Page 2: Purpose Of This Manual
Description 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. -
Page 3: Important Safety Information
Electric shock hazard: Contact with live circuits could result in severe injury or death. All specifications are nominal and may change as design improvements occur. Greenlee Textron Inc. shall not be liable for damages resulting from misapplication or misuse of its products. - Page 4 Important Safety Information Electric shock and fire hazard: • Do not expose this unit to rain or moisture. • Do not use the unit if it is wet or damaged. • Only use the test leads provided with the equipment or UL Listed Probe Assembly with same rating or better.
- Page 5 DM-810A • DM-820A • DM-830A • DML-430A Important Safety Information Electric shock hazard: • Unless measuring voltage, current, or frequency, shut off and lock out power. Make sure that all capacitors are discharged. Voltage must not be present. • Set the selector and connect the test leads so that they correspond to the intended measurement. Incorrect settings or connections can result in a blown fuse.

Page 8: Using The Features
Using the Features All Models • Dual Digital Display: These meters can display two measurements, such as AC voltage and frequency, at the same time. Display combinations are shown using large symbols to indicate the measurement on the primary display and small, raised symbols to indicate the measurement on the secondary display. - Page 9 DM-810A • DM-820A • DM-830A • DML-430A Using the Features (cont’d) Note: When using the REC function, pressing RANGE will cause the meter to exit this mode. DM-820A and DM-830A Only • EF: Set the meter to any current or voltage function. Press and hold until the meter displays “EF” to detect the electric field that surrounds current-carrying conductors.
- Page 10 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 wave- form. 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.
- Page 11 DM-810A • DM-820A • DM-830A • DML-430A 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.
- Page 12 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 p and q 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 annunciators.
