. Any number of characters between the last displayed character and the Stop character can be masked OFF.

Instrument Setup software is required to set up parameters for the Remote Display in Mode 12 (hex C). This software is downloadable from our website.

14. DUAL & QUAD RELAY OUTPUT OPTIONS

An optional relay board may be installed in the meter main board at plug position P2, adjacent to the power supply board. Four board versions are available: 2 or 4 relays, contact or solid state. Once installed, the relay board is recognized by the meter software or PC-based Instrument Setup software, which will bring up the appropriate menu items for the type of board. These menu items will not be brought up if a relay board is not detected. Menu selections for relays 3 and 4 will

not be brought up if the dual relay board is detected. All relay boards offer a choice of operating modes: normally off or on, latched or non-latched, hysteresis band, deviation band, alarm based on filtered or unfiltered signal, and selectable number of readings in alarm zone for alarm. The source compared to the setpoint may be the displayed item or a non-displayed item. Please see the Glossary at the end of this manual for an explanation of special terms.

16. SERIAL COMMUNICATIONS OPTIONS

A serial communications board may be connected to the meter main board at plug position P13 (middle position). Available boards are RS232, RS485 (with dual RJ11 connectors), RS485 Modbus (with dual RJ45 connectors), USB, USB-to-RS485 converter. The dual connectors of RS485 boards are wired in parallel to allow daisy chaining of addressable meters without use of a hub. Three serial communication protocols are selectable for all serial boards: Custom ASCII, Modbus RTU, and Modbus ASCII.

A USB-to-RS485 converter board allows a meter to be interfaced to a computer and be the device server for a network of up to 31 other meters on an RS485 bus, while itself retaining all capabilities of a meter. The remote meters need to be equipped with our RS485 digital interface board with dual 6-pin RJ11 jacks, not our RS485 digital interface with dual 8-pin RJ45 jacks. The dual 6-pin RJ11 jacks on the RS485 board are wired in parallel to allow multiple meters to be daisy-chained using readily-available 6-wire data cables with no need for hand-wiring or an RS485 hub. The outer two wires are used for ground.

Use 6-wire, straight-through data cables, not 4-wire telephone cables or crossover cables, all the way from the device server to the last device on the RS485 bus. Connect ATX to ATX, BTX to BTX, etc., with no crossover as you go from device to device.

To connect a meter with a USB board to a computer, use a USB cable with Type A and Type B connectors. The computer will display “Found new Hardware” followed by “Welcome to the Found new Hardware Āizard.” Follow the instructions for software installation from a CD. Āhen the installation is complete, use Device Manager to determine the com port. To get to Device Manger, go to the Windows Control Panel, click on System, click on the Hardware tab, then click on Device Manager. Go down the device list and click on Ports (COM & LPT) and USB serial port (com #). Note the com port # for use with communications to your meter, then exit Control Panel. If you later need to change the Com port, right-click on USB serial port (com #), then on Properties, Port settings, and Advanced. Change port to the desired number, click OK, then exit Control Panel.

17. EXCITATION OUTPUT & POWER SUPPLY

Three isolated transducer excitation output levels are available from the power supply board. These are selectable via jumpers b, c, d, e, f in the upper right of the board, as illustrated. In addition, the board provides three jumper positions for special features. The same jumper locations apply to the universal power supply (85-264 Vac or 90-300 Vdc) and to the low voltage power supply (12-32 Vac or 10-48 Vdc).

1. Letters indicate jumper position. Jumpers are installed on pins adjacent to letters.

Excitation output Jumper locations
5 Vdc ±5%, 100 mA max10 Vdc ±5%, 120 mA max24 Vdc ±5%, 50 mA max	b, d, eb, d, fc

Jumper a - Front panel menu lockout, locked when installed. See Section 9.

Jumper g - Provides +5V power output at P1-4 when installed.

Jumper h - Connects "Digital Input B" to P1-4 when installed.

18. INSTRUMENT SETUP VIA PC

Instrument Setup software is a PC program which is much easier to learn than front panel programming. It is of benefit whether or not the meter is connected to a PC. Āith the meter connected to a PC, it allows uploading, editing and downloading of setup data, execution of commands under computer control, listing, plotting and graphing of data, and computer prompted calibration. Āith the meter unconnected to a PC, it provides quick selection of jumper locations and a printable display of menu selections for front panel setup.

SOFTWARE INSTALLATION

Download /S2*.exe onto your PC from the web or the distribution CD. Double-click on the downloaded file to unzip it into a special directory, such as c:\temp. Aithin that directory, double-click on setup.exe, which will install the software on your PC.

PREREQUISITES FOR CONNECTED USE

1) PC with available RS232 com port.
2) Meter to be set up.
3) RS232 board in meter. This board can be used for setup, then be removed.
4) RJ11-to-DB9 RS232 cable to connect meter and PC (see Section 1, Ordering Guide).
5) Instrument Setup software.

RJ11-to-DB9 RS-232 cable

ESTABLISHING COMMUNICATIONS

Connect the meter and PC. Apply power to the meter. Be sure that the meter is in Run Mode, not Setup Mode. To start the software from Windows, click on Start => Programs => IS2 => IS2. Click on RS232 => Establish. The program will temporarily set the selected Com port to the required baud rate, parity, data bits and stop bit. Once communications have been established, click on Main Menu. The software will sense the type of meter and installed boards, but it cannot sense jumpers positions nor set jumpers for you. If the computer is not connected to a meter, select Counter/Timer and Series 2.

SETUP OF CONNECTED METER

A setup file can be retrieved from the meter (Counter => Get Setup), be edited (View => Setup), be saved to disk (File => Save Setup), be retrieved from disk (File => Open Setup), and be downloaded into one or multiple meters (Counter => Put Setup). Downloading of setup files from a PC can be a major time saving when multiple counters have to be set up in the same way.

You will find that Instrument Setup software is very user friendly, with separate tab-selectable windows for Input+Display, Scaling, Filter, Relay Alarms, Communications, Analog Out, and Lockouts. If the required hardware, such as the analog output board, is not sensed, the corresponding tab will be grayed out.

ADDITIONAL FEATURES WHEN CONNECTED

- The Commands pull-down menu allows you to perform Reset functions, to enter numerical values into the meter, and to retrieve numerical values from the meter (Items 1, 2, 3, Peak, Valley).

Plot

Graph

- The Readings pull-down menu provides three formats to display meter data on the PC monitor. Use the Pause and Continue buttons to control the timing of data collection, then press Print for a hardcopy record on your PC printer.

• List presents the latest readings in a 20-row by 10-column table. Press Pause at any time to freeze the display. This is one method to capture peak readings.
• Plot generates a plot of readings vs. time in seconds. It effectively turns the DPM-PC combination into a printing digital oscilloscope.
• Graph generates a histogram, where the horizontal axis is the reading and the vertical axis is the number of occurrences of readings. The display continually resizes itself as the number of readings increases.
• The Jumpers pull-down menu shows board jumper corresponding to specific user selections.
• The Calibration pull-down menu allows easy frequency calibration of the quartz crystal. Simply apply a known calibration frequency up to 1 MHz to Channel A of the dual channel signal conditioner board, type in the frequency value in Hz, and press Enter.

METER SETUP WITH AN UNCONNECTED PC

Instrument Setup software is also of benefit when the PC is not connected to a meter.

Upon launching the software, click on None for Communications, then on Counter/Timer and Series 2. Click on File => Default Setup to retrieve a default setup file from disk, or on File => Open Setup to retrieve a previously saved setup file from disk.

To enter new setup information, click on View => Setup, then make your screen selections as if you were connected to a meter. Tabs will be grayed out if you have not selected the required hardware under the Input+Display tab. Âhen done, press on Main Menu, then on View => Menu. The selections made under Setup will now be shown in the form of the required front panel programming sequence, where each row corresponds to a menu item selected by the → key, and the seven data columns correspond to values entered via the ▶ and ▶ keys.

Click on any step in the sequence to bring up a detailed help window.

Click on Print for a hardcopy, which you can then use as an instruction sheet to program your meter via its front panel.

Click on Main Menu => File => Save Setup As to save your setup to disk and have an electronic record.

19. CUSTOM CURVE LINEARIZATION

Curve.exe is a DOS-based, executable PC program used to set up an Extended meter so that the readings have a user-defined, non-linear relationship with the input signal. For example, it allows a meter to correct for non-linearity of transducers, or to display volume from pressure at the bottom of an irregularly shaped tank. The linearizing parameters are downloaded into non-volatile memory of the meter. The curve fitting algorithm is uses quadratic segments of varying length and curvature, and provides diagnostics to estimate curve fitting errors. The program is self-prompting, avoiding the need for a manual.

PREREQUISITES

1) PC-compatible computer with an available RS232 or USB port.
2) Extended meter*.
3) A serial communication board in the meter. This board can be removed following meter setup.
4) A suitable cable to connect the meter to a PC.
5) Curve.exe software (downloadable at no charge).

RJ11-to-DB9 RS-232 cable

GETTING STARTED

Download curve.exe into the same directory that will contain your data files, such as c:\curves. Set the meter to custom curve linearization. To do so, press the → key to get to ConFG, then set the fifth digit to 1. This digit will only be displayed with an Extended meter*. Set the meter baud rate to 9600. To do so, press the → key to get to SEr 1, then set the entry to 050. Set the meter address to 1. To do so, press the → key to get to SEr 2, then set the entry to 0011. To execute the program from Aïndows, simply double-click on curve.exe. No software installation is required.

OPERATING MODES

The program will prompt you to enter your data in one of four modes. Pressing R (Enter) at any time returns you to the main menu.

1) Text file entry mode, with an X value in one column and a Y value in another. There can be additional columns, which are ignored. The file must have a DOS name of up to 8 characters and the extension .RAÄ. There can be from 5 to 180 rows. X is the input value and should be in the unit of measure for which the meter was set up, such as mV, V, mA or A. Y is the desired corresponding reading and can range from -99999 to 99999 with any decimal point.
2) 2-coordinate keyboard entry mode, where an actual X input signal is applied, and the desired Y reading is entered from the keyboard.
3) 2-coordinate file entry mode, where an actual X input signal is applied, and the desired Y reading is provided from a file.

4) Equation entry mode, where the coefficients of a polynomial Y = K1X^P1 + K2X^P2 + K3^*X^P3 + ... are entered. Up to 20 terms are allowed. And offset can be built into X.

REQUIRED USER INPUTS

• Select CTR
• You will be asked to supply the following:

LOÃ X-COORDINATE VALUE > LOÃ INPUT MEASUREMENT VALUE > HIGH X-COORDINATE VALUE > HIGH INPUT MEASUREMENT VALUE >

This informs the computer of your signal conditioner jumper settings. Enter 0 and 0 for the two LOA values. For HIGH X, enter your signal conditioner jumper range in the same units of measure that you will be using in your *.RAA data input file. Enter 20 for 20 mA or 10 for 10V. For HIGH INPUT MEASUREMENT VALUE, enter 100000,

You will be asked to select the position of the decimal point from 6=X.XXXXX, 5=XX.XXX, 4=XXX.XXX, 3=XXXX.XX, 2=XXXXX.X, 1=XXXXXX (for DPMs, the leading X is a blank). Specify the same position that you specified in the dEc.Pt1 decimal point menu selection.

20. METER CALIBRATION

All ranges of the meter have been digitally calibrated at the factory prior to shipment using computers and calibration equipment certified to NIST standards. If recalibration is required, the meter may be returned to the factory or to any authorized distributor.

For frequency and rate measurements with the dual-channel signal conditioner, a calibration correction to the quartz crystal oscillator is stored in EEPROM on the main board. Calibration constants are also stored in EEPROM in the process receiver & totalizer signal conditioner board and in the analog output board. As a result, these two boards can be mixed and interchanged without requiring recalibration.

For frequency calibration using the dual-channel signal conditioner board, calibration may be performed in the field as follows using the front panel pushbuttons:

1. Set InPut to rAtE and A only.
2. Enter 0 in CALib to set initial correction to 0 PPM.
3. Set SCALE to -9.99999
4. Set OFFSt1 to 999999
5. Apply a 100 kHz reference signal to channel A.
6. Enter the displayed reading in CALib.

For calibration of the process receiver & totalizer signal conditioner board or analog output board, an RS-232 board must be installed in the meter for serial communication with a PC. This board may be removed upon completion of calibration. Calibration software and step-by-step instructions are available from the factory.

22. GLOSSARY OF TERMS

Adaptive filter threshold

A threshold which causes an adaptive moving average filter to be reset to the latest reading when the accumulated difference between individual readings and the filtered reading exceeds that threshold. Adaptive moving average filtering allows a meter to respond rapidly to actual changes in signal while filtering out normal noise. The accumulated difference is also reset to zero when the latest reading has a different polarity than the filtered reading. A low____ adaptive filter threshold is normally selected. A high filter threshold should be selected if the signal has large transients.

Alarm, latched

An alarm which stays actuated until reset. Latched alarms can shut down machinery or a process when an operating limit has been exceeded, or maintain an alarm condition until acknowledged by an operator.

Alarm, non-latched

An alarm which changes state automatically when the reading rises above a specified limit and changes back automatically when the reading falls below a limit.

Autofilter A selectable digital filter mode which automatically selects an appropriate moving average filter time constant from 0.08 sec to 9.6 sec for the encountered noise condition.

Batch control An operating mode of the Extended counter with a relay board, where the counter is used to control repetitive fill operations by counting up from zero to a preset, or counting down from a preset to zero.

Calculated total

While most totals are based on direct pulse counts, certain totals are calculated as running totals based on displayed rate (e.g., Total A, Rate A). The totalizing process assumes that rate is displayed in units per second, such as 300 gallons per second, allowing a scale factor of 1 to be used. If the rate is not in units per second, a different scale factor has to be applied.

Coordinates of 2 points method

A scaling method where the coordinates of 2 points are entered. For a pulse rate input, the first entered point is would be low frequency in Hz and low desired reading. The second entered point would be high frequency in Hz and high desired reading.

Counts The reading displayed on the meter ignoring the decimal point.

Custom ASCII protocol

A simplified, short protocol for use with panel meters, counters and timers. It allows 31 digital addresses. Not an industry-standard protocol, like the more complex Modbus protocol, which is also offered with these instruments.

Custom curve

A user-specified nonlinear relationship between the input signal and displayed reading. Custom curve linearization is available with the Extended counter. One way to supply the data is via a text file with up to 180 data points, which is processed on a PC using furnished software and is then downloaded into EEPROM via serial communications.

Cutoff A programmable threshold in units of flow applicable to Total and Batch Control with the process receiver and totalizer signal conditioner. Flow rates below the cutoff, deemed to be zero offset errors, will not be totalized. Otherwise, small zero offset errors could result in a large error if accumulated over a long time.

Deviation band

A band in counts which controls relay action symmetrically around a setpoint. The relay actuates when the reading falls within the deviation band, and de-actuates when the reading falls outside of this band. A deviation limit (e.g., 50 counts) is set up around both sides of the setpoint to create a deviation band (e.g., 100 counts). Setting up a passband around a setpoint is often used for component testing. Deviation limits are programmed by entering menu item dEUn1b for Al

Duty cycle ON or OFF period of square waves as a percentage of total period over a gate time which is selectable from 10 ms to 199.99 sec. Āith the dual input signal conditioner, the same signal is applied to Channels A and B. Duty cycle can then be read out with resolution to 0.01%.

Extended counter

A counter with an enhanced microcomputer main board that provides added capabilities, such as custom curve linearization of nonlinear inputs and display of rate of change from successive readings.

Frequency Rate in cycles per second or Hertz (Hz). In rate meter mode, a scale factor of 1 and offset of 0 cause a display directly in Hertz with resolution of 1 Hz. To increase or decrease resolution, increase or decrease the scale factor.

Function reset

A rear panel input which resets Peak, Valley and any latched alarms. Latching is achieved by tying the input to logic ground or applying 0V (logic level true). Reset is achieved by opening the input or applying +5V (logic level false).

Gate Time A user-specified time interval from 10 ms to 199.99 sec over which the meter measures frequency. The meter times an integral number of signal periods over the gate time, and then taking the inverse of period. The display update rate of the meter is gate time + 1 period + 30 ms. Selecting a longer gate time

produces a more stable reading as more cycles are averaged, but slows down the update rate. At very low frequencies, the update rate of the meter is controlled by the period. In totalizing mode, the gate is always open, but the gate time setting still determines the update rate of the meter. See also Time-out or Time before zero output.

Hysteresis band

A band in counts which controls relay action symmetrically around a setpoint. The relay closes (or opens) when the reading goes above the setpoint plus one hysteresis limit, and opens (or closes) when the reading falls below the setpoint less one hysteresis limit. A narrow hysteresis band is often used to minimize relay chatter around a setpoint due to electrical noise or signal feedback caused by load switching. A wide hysteresis band can be used for control applications.

Item # Also called Display Item. A numerical value in the meter available for display under control of a front panel key or serial communications. For example, in the A+B totalizer mode, the sum of A+B is Item #1, Total A is Item #2, and Total B is Item #3. Âhen the meter is reset, Item #1 is always displayed. To view another Item, press the RESET key. For Item 1, the yellow View "V" LED is unlit. For Item 2, the "V" LED is lit. For Item 3 the "V" LED flashes.

Menu mode Meter programming mode used for input and range selection, setup, and configuration. Entered into from the Run mode by pressing the MENU key. The Menu mode can be locked out completely by a jumper on the power supply board.

Meter Hold A rear panel input which freezes the meter display and all meter outputs while that input is tied to logic ground by a switch or is held at 0V (logic level true). The meter will resume operation when the input is disconnected or is held at +5V (logic level false).

Moving average filter

A digital filter mode which displays a weighting moving average of readings.

Eight moving average modes are selectable with the following equivalent RC time constants: no filter, 0.1 sec, 0.2 sec, 0.4 sec, 0.8 sec, 1.6 sec, 3.2 sec, 6.4 sec.

Multiplier A constant multiplier from 0.00001 to 100000 (in decade steps) that is combined with a scale factor from 0.00000 to 9.99999 (fixed decimal point and settable digits) to go from frequency in Hz to rate in engineering units such as gallons per minute or from pulse counts to total in engineering units, such as gallons. The combination of a 6-digit scale factor with a multiplier provides more dynamic range with no loss of resolution than could be achieved with a 6-digit scale factor only.

Offset A constant adder to the displayed reading. This may be any value from -999,999 to 999,99. The offset may be used as a preset in the totalize mode, where the total can be counted down from the preset to zero.

Peak display The maximum (or most positive) reading since that value was last reset. Reset can be via the meter front panel, an external input, or a software command. The displayed value can reflect the filtered or unfiltered readings.

Period The time of one complete cycle of the input frequency. A scale factor of 1 and multiplier of 1 produce a display in microseconds.

Phase angle The lead or lag in degrees between two AC signals of the same frequency. Aith the signals applied to Channels A and B of the dual input signal conditioner, phase angle can be displayed from -180° to +180° with resolution to 0.01° .

Pulses Voltage waveshapes with leading and trailing edges that are detected for determination of frequency, period or time. Aith the quadrature signal conditioner, the menu item Pulses is used to set the number of pulses generated by a quadrature encoder for each zero index pulse. This setting is equal to the number of pulses per revolution of the encoder (times 2 or 4 if the count by 2 or 4 is selected on the signal conditioner) times the scale factor.

Process signal

An analog signal whose display requires setup of scale and offset for display in engineering units (such as psi). The process receiver & totalizer signal conditioner accepts 0-1 mA, 4-20 mA or 0-10 V process signals.

Quadrature A quadrature encoder generates 2 signals that are 90° out of phase based on the position of a rotor or linear scale. The phase relationship of these signals depends on the direction of rotation of the encoder. The meter counts up or down depending on the phase. Quadrature is used for very accurate determination of length or position.

Rate Same as frequency, except that a scale factor and multiplier have been applied to convert the reading in Hz to a reading in engineering units, such as RPM.

Remote Display

A display mode which allows the meter to serve as a 6-digit remote display when connected to a computer or other meter via a serial communications link.

Reset Two types of Reset are applicable to counter/timer operation:

• Peak and Valley Reset. Achieved by simultaneously pressing the RESET and PEAK keys.
• Latched Alarm Reset. Achieved by simultaneously pressing the RESET and ALARMS keys.

Resolution A menu item which controls the resolution of arithmetic functions (A+B, A-B, AxB, A/B, A/B-1) of Grand Total in batch mode. It multiplies the displayed value by a factor of 0.00001 to 100,000 in decade steps. The decimal point then has to be moved appropriately.

RS485 half duplex

Serial communications implemented with two wires, allowing data transmission in both directions, but not simultaneously.

RS485 full duplex

Serial communications implemented with four wires, allowing data transmission in two directions simultaneously.

Run Mode The normal operating mode of the meter, where readings are taken, as opposed to the menu mode.

Scale factor A constant multiplier used to go from a raw reading in pulses per second or total pulses to a reading in engineering units. The scale factor consists of a scale value from 0.00000 to 9.99999 (fixed decimal point, settable digits) and a scale multiplier from 0.00001 to 100000 (in decade steps).

Scaling The process of setting scale and offset so that the meter reads properly in engineering units (such as gallons/minute).

Scaling, coordinates of 2 points method

A scaling method where four numbers are entered manually: low input, desired reading at low input; high input, and desired reading at high input. The meter then applies a straight line fit.

Scaling, scale and offset method

A scaling method where scale and offset are entered manually.

Setpoint A value compared to the reading to determine the state of a relay. Term often used interchangeably with “alarm setpoint.”

Stopwatch mode

A timing operating mode for single events. Stopwatch A-to-A measures time between the same positive (or negative) edge of start and stop pulses applied to Channel A. Stopwatch A-to-B measures time between a start pulse on Channel A and a stop pulse on Channel B.

Time interval mode

Returns the average duration of repetitive events over a programmed gate time. Time may be measured from the leading or trailing edge of pulses applied to Channel A to the leading or trailing edge of pulses applied to Channel B.

Time-out (or time before zero output)

The time the meter waits for a signal to start or end a conversion. If pulses are not received before the time-out ends, the meter reads zero. The longer the time-out, the lower the minimum frequency the meter can display. This term is also used for the programmable time that the batch relay stays de-energized at the end of a batch cycle.
