Description
The Greenlee DM-800, DM-810 and DM-820 Digital Multimeters are hand-held testing devices
with the following measurement capabilities: AC and DC voltage, AC and DC current,
temperature (K-type thermocouples only), frequency, resistance and capacitance. They also
check diodes and verify continuity.
Specialized functions and capabilities include:
• MAX/MIN function, which stores the maximum, minimum, and difference
(maximum – minimum)
• Bar graph display, which responds more quickly than the numeric display — useful for
detecting faulty contacts, potentiometer clicks and signal spikes
• Crest capture mode to capture voltage or current signal peaks
• Zoom mode analog pointer, which magnifies the bar graph for higher resolution
