The Greenlee DM-820A (52047806) True-RMS 10,000-Count AC/DC Digital Multimeter, 1000V, 10A, is packed with functions you can rely on to get the job done, such as NCV EF detection, audible and visible alerts, and a high resolution display. The hand-held testing device is equipped with the following measurement capabilities: AC and DC voltage, AC and DC current, frequency, resistance, temperature, conductance, capacitance, and duty cycle of logic level signals. It also checks diodes and verifies continuity. The meter features true RMS AC measurements, a relative zero mode, data hold mode, and an intelligent automatic power off.

The DM-820A multimeter also features 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 record function can also calculate the average reading. The multimeter also has non-contact and single-probe voltage detection.

The DM-820A multimeter includes a durable carrying case for meter storage and protection. An optional optically isolated computer interface with software (sold separately) facilitates the recording of readings from the meter to a computer, allowing for the tracking, organizing and storing of jobsite data.
