Greenlee, 08745, DM-820A RMS Digital Multimeter with Auto-Check Function, Bead Temperature Probe
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.
