The Greenlee DM-510A (52047803) True-RMS 6000-Count AC/DC Digital Multimeter, 1000V, 8A, is designed to provide all of the critical day-to-day features of a handheld multimeter in a compact, ergonomic design. Users can rely on the multimeter for CAT IV 300V, CAT III 600V and CAT II 1000V applications and take advantage of AutoCHECK, EF-Detection, audible and visible alerts and a backlit LCD display.

Backed by Greenlee's lifetime limited warranty, the DM-510A multimeter offers superior value to professional electricians. The handheld meter is equipped with the following measurement capabilities: AC and DC voltage, AC and DC current, capacitance, temperature (K-type thermocouples only), frequency, and resistance. It also checks diodes and verifies continuity. 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.

The DM-510A multimeter has an AutoCheck function for automatic selection of AC voltage, DC voltage, and resistance with low input impedance to mask "ghost" voltages. The DM-510A also has a crest function, which captures voltage or current signal peaks, as well as a recording function, which stores the maximum and minimum input readings. The DM-510A is a true RMS meter.
