Item_number: GRDM-820A Categories: , , , Tags: ,

The Greenlee DM-820A 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 multimeters 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 multimeter to a computer.
