1 Before You Start
1.1 Introduction
Fluke's Hart Metrology Wells (9170, 9171, 9172, and 9173) are designed to be stable heat sources that can be used in a laboratory or field environment. With a calibrated display and an optional built-in reference thermometer input (designated with “-R”), Metrology Wells may also be used as a reference standard.
Metrology Wells feature interchangeable probe sleeves that fit various sized diameter probes.
The Metrology Wells' controller uses a PRT sensor and thermoelectric modules or heaters to achieve stable, uniform temperatures throughout the block.
The LCD display continuously shows many useful operating parameters including the block temperature, block stability, heating and cooling status, and current set-point. The temperature may be easily set with the control buttons to any desired temperature within the calibrator's specified range.
Metrology Wells are designed for laboratory performance that can be used anywhere. With proper use, the instrument will provide continued accurate calibration of temperature sensors and devices. Before use, the user should be familiar with the warnings, cautions, and operating procedures of the calibrator as described in the Getting Started Guide.

GENERAL
DO NOT use this instrument in environments other than those listed in the User's Guide.
Inspect the instrument for damage before each use. DO NOT use the instrument if it appears damaged or operates abnormally.
Follow all safety guidelines listed in this guide.
Calibration equipment should only be used by trained personnel.
If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
Before initial use, or after transport, or after storage in humid or semi-humid environments, or anytime the Metrology Well has not been energized for more than 10 days, the instrument needs to be energized for a “dry-out” period of 2 hours before it can be assumed to meet all of the safety requirements of the IEC 1010-1. If the product is wet
or has been in a wet environment, take necessary measures to remove moisture prior to applying power such as storage in a low humidity temperature chamber operating at 50^ C for 4 hours or more.
DO NOT use this instrument for any application other than calibration work. The instrument was designed for temperature calibration. Any other use of the instrument may cause unknown hazards to the user.
Completely unattended operation is not recommended.
DO NOT place the instrument under a cabinet or other structure. Overhead clearance is required. Always leave enough clearance to allow for safe and easy insertion and removal of probes.
Use of this instrument at HIGH TEMPERATURES for extended periods of time requires caution.
Completely unattended high temperature operation is not recommended due to safety hazards that can arise.
If the instrument is used in a manner not in accordance with the equipment design, the operation of the Metrology Well may be impaired or safety hazards may arise.
This instrument is intended for indoor use only.
BURN HAZARD
Each Metrology Well is equipped with a Block Temperature Indicator (front panel LED HOT indicator – U.S. Patent 7,561,058) even when the instrument is unplugged. When the indicator is flashing, the instrument is not powered and the temperature of the block is above 50^ C. When the indicator is illuminated, always on, the instrument is powered and the block temperature is above 50^ C.
DO NOT turn the instrument upside down with the inserts in place; the inserts will fall out.
DO NOT operate instrument in any orientation other than vertical (block opening face up). Risk of fire or burn hazard may result due to excessive heat build up.
DO NOT operate on a flammable surface or near flammable materials.
DO NOT touch the well access surface of the instrument.
The block vent may be very hot due to the fan blowing across the heater block of the Metrology Well.
The calibration well temperature of the Metrology Well is the same as the actual display temperature, for example, if the instrument is set to 700^ C and the display reads 700^ C, the well is at 700^ C.
The air over the well can reach temperatures greater than 200^ C for high temperature ( 400^ C and higher) Metrology Wells.
Probes and inserts may be hot and should only be inserted and removed from the instrument when the instrument is operating at temperatures below 50^ C.
DO NOT turn off the instrument at temperatures higher than 100^ C. This could create a hazardous situation. Select a set-point less than 100^ C and allow the instrument to cool before turning it off.
The high temperatures present in Metrology Wells designed for operation at 300^ C and higher may result in fires and severe burns if safety precautions are not observed.
ELECTRICAL HAZARD
These guidelines must be followed to ensure that the safety mechanisms in this instrument will operate properly. This instrument must be plugged into a 115 VAC (230 VAC optional), AC only electric outlet. The power cord of the instrument is equipped with a three-pronged grounding plug for your protection against electrical shock hazards. It must be plugged directly into a properly grounded three-prong receptacle. The receptacle must be installed in accordance with local codes and ordinances. Consult a qualified electrician. DO NOT use an extension cord or adapter plug.
If supplied with user accessible fuses, always replace the fuse with one of the same rating, voltage, and type.
Always replace the power cord with an approved cord of the correct rating and type.
HIGH VOLTAGE is used in the operation of this equipment. SEVERE INJURY or DEATH may result if personnel fail to observe safety precautions. Before working inside the equipment, turn power off and disconnect power cord.
1.3.2 Cautions
To avoid possible damage to the instrument, follow these guidelines:
To properly calibrate the Metrology Well, the “Fan Limit” must be set to “Auto.”
DO NOT leave the sleeve(s) in the instrument for prolonged periods. Due to the high operating temperatures of the instrument, the sleeves should be removed after each use and buffed with a Scotch-Brite® pad or emery cloth (see the Maintenance section of the Users Guide).
Always operate this instrument at room temperature between 5^ C and 50^ C ( 41^ F and 122^ F). Allow sufficient air circulation by leaving at least 6 inches (15 cm) of clearance around the instrument. Overhead clearance is required. DO NOT place the instrument under any structure.
DO NOT interchange inserts between Metrology Well models. The inserts provided with the instrument as well as any additional inserts ordered are model specific.
Component lifetime can be shortened by continuous high temperature operation.
DO NOT apply any type of voltage to the switch terminals. Applying a voltage to the terminals may cause damage to the controller.
DO NOT use fluids to clean out the well. Fluids could leak into electronics and damage the instrument.
DO NOT introduce any foreign material into the probe hole of the insert. Fluids, etc. can leak into the instrument causing damage.
DO NOT change the values of the calibration constants from the factory set values. The correct setting of these parameters is important to the safety and proper operation of the calibrator.
DO NOT slam the probe sheath or sleeves into the well. This type of action can cause a shock to the sensor and affect the calibration.
The instrument and any thermometer probes used with it are sensitive instruments that can be easily damaged. Always handle these devices with care. DO NOT allow them to be dropped, struck, stressed, or overheated.
DO NOT operate this instrument in an excessively wet, oily, dusty, or dirty environment. Always keep the well and inserts clean and clear of foreign material.
The Metrology Well is a precision instrument. Although it has been designed for optimum durability and trouble free operation, it must be handled with care. Always carry the instrument in an upright position to prevent the probe sleeves from dropping out. The convenient handle allows for hand carrying the instrument.
If a mains supply power fluctuation occurs, immediately turn off the instrument. Power bumps from brown-outs could damage the instrument. Wait until the power has stabilized before re-energizing the instrument.
The probe and the block may expand at different rates. Allow for probe expansion inside the well as the block heats. Otherwise, the probe may become stuck in the well.
Most probes have handle temperature limits. Be sure the air temperature above the Metrology Well does not exceed the probe handle's temperature limit. If the probe handle limits are exceeded, the probe may be permanently damaged.

3.2 Setup
NOTE: The instrument will not heat, cool, or control until the “CONT ENABLE” parameter is set to “On.” Refer to Set-Point Setup on page 16 to set this parameter.
Place the calibrator on a flat surface with at least 6 inches of free space around the instrument. Overhead clearance is required. DO NOT place under a cabinet or structure.
Plug the Metrology Well power cord into a mains outlet of the proper voltage, frequency, and current capability (see Specifications for power details). Observe that the nominal voltage corresponds to that indicated on the back of the calibrator.
Carefully insert the probe sleeve into the well. Probe sleeves should be of the smallest hole diameter possible still allowing the probe to slide in and out easily. Sleeves of various sizes are available from Fluke Calibration. The well must be clear of any foreign objects, dirt and grit before the sleeve is inserted. The sleeve is inserted with the two small tong holes positioned upward.
Turn on the power to the calibrator by toggling the switch on the power entry module. After a brief self-test, the controller should begin normal operation. The main screen will appear within 30 seconds. If the instrument fails to operate, please check the power connection.
The display will show the well temperature, and wait for user input before heating or cooling to current set-point.
3.3 System Setup
Before using the instrument, the parameters in this section need to be setup (Main Menu: SYSTEM|SETUP MENU).
3.4 Display
Language
Select the preferred language (English, French, or Chinese) using the right/left arrow keys and press “ENTER” to accept the selection.
Decimal
The decimal of the numbers in the instrument can be either a comma or decimal. Select the desired decimal type using the right/left arrow keys and press “ENTER” to accept the selection.
3.4.1 Measure
Stability Limit
NOTE: Metrology Wells should not be expected to operate better than the stability limit specification set forth in the Specifications section of this guide. Therefore, the minimum setting of the stability limit should not be less than the stability specification set forth in the Specifications section.
The stability limit of the instrument is the parameter which allows the instrument to notify the user when it has achieved the stability limit set in this parameter. There are two notifications: visual and audible. The visual notification is always active. When the instrument is operating within the stability limit, the stability parameter on the main screen will remain highlighted as long as the instrument is within the given specification, otherwise the parameter will not be highlighted. The audible, if enabled, alerts the user once per set-point when the instrument achieves the set stability limit. Use the numeric keys to set the desired stability limit and press “ENTER” to accept the new stability limit.
Example:
A specific calibration process requires the instrument be operating within ±0.1^ . “0.1” would be entered into the stability limit parameter. When the instrument is within ±0.1^ , “STAB: X.XXX°C” will be highlighted and the audible alarm (if enabled) will notify the user that the instrument is operating within ±0.1^ . Use the numeric keys to set the desired stability limit and press “ENTER” to accept the new stability limit.
Stability Alarm (STAB ALARM)
The audible alarm described in “Stability Limit” is turned on or off using this parameter. Select either “On” or “Off” using the right/left arrow keys and press “ENTER” to accept the selection.
3.5 Setting the Temperature
The users guide explains in detail how to set the temperature set-point of the calibrator using the front panel keys. The procedure is summarized here.
3.5.1 Set-point Setup
- From the main screen, press "ENTER" once to access the "CONTROL SET POINT" menu.
- Press +/- to set a positive or negative temperature. If the “-” symbol is not present, the temperature is assumed to be positive. Use the number keys to set the desired temperature. Press “ENTER” to set the temperature and continue setting up the set-point information. If the other information in the set-point menu does not need to be edited at this point, press “EXIT” to return to the main screen
NOTE: Each time the instrument is turned off and back on, the “CONT ENABLE” parameter is set to “Off”.
- The “CONT ENABLE” parameter enables or disables active heating or cooling of the instrument. This parameter must be set to “On” for the instrument to heat or cool. Using the right/left arrow keys, select “On” to allow the instrument to heat or cool or select “Off” to disable heating and cooling.
- The scan rate of the instrument can be set from 0.1 to 99°C/min, however the actual scan rate is limited by the natural heating or cooling rate of the instrument. Use the number keys to set the desired scan rate and press “ENTER”.
When the set-point temperature is changed the controller will switch the thermoelectric modules or heater on or off to raise or lower the temperature. The displayed well temperature will gradually change until it reaches the set-point temperature. The well may require 5 to 10 minutes to reach the set-point depending on the span. Another 5 to 10 minutes is required to stabilize with ±0.1^ of the set-point. Ultimate stability may take 15 to 20 minutes more of stabilization time.
3.6 Reference Probe (-R models only)
The reference probe section of the user manual explains in detail how to set up the reference probe of the calibrator using the front panel keys. The procedure is summarized here.
3.6.1 Probe Connection
A PRT is the only type of probe that is supported by the reference thermometer input. The PRT (RTD or SPRT) probe connects to the reference thermometer input using a 5-pin DIN connector. Figure 1 shows how a four-wire probe is wired to the five-pin DIN connector. One pair of wires attaches to pins 1 and 2 and the other pair attaches to pins 4 and 5 (pins 1 and 5 source current and pins 2 and 4 sense the potential). If a shield wire is present it should be connected to pin 3.
Figure 1 Probe connector wiring
A two-wire probe can also be used with the reference thermometer. It is connected by attaching one wire to both pins 1 and 2 of the plug and the other wire to both pins 4 and 5. If a shield wire is present it should be connected to pin 3. Accuracy may be significantly degraded using a two-wire connection because of lead resistance.
3.6.2 Measure Temperature
To make temperature measurements using your probe, the following parameters must be set up:
-
From the main screen, press the "MENU" button. Access the reference probe select menu (REF MENU|SELECT). Select "Probe 1" using the right or left arrow button. Press "ENTER" to accept the probe to be used.
-
To enable "Probe 1," use the ◀ or ▷ button to turn the reference probe "On." Press "ENTER" to accept the selection.
-
Press the "Setup" soft key (Main Menu: REF MENU|SETUP). In the reference probe setup menu, select "Probe 1" and press "ENTER".
-
Select the calibration type for the probe (ITS-90, CVD, or Res) using the ◁ or ▷ keys. Press “ENTER” to accept the calibration type.
-
Use the numeric keys to enter the serial number and calibration coefficients of the probe. Press “ENTER” after each parameter is entered to accept the new parameter value. Calibration coefficients can be found on a report of calibration that was shipped with your probe. If no coefficients can be found, contact the manufacturer or vendor of the probe for assistance. If the probe is out of calibration, Fluke Calibration offers calibration services. Contact an Authorized Service Center for assistance on obtaining a calibration for the probe.
-
After the reference probe has been enabled, the focus of the temperature display can be set. The focus is disabled if the reference probe is disabled. From the reference menu, press the "Focus" soft key (Main Menu: REF MENU|FOCUS). Use the ◀ or ▷ key to select reference focus. Press "ENTER" to accept the selection. The largest temperature on the display will now be the reference temperature.

The Temp Menu (TEMPERATURE MENU) contains all Metrology Well functions related to temperature setup.
5.2.1.1 Set
Figure 8 CONTROL SETPOINT menu
The Set (CONTROL SETPOINT) menu allows the user to change the set-point, enable or disable active heating or cooling, and specify the heating or cooling rate of the instrument. This menu window may be accessed quickly by pressing “ENTER” from the main screen.
SETPOINT
The Setpoint (Set-point) parameter can be set to any value within the range and with resolution as given in the specifications. Be careful not to exceed the safe upper temperature limit of any device inserted into the well. The soft cutout should be properly adjusted to help prevent this occurrence.
CONT ENABLE
NOTE: Each time the instrument is turned off and back on, the "CONT ENABLE" parameter is set to "Off".
The Cont Enable (Control Enable) parameter controls whether the instrument heats or cools. This parameter must be set to "On" for the instrument to heat or cool. Use the right or left arrow keys to select "On" (the instrument heats or cools) or "Off" (disables heating and cooling).
SCAN RATE
The Scan Rate parameter can be set such that when the set-point is changed, the Metrology Well heats or cools at a specified rate (degrees per minute) until it reaches the new set-point.
The scan rate can be set from 0.1 to 500 °C/min (0.2 to 900 °F/min). However, the maximum scan rate is limited by the natural heating or cooling rate of the instrument, which is often less than 100 °C/min, especially when cooling.
The scan rate can be adjusted using the numeric keys. Once the scan rate has been set, press "ENTER" to set the new scan rate.

The Setup (PRESETS SETUP) menu allows the user to set up all eight preset set-points stored in the controller. Setpoints can be quickly selected using the Preset function. Use the Up/Down arrows to scroll through the set-points. The number keys can be used to enter the desired set-point value. Once the desired value has been set, press the "ENTER" key to accept the value. Repeat the previously described procedure until all points are set to the desired values.
5.2.1.4 Cutout
Figure 11 CUTOUT SETTINGS menu
The Cutout (CUTOUT SETTINGS) menu allows the user to set the cutout temperature and to reset the cutout from the display. The cutout temperature is programmable by the operator from the front panel of the controller. As a protection against software or hardware fault or user error, the calibrator is equipped with the adjustable cutout device that shuts off power to the heat source if the well temperature exceeds a set value. This feature protects the instrument and probes from excessive temperatures.
If the cutout is activated because of excessive well temperature, power to the heat source shuts off and the instrument cools. The heat source remains in cutout mode and active heating and cooling is disabled until the user manually resets the cutout. If the over-temperature cutout has been triggered, the instrument displays “CUTOUT” above the duty cycle bar graph, which indicates a cutout condition. The instrument remains in cutout mode until the temperature is reduced and the cutout is reset. The well temperature must drop a few degrees below the cutout set-point before the cutout can be reset.
For safety reasons, the cutout only has one mode — manual reset. Manual reset mode means the cutout must be reset by the operator after the temperature falls below the set-point.
To quickly access the reset cutout function press the "EXIT" key from the main screen.
CUTOUT
The Cutout parameter can be set to any temperature over the range of the instrument. The cutout should be set within 5-10° of the safety limit of the equipment being calibrated or used with the Metrology Well.
RESET CUTOUT
If the Metrology Well exceeds the temperature set in the soft cutout menu or if it exceeds the maximum operating temperature of the instrument, a cutout condition occurs. If this happens, the instrument enters cutout mode and will not actively heat or cool until the user accesses this parameter and selects "Yes".
CUTOUT ALARM
The Cutout Alarm parameter can be set to ON or OFF. If the Cutout Alarm is ON when a cutout condition exists, the alarm will sound every 15 seconds.
5.2.2 Ref Menu (-R instruments only)
Figure 12 REFERENCE MENU
The Ref Menu (REFERENCE MENU) allows all parameters related to the reference thermometer function of the instrument to be accessed. The parameters found in this menu affect the performance, accuracy, and display type of thermometers used.
5.2.2.1 Select
Figure 13 PROBE SELECT menu
The Select menu (PROBE SELECT) allows the user to select and enable the probe that will be used as the reference probe. Parameters for two probes can be stored in the instrument. If the proper probe is not selected, readings acquired from the thermometer will not be accurate. It is important that the proper probe be selected when using the reference thermometer.
PROBE SELECT
The Select parameter can be set to Probe 1 or Probe 2. The probe being used with the instrument should be selected from this menu.
ENABLE
The Enable parameter enables or disables the reference thermometer function of the instrument. This function should be disabled when not in use. In order for the reference probe to function, the reference probe function of the instrument needs to be enabled from this menu. By selecting “On”, the instrument reads the temperature or resistance of the probe connected to the reference input on the front of the instrument.
5.2.2.2 Setup
Figure 14 SETUP PROBE menu
The Setup (SETUP PROBE) menu is used to set up the reference probe(s). The instrument is only compatible with Platinum Resistance Thermometers (PRTs) with ITS-90 or Callendar Van-Dusen calibrations. No other types of coefficients are supported.
The probe serial number and coefficients can be found on the calibration certificate that was shipped with the probe. If the probe requires calibration, contact an Authorized Service Center to inquire about calibration services offered by Fluke Calibration.
While editing the reference probe serial number, there are two soft keys, BACK and DONE. BACK acts as a “backspace” key to allow an incorrect digit or character to be deleted. The DONE key causes the entered serial number to be accepted and returns to the main reference probe editing window.
SELECT
The SELECT parameter is used to choose which probe is to be setup.
TYPE (ITS-90)
The TYPE parameter can be ITS-90 or Callendar Van-Dusen. The ITS-90 option is for PRTs calibrated and characterized using the International Temperature Scale of 1990 (ITS-90) equations. Subranges 4, and 7 through 11 are supported. The parameters that appear when ITS-90 is selected are “Serial” (Serial Number), “RTPW”, “COEF A”, “COEF B”, “COEF C”, “COEF A4”, and “COEF B4”. These should be set with the corresponding values that appear on the calibration certificate of the PRT. The parameter “RTPW” takes the triple point of water resistance, often labeled “R0” or “R(273.16K)” on the certificate. Parameters “COEF A”, “COEF B”, “COEF C” take the a, b and c coefficients where n is a number from 7 to 11. Parameters “COEF A4” and “COEF B4” take the a₄ and b₄ coefficients on the certificate. Any ITS-90 parameter of the instrument that does not have a corresponding coefficient on the PRT’s certificate must be set to 0.
The following table shows which parameter to set for each of the coefficients that may appear on the certificate. The example that follows demonstrates how to set the ITS-90 parameters for certain cases.
NOTE: If the certificate has two sets of coefficients, one set for “zero-power” calibration and one set for 1 mA calibration, use the coefficients for the 1 mA calibration.
Table 4 Matching Certificate Values to 917X ITS-90 Coefficients
| 917X ITS-90 Coefficient Certificate Value |
| COEF A a7, a8, a9, a10, or a11 |
| COEF B b7, b8, b9, or 0 |
| COEF C c7 or 0 |
| COEF A4 a4 |
| COEF B4 b4 |
Example 1:
A PRT was calibrated to ITS-90 and its calibration certificate states values for coefficients Rtpw, a_4 , b_4 , a_8 , and b_8 . Set the instrument's parameters with values from the certificate as follows.
Table 5 Setting Coefficients Rtpw, a8, b8, a4, and b4
| 917X Coefficient Certificate Value |
| RTPW Rtpw |
| COEF A a8 |
| COEF B b8 |
| COEF C 0 |
| COEF A4 a4 |
| COEF B4 b4 |
TYPE (CVD)
The CVD (Callendar-Van Dusen) conversion is for RTD probes that use the Callendar-Van Dusen equation:
$$ r (t [ ^ {\circ} \mathrm{C} ]) = \left{ \begin{array}{l l} R _ {0} \left{1 + \alpha [ t - \delta \frac {t}{1 0 0} \left(\frac {t}{1 0 0} - 1\right) \right} & t \geq 0 \ R _ {0} \left{1 + \alpha \left[ t - \delta \frac {t}{1 0 0} \left(\frac {t}{1 0 0} - 1\right) - \beta \left(\frac {t}{1 0 0} - 1\right) ^ {3} \right] \right} & t < 0 \end{array} \right. $$
The parameters that appear when CVD is selected are “Serial” (Serial Number), “R0”, “ALPHA”, “DELTA” and “BETA”, which can be set by the user. For IEC-751, DIN-
43760 or ASTM E1137 sensors, the coefficients for R0, ALPHA, DELTA, and BETA are 100.0, 0.00385055, 1.499786, and 0.10863 respectively.
Some probes may be provided with A, B, and C coefficients for the Callendar-Van Dusen equation in the following form:
$$ r (t) \mathbb {C} = \left{ \begin{array}{l l} R A (t B t + ^ {2}) & \geq 0 \ R A [ B t C t t + ^ {2} - (1 0 0) ^ {3} ] & < 0 \end{array} \right. $$
The A, B, and C coefficients can be converted to Alpha, Beta and Delta coefficients using the following equation:
$$ \alpha = A + 1 0 0 B \quad \delta = - \frac {1 0 0}{\frac {A}{1 0 0 B} + 1} \quad \beta = - \frac {1 0 ^ {8} C}{A + 1 0 0 B} $$
TYPE (Res)
The Res (Resistance) option displays the resistance, in ohms, of the selected reference probe.

TEST
The TEST parameter requires the user to select the test to be programmed. Select one of the four tests to configure and press “ENTER”.
LOW TEMP
The LOW TEMP parameter is the temperature at which the Metrology Well heats or cools, in order to begin testing if the test is just starting or the temperature at which the instrument begins to heat to start a cycle.
HIGH TEMP
The HIGH TEMP parameter is the temperature during a cycle at which the Metrology Well begins to cool at the rate specified in “Ramp Rate”.
APPROACH
The APPROACH parameter determines when the system scan rate is used and when the switch test ramp rate is used to limit scan rate. During the test, the controller uses the system scan rate until the temperature is within the approach temperature of either the high temp or low temp parameters.
RAMP RATE
The RAMP RATE parameter is the rate at which the instrument heats or cools once the low or high limit is reached. The ramp rate affects the accuracy with which the opening/closing of a thermal switch may be measured. The ramp rate should be selected by the user such that the opening/closing of the switch can accurately be measured.

5.2.3.4.5 Switch wiring and example
The thermal switch or cutout is wired to the calibrator at the two terminals at the front of the Metrology Well calibrator labeled “Switch Test”. The polarity of the switch wires does not matter. Internally, the black terminal connects to ground. The red terminal connects to +5V through a 10 kΩ resistor. The calibrator measures the voltage at the red terminal and interprets +5V as open and 0V as closed.
Example:
A thermal switch opens and closes at about 100 °C , but the accuracy, repeatability, and dead band of the switch need to be verified. The Switch program feature (described in preceding sections) can be used to test the switch. Test results are shown on the main screen during and after the test. To set up the test, do the following:
- Connect the switch wires to the “Switch” terminals on the front of the Metrology Well (as described previously) and place the switch in the well. Match the outside diameter of the switch with a similar sized hole of the Metrology Well insert.
CAUTION: The switch, switch wires, switch components and/or switch accessories can be damaged if the Metrology Well exceeds their temperature limits.
- Set up test "1" at MAIN|PROG MENU|SWITCH MENU|SETUP (see previous sections for more information on switch test setup). Set LOW TEMP to 80 °C, HIGH TEMP to 120 °C, RAMP RATE to 1.0 °C, APPROACH to 5.0 °C, and CYCLES to 3.
NOTE: The LOW TEMP and HIGH TEMP in this example have been set to 100 °C ± 20 °C, but some switches may require a much wider window. The window gives the instrument an approximation of where the switch will open and close. If the window of LOW TEMP and HIGH TEMP is too narrow, the switch test may abort before determining the characteristics of the switch.
NOTE: The APPROACH TEMP, RAMP RATE and CYCLES should be set such that the highest desired accuracy of the switch temperatures is obtained. APPROACH should not be set such that (HIGH TEMP - APPROACH) <= LOW TEMP or “Settings conflict” is displayed when trying to start a switch test and the test will not run.
NOTE: Depending on the mass and/or diameter the switch, there may be a significant lag time in how fast the switch heats up or cools with respect to the block of the Metrology Well. For larger mass and/or diameter switches, a lower RAMP RATE (0.1-0.5 °C) and a higher APPROACH (5-10 °C) can produce better results. More cycles may give a better average of when the switch opens and closes, but a minimum of 2 cycles should be used when running a switch test.
- Select test "1" at MAIN|PROG MENU|SWITCH MENU|SELECT using the arrow keys and press "ENTER".
-
Start the switch test at MAIN|PROG MENU|SWITCH MENU|RUN by selecting Run and pressing "ENTER".
-
Return to the main screen to view the results of the current test by pressing and holding the "EXIT" key (CLOS = switch close temperature, OPEN = switch open temperature) or at MAIN|PROG MENU|SWITCH MENU|VIEW (CLOSE = switch close temperature, OPEN = switch open temperature, BAND = difference between open and close temperature).
-
Once the test is finished, the data can be recorded, or the test can be run again by repeating the steps above.

5.2.4.1.2 Meas
Figure 29 MEASUREMENT SETTINGS menu
The Meas (MEASUREMENT SETTINGS) menu is used to set the stability limit and alarm.
STAB LIMIT
NOTE: The Metrology Well should not be expected to operate better than the stability specification set forth in the Specifications section of this guide.
Therefore, the minimum setting of the stability limit should not be less than the stability specification.
The STAB LIMIT parameter allows the instrument to notify the user when it has achieved the stability limit set in this parameter. There are two notifications: visual and audible. The visual notification is always active. When the instrument is operating
within the stability limit, the stability parameter on the main screen remains highlighted once the instrument is within the given specification, otherwise the parameter is not be highlighted. The audible, if enabled, alerts the user once per set-point when the instrument achieves the set stability limit. Use the numeric keys to set the desired stability limit and press “ENTER” to accept the new stability limit.
Example:
A specific calibration process requires the instrument to operate within ±0.1^ . “0.1” would be entered into the stability limit parameter. When the instrument’s stability is within ±0.1^ , “STAB: X.XXX°C” is be highlighted and the audible alarm (if enabled) notifies the user that the instrument is operating within ±0.1^ . Use the numeric keys to set the desired stability limit and press “ENTER” to accept the new stability limit.
STAB ALARM
The audible alarm described in STAB LIMIT is turned on or off using the STAB ALARM parameter. Select the either "On" or "Off" using the ◀ or ▷ arrow keys and press "ENTER" to accept the selection.
5.2.4.1.3 Oper
Figure 30 OPERATION SETTINGS menu
The Oper (OPERATION SETTINGS) menu allows the user to set up the limit for the maximum speed of the fan. The FAN LIMIT parameter can be set to Auto, Medium or Low. The Auto setting allows the instrument to operate at maximum efficiency for the chosen set-point. The instrument may be noisier as the fan moves at different speeds through the temperature range improving the performance. At low temperature settings, the fan operates at its fastest speed. At high temperatures, the fan operates at a lower speed.
NOTE: The Low setting is quieter, but decreases scan rate, reduces low temperature performance and may prevent the instrument from fully meeting all specifications. The Medium setting falls in the middle of Auto and Low. The Medium setting does not allow the fan to operate at its fast speed, but does allow it to operate at slower speed when applicable.
5.2.4.1.4 Comm
Figure 31 COMMUNICATION SETUP menu
The Comm (COMMUNICATION SETUP) menu contains the serial interface parameters. The parameters in the menu are — PORT, BAUD rate, LF, ECHO, SERIAL PERIOD and PRINT.

BAUD
The BAUD parameter determines the serial communications transmission rate or baud rate.
BAUD may be programmed to 1200, 2400, 4800, 9600, 19200, or 38400 baud.
LF
The LF (Line Feed) parameter enables (On) or disables (Off) transmission of a line feed character (LF, ASCII 10) after transmission of any carriage-return. The “LF”
default setting is on. The line feed parameter can be turned on or off as needed by the user.
ECHO
The ECHO parameter mode may be set to "On" or "Off". With echo "On", any commands received by the thermometer via the serial interface are immediately echoed or transmitted back to the device of origin. With echo "Off", the commands are executed but not echoed. The default setting is "On". The mode may be changed using the left or right arrow keys and pressing "ENTER".
SER PER
The SER PER (Serial Period) parameter is the interval at which data is transmitted by the instrument to a computer through the serial interface. The serial period is the time period, in seconds, between temperature measurements transmitted from the serial interface. For example, if the sample rate is set to 5, the instrument transmits the current temperature measurement approximately every 5 seconds.
The PRINT parameter enables or disables printing the control temperature and power through the serial port.
NOTE: If PRINT is set to "Off", samples are not transmitted automatically through the serial interface.

6 Digital communication interface
The Metrology Well is capable of communicating with and being controlled by other equipment through the RS-232 digital interface.
With a digital interface the instrument may be connected to a computer or other equipment. This allows the user to input the set-point temperature, monitor the temperature, and access any of the other controller functions, all using remote communications equipment. The RS-232 serial interface allows serial digital communications over fairly long distances. With the serial interface, the user may access any of the functions, parameters and settings discussed in this section.
6.1 Wiring
The serial communications cable attaches to the instrument through the DB-9 connector at the back of the instrument. Figure 39, on this page shows the pin-out of this connector and suggested cable wiring. To eliminate noise, the serial cable should be shielded with low resistance between the connector (DB9) and the shield.

6.1.1 Setup
Before operation the serial interface must first be set up by programming the BAUD rate and other configuration parameters. These parameters are programmed within the communications menu. The serial interface parameters can be accessed from the main menu by MENU|SYSTEM MENU|SETUP MENU|COMM. Refer to “Comm” in the Controller Operation section for more information on the serial interface parameters.
6.1.2 Serial Operation
Once the cable has been attached and the interface set up properly, the controller immediately begins transmitting temperature readings at the programmed rate. The serial communications uses 8 data bits, one stop bit, and no parity. The set-point and other commands may be sent via the serial interface to set the temperature set-point and view or program the various parameters. The interface commands are discussed in the “Digital Interface” section.
6.2 Command Syntax
Metrology Wells accept commands for setting parameters, executing functions or responding with requested data. These commands are in the form of strings of ASCII-encoded characters. As far as possible, the Metrology Well command syntax conforms to SCPI-1994. One notable exception is that compound commands are not allowed as explained below.
Commands consist of a command header and, if necessary, parameter data. All commands must be terminated with either a carriage return (ASCII 0D hex or 13 decimal) or new line character (ASCII 0A hex or 10 decimal).
Command headers consist of one or more mnemonics separated by colons (:). Mnemonics may use letter characters, the underscore character ( ), and possibly numeric digits as well. Commands are not case sensitive. Mnemonics often have alternate forms. Most mnemonics have a long form that is more readable and a short form consisting of three or four characters that is more efficient.
A mnemonic may end with a numeric suffix that specifies one of a set of independent function blocks such as input channel data paths. If a numeric suffix is omitted when a particular block must be specified, an error is generated (“Header suffix out of range”).
Query commands are commands that request data in response. Query commands have a question mark (?) immediately following the command header. Responses to query commands are generated immediately and placed in the output buffer. Responses are then transmitted automatically over the RS-232 port. Responses are lost if not read before the next command is received.
Some commands require parameter data to specify values for one or more parameters. The command header is separated from the parameter data by a space (ASCII 20 hex or 32 decimal). Multiple parameters are separated by a comma(,).
Metrology Wells do not allow compound commands (multiple commands per line separated with semicolons). All commands are sequential. The execution of each command is completed before subsequent commands are processed.
6.3 Commands by Function or Group
In this section, the commands are arranged into the following groups:
Calibration Commands - commands for Metrology Well calibration parameters.
Main Screen Commands – commands for parameters displayed on the main screen.
Program Commands – commands for program setup and status.
Reference Commands - commands for accessing reference thermometer parameters.
Setup Commands – commands for setting up communication, display, measure, and operation parameters.
Switch Commands – commands for switch testing.
System Commands - commands to report and change the status of the instrument.
Temperature Commands - commands for control temperature and cutout functions.

6.4 Serial Commands - Alphabetic Listing
Each command description provides the structure (long and short format), a description of the command purpose, a command example, an example of what the command returns (as applicable to query commands), and notes specific to the command. The following apply to each group of commands:
- Numeric data, specified by the mnemonic,
, uses ASCII characters to represent numbers. Numbers may contain a plus or minus ('+' or '-'') sign, decimal point (‘.’), and exponent ('E' or 'e') with its sign. If a fractional component is received when only an integer is required, the number is rounded to the nearest integer without any resulting error message. The mnemonics DEF, MIN, and MAX are often acceptable for the default, minimum, and maximum value respectively. Unit suffixes, such as V or OHM, can be appended to numeric parameters and are accepted without error but ignored. - Unrecognized commands or commands with incorrect syntax or invalid parameters generate error messages in the error queue.
- Upper case letters designate syntax that is required when issuing the command. Lower case letters are optional and may be omitted.
• indicates a required parameter.
• [] indicates optional parameters. - () indicates a group of parameters that must be used together.
- For query commands, specifying the MIN, MAX, or DEF parameter causes the instrument to respond with the minimum, maximum, or default setting respectively.
- For set commands, specifying the MIN, MAX, or DEF parameters causes the instrument to use the minimum, maximum, or default setting respectively.
- ‘|’ indicates alternate parameter values.
•indicates a number is required. indicates numeric value is required. indicates a program number (SEQ or SWIT ) is required. indicates a Boolean value (0 or 1) is required.

7 Calibration of your Metrology Well
7.1 General
NOTE: For assistance with the process or any questions regarding the calibration of the Metrology Well, contact an Authorized Service Center.
7.2 Terminology
If the External Reference option was purchased, the Metrology Well actually consists of two separate instruments combined. When calibrating the Metrology Well, two separate calibrations will be conducted. For convenience in terminology, the External Reference is referred to as the Readout. The dry-block calibrator is referred to as the Heat Source. The Readout and Heat Source combine make up the Metrology Well.
The Axial Uniformity is referred to as the Vertical Gradient.
Resistance Certification is the process utilized to take As Found or As Left Data. The process does not change any calibration parameters. The process records the state of the instrument prior to adjusting the calibration parameters, As Found Data; or it verifies the state of the instrument after adjusting the calibration parameters, As Left Data.
NOTE: The Measuring and Test Equipment (M&TE) is referred to as the Unit Under Test (UUT).
7.3 Fundamentals
It is assumed that the technician is familiar with the Metrology Well Technical Guide.
It is assumed that the calibration will only be performed by trained personnel.
Readout calibration or Heat Source calibration may be optional depending on UUT configuration and customer requirement.
Environmental Conditions
Temperature range: 23^ ± 4^
Ambient relative humidity: below 60%
NOTE: Do not use an aluminum insert in the hot Metrology Wells (9172 or 9173). In the 9172, the insert will become stuck. In the 9173, there is a potential to melt the insert. Inserts purchased from Fluke are engraved with the corresponding model.

NOTE: Access to the calibration parameters needs to be enabled using the Serial Command SYST:PASS:CEN followed by a space and the correct password.
NOTE: Calibration requires adjustment of the REF1, REF2, and REF3 parameters at 0, 100 and 400Ω respectively. The order in which the adjustments are performed is important. The adjustment of the REF3 parameter must be performed last as the adjustments of REF1 and REF2 affect the measurement at 400Ω but REF3 does not affect the measurements at 0 or 100Ω. Refer to Table.
a. As noted above the order in which the adjustments are performed is critical.
b. The calibration parameters are accessed from the front panel by selecting MENU|SYSTEM|CAL MENU. Enter the correct password to access the parameters. The parameters may also be accessed through the RS232 interface using the commands shown in Table 12.
Table 12 Serial command, adjustment parameters
| Command Adjustment Parameter |
| SENS:CAL:PAR1REF1 |
| SENS:CAL:PAR2REF2 |
| SENS:CAL:PAR3REF3 |
c. During the adjustment, collect no less than 40 and no more than 400 readings and compute the average.
d. Connect the 0 resistor to the input and measure its resistance. Note the difference between 0 and the measured resistance. The new REF 1 is given by subtracting the difference from the current REF 1. Adjust REF 1 as needed.
e. Repeat for the other resistors as noted in Table 11.
f. Verify the accuracy by performing Manual Resistance Certification, using Table 9, One-year accuracy specifications, on page 97, limits of error.

8 Maintenance
The Metrology Well has been designed with the utmost care. Ease of operation and simplicity of maintenance have been a central theme in the product development. With proper care, the instrument should require very little maintenance. Avoid operating the instrument in an oily, wet, dirty, or dusty environment. Operating the instrument in a draft-free environment facilitates improved performance of the instrument.
- If the outside of the instrument becomes soiled, it may be wiped clean with a damp cloth and mild detergent. Do not use harsh chemicals on the surface which may damage the paint or plastic.
- It is important to keep the well of the calibrator clean and clear of any foreign matter. DO NOT use fluid to clean out the well.
- The instrument should be handled with care. Avoid knocking or dropping the calibrator.
- The removable sleeves can become covered with dust and carbon material. If the buildup becomes too thick, it could cause the sleeves to become jammed in the wells. Avoid this build up by periodically buffing the sleeves clean.
- If a sleeve should be dropped, examine the sleeve for deformities before inserting it in the well. If there is any chance of jamming the sleeve in the well, file or grind off the protuberance.
- DO NOT allow the probe stems to drop into the well or harshly impact the well bottom. This type of action can cause a shock to the sensor.
- If a hazardous material is spilled on or inside the instrument, the user is responsible for taking the appropriate decontamination steps as outlined by the national safety council with respect to the material.
- If the mains supply cord becomes damaged, replace it with a cord of the appropriate gauge wire for the current of the instrument. If there are any questions, contact an Authorized Service Center for more information.
- Before using any cleaning or decontamination method, other than those recommended by Fluke, users should check with an Authorized Service Center to insure the proposed method will not damage the equipment.
- If the instrument is used in a manner not in accordance with the equipment design, the operation of the instrument may be impaired or safety hazards may arise.
- The over-temperature cutout should be checked every 6 months to see that it is working properly. In order to check the user selected cutout, follow the controller directions for setting the cutout. Set the instrument temperature higher than the cutout. Check to see if the display shows cutout and the temperature is decreasing.
8.1 Regular metrology well performance analysis
For optimum performance and lowest possible uncertainty budgets, use the guidelines set forth below.
Accuracy drift
The display temperature of the Metrology Well will drift over time. This is due to a variety of factors affecting the temperature control PRT. Any PRT is subject to changes depending on how it is used and the environment it is used in. This is no different for any PRT in a calibration application. In addition, manufacturing variables in the sensing element itself can result in greater or lesser impact from use and environment. Oxidation and contamination from the sensor's environment will create changes requiring new calibration constants depending on the temperature range and normal operation of the instrument. Oxidation and contamination are generally not factors when Metrology Wells are used exclusively below 200°C. Oxidation can form in the body of the PRT platinum sensor wire in the range of 300°C to 500°C. Contamination is primarily a problem following prolonged use above 500°C. Additionally, vibration from handling or transportation will strain the delicate PRT element, changing its resistance. Some of this strain may come out by annealing at a slightly higher temperature than the instrument is typically used at. It is recommended to avoid unnecessary temperature cycling. Cycling the temperature up and down between minimum and maximum temperatures excessively may also cause strain on the PRT element.
Effects from control sensor drift may be avoided by using an external temperature reference. In the case that the calibration of the display value is required, a program of monitoring and recalibration must be implemented, just as with any calibration standard. Regularly check the accuracy of the Metrology Well with an adequate temperature reference and keep records as a part of your instrument maintenance routine. When the accuracy drifts to a point where it is no longer acceptable, then have the instrument recalibrated. Your records will provide data for determining a calibration interval appropriate for your history of use and accuracy requirements.
Stability
The stability specification of the Metrology Well was determined under laboratory conditions of steady ambient temperature and air flow. While this instrument has been designed to minimize ambient effects, they will still have some effect. For the best results, avoid quickly-changing ambient temperatures and drafty conditions.
Axial Uniformity
Metrology well axial uniformity should be checked periodically. Use the process outlined in EA 10/13 or a similar process. If, due to a drift in the differential thermocouples, the axial uniformity has changed outside the limits set by the user's uncertainty budget, adjust the axial gradient as outlined in the Metrology Well Calibration section of this guide and recalibrate the Metrology Well.
9 Troubleshooting
This section contains information on troubleshooting.
In the event that the Metrology Well appears to function abnormally, this section may help to find and solve the problem. Several possible problem conditions are described along with likely causes and solutions. If a problem arises, please read this section carefully and attempt to understand and solve the problem. If the Metrology Well seems faulty or the problem cannot otherwise be solved, contact an Authorized Service Center for assistance. Be sure to have the instrument model number, serial number, and voltage available.
9.1 Troubleshooting
| Problem Causes and Solutions | |
| The display is blank Check the fuses. If a fuse blows, it may be due to a power surge or a component failure. Replace the fuse once. DO NOT replace the fuse with one of a higher current rating. Always replace the fuse with one of the same rating, voltage, and type. If the fuse blows a second time, it is likely caused by failure of a component part.Power Cord. Check that the power cord is plugged in and connected to the instrument.AC Mains Power. Insure the circuit supplying power to the instrument is on. | |
| The instrument heats slowly | Scan/Scan Rate. Check the Scan and Scan Rate settings. The Scan may be on with the Scan Rate set low. |
| If the display shows an abnormal temperature | The sensor is disconnected, open or shorted. Please contact a Service Center for further instructions. |
| If the display shows cutout | Cutout. The software cutout is set too low. Check and adjust the cutout setting by pressing “Exit” from the main screen. |
| Temperature readout is not the actual temperature of the well OR Incorrect temperature reading | Noise. With the instrument stable, slowly rotate the entire instrument. If no change occurs, the instrument may need to be calibrated. Contact an Authorized Service Center for calibration service. If the display changes more than twice the normal display deviation, another unit in the area could be emitting RF energy. Move the instrument to a different location and rotate it again. If the temperature is correct in this new area or deviates differently than the first area, RF energy is present in the room. If you have to perform the test in the effected area, use the comparison test to eliminate any possible errors.Operating Parameters. Insure that all operating parameters for the Metrology Well, reference thermometer, and/or probe parameters match the Report of Calibration that was sent with the instrument and/or probe. |
