The Greenlee DM-830A (52047807) TRMS 10,000-Count AC/DC Digital Multimeter, 1000V, 10A, is packed with functions you can rely on to get the job done, such as AutoCHECK, NCV EF detection, ghost voltage elimination, 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-830A 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-830A record function can also calculate the average reading. The multimeter also has non-contact and single-probe voltage detection.

The DM-830A multimeter has an AutoCheck function for automatic selection of AC voltage, DC voltage, and resistance with low input impedance to mask "ghost" voltages. The multimeter features a T1-T2 function, which can measure and display two temperatures and calculate the difference. It also features AC + DC true RMS measurement capability. The DM-830A has a dBm function with selectable reference impedances.

The DM-830A 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.
