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.
