Read and understand all of the instructions and safety information in this manual before operating or servicing this tool.

The Greenlee DM-810A, DM-820A, DM-830A, and DML-430A Digital Multimeters are hand-held testing devices with the following measurement capabilities: AC and DC voltage, AC and DC current, frequency, resistance, capacitance, and duty cycle of logic level signals. They also check diodes and verify continuity. All meters feature true RMS AC measurements, a relative zero mode, data hold mode, and an intelligent automatic power off. An optional optically isolated computer interface with software facilitates the recording of readings from the meter to a computer.

Other specialized capabilities and functions common to all meters include:

• Dual display shows two measurements, such as AC voltage and frequency, at the same time.
  Backlighted LCD for reading in dim conditions.
• Beep-Jack™ audible warning alerts the user with a beep and an error message on the LCD if the test lead is plugged into the mA/μA or A input terminal while the selector switch is not in the mA/μA or A position.
• Bar graph display, which responds more quickly than the numeric display — useful for detecting faulty contacts, potentiometer clicks, and signal spikes.

The DM-820A, DM-830A, and DML-430A multimeters have the following additional capabilities: temperature (K-type thermocouples only); conductance; a crest function, which captures voltage or current signal peaks; and a recording function, which stores the maximum, minimum, and difference (maximum-minimum) input readings. The DM-820A and DM-830A record function can also calculate the average reading. These two models also have non-contact and single-probe voltage detection.

The DM-830A and the DML-430A multimeters have an AutoCheck™ function for automatic selection of AC voltage, DC voltage, and resistance with low input impedance to mask "ghost" voltages. Both multimeters feature a T1-T2 function, which can measure and display two temperatures and calculate the difference. They also feature AC + DC true RMS measurement capability. The DM-830A has a dBm function with selectable reference impedances. The DML-430A has the capability to store data.

• For more precision, such as distinguishing between current-carrying and ground wires, connect a test lead to the + input terminal and use it as a probe for direct contact verification of a signal.

DM-830A and DML-430A Only

• Low Impedance AutoCheck™ Mode: In this mode, the meter automatically selects the proper measurement based on the input.

• If there is no input, "Auto" appears on the display.

• If the voltage is above approximately 1.5 volt DC or 3 volt AC up to the rated 1000 volts, voltage is displayed.
• If both AC and DC voltages are present, the larger voltage is displayed.
• If no voltage is present and there is resistance less than 60M , resistance is displayed. If the measured resistance is below the continuity threshold (between 20 and 300 ), then the continuity tone will sound.

This mode features low input impedance to mask stray or "ghost" voltage pickup. The input impedance is approximately 3k at low voltage, increasing to approximately 460k at 1000V .

The symbol "LoZ" indicates that the meter is in a low impedance mode. Do not use the AutoCheckTM mode on circuits that could be damaged or activated by such low input impedance. Instead use the selector to select the high impedance AC or DC volt modes to minimize loading for such circuits.

• Blue Feature Buttons (DML-430A only): Refer to the "Data Storage Function" section for an explanation of these features.

AC Measurement

AC measurements are usually displayed as RMS (root mean square) values. The RMS value is equal to the value of a DC waveform, which would deliver the same power if it replaced the time-varying waveform. Two AC measurement methods are average-responding RMS calibrated and true RMS-reading.

The average-responding RMS calibrated method takes the average value of the input signal after full wave rectification, multiplies it by 1.11, and displays the result. This method is accurate if the input signal is a pure sine wave.

The true RMS-reading method uses internal circuitry to read the true RMS value. This method is accurate, within the specified crest factor limitations, whether the input signal is a pure sine wave, square wave, triangle wave, half wave, or signal with harmonics. The ability to read true RMS provides much more measurement versatility. The Greenlee DM-810A, DM-820A, DM-830A, and DML-430A are true RMS meters.

The Waveforms and Crest Factors table shows some typical AC signals and their RMS values.

Waveforms and Crest Factors

Waveform
RMS Value 100	100 100 100
Average Value 90	100 87 64
Crest Factor* (ξ)	1.414 1 1.73	2

• The crest factor is the ratio of the peak value to the RMS value; it is represented by the Greek letter .

AC + DC True RMS

AC + DC true RMS calculates both of the AC and DC components given by the expression

$$ \sqrt {(A C r m s) ^ {2} + D C ^ {2}} $$

when making measurements and responds accurately to the total effective RMS value regardless of the waveform. Distorted waveforms with the presence of DC components and harmonics may cause:

• Transformers, generators, and motors to overheat
• Circuit breakers to trip prematurely
  Fuses to blow
• Neutrals to overheat due to the triplen harmonics present on the neutral
• Bus bars and electrical panels to vibrate

The DM-830A and DML-430A are AC + DC true RMS meters.

Data Storage Function (DML-430A only)

The DML-430A has data storage and retrieval capability. It can store up to 87,000 measurements in single display mode or 43,000 measurements in dual display mode. The data can later be reviewed on the multimeter's display, or downloaded the data to a computer using the optional interface DMSC-9U.

When in the recording mode, the meter takes a measurement, assigns that measurement to the next available memory location, and repeats the process. This continues until the memory is full or until the user manually stops the recording process.

The time interval between measurements (sampling rate) is selected by the user. A shorter time interval will provide information about short-term fluctuations, whereas a longer time interval will provide information about general trends. The factory setting is the shortest time interval.

The time intervals are as follows: 0.05 seconds (0.1s for single T1/T2, Diode, and Ohms/nS; 0.5s for Hz and Duty Cycle; 2s for Capacitance and dual screen T1/T2 and T1-T2), 0.1s, 0.5s, 1s, 2s, 3s, 4s, 5s, 10s, 15s, 30s, 60s, 120s (two minutes), 180s (three minutes), 300s (5 minutes), and 600s (10 minutes). The minimum total measurement time for the DML-430A is 72 minutes and 30 seconds; the maximum is nearly 20 months.

When the sampling rate is 30s or greater, the meter will go to standby mode between measurements to extend battery life. When the meter is in the standby mode, press SELECT momentarily to view the display.

To set the measurement interval:

Press for 1 second or more and the meter will display the current measurement interval in seconds. Press or to change the measurement interval. Press for 1 second or more to save the new setting.

To start recording data:

Press the button for 1 second or more to start the data logging mode.

"LEFT" displays followed by the number of remaining memory in the logger. The number in the secondary display is the most significant digit, and the numbers in the primary display are the least significant digits of the remaining memory points.

Momentarily press the Yes button to confirm a new logging session without erasing the formerly logged ones (up to 999 sessions can be stored without overwriting previous sessions). Press the Erase button momentarily to erase all of the sessions and start from the first session with full memory.

"Strt" will display on the primary screen and then the logger will start recording. When a sampling speed of 30s or longer is selected, the meter will enter a power down mode after 4.5 minutes. Press the SELECT button momentarily to resume real time display.

Options—duringrecording:

• Press the SELECT button momentarily to toggle the display mode between measuring data and logged data item number. The secondary display contains the most significant number and the primary display contains the least significant numbers of the logged data item number.
• Press the button momentarily to pause/resume logging.

Data Storage Function (DML-430A only) (cont'd)

To stop recording data:

While the meter is logging data, press the button for more than 1 second.

To review stored data:

Press and momentarily to enter Recall mode. The last session number displays for 0.5 seconds and then displays the last logged data item as well the Rnd nunciators.

Options -while reviewing data:

• Press or momentarily to step through the data.
• Press SELECT to toggle between the data and the logged data item number.
• Press and hold or to quickly scan through the data. Tone indicates that the first or last measurement is displayed.
• Press and momentarily to select another session page.

• Noise rejection is the ability to reject unwanted signals, or noise.

• Normal mode voltages are AC signals that can cause inaccurate DC measurements. NMR

(Normal Mode Rejection Ratio) is a measure of the ability to filter out these signals.

Common mode voltages are signals present at the COM and + input terminals, with respect to

ground, that can cause digit rattle or offset in voltage measurements. CMRR (Common Mode

Rejection Ratio) is a measure of the ability to filter out these signals.
