Description
The Greenlee DM-500 and DM-510 Digital Multimeters are hand-held testing devices with the following measurementcapabilities: 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: • Harmonics function, for detecting the presence of disruptive harmonics • Industrial Process Control Loop Current function, which allows checking the output from a standard 4 mA to20 mA control loop • Recording function, which stores the maximum, minimum, difference (maximum–minimum) and average input • Bar graph display, which responds more quickly than the numeric display — useful for detecting faulty contacts, potentiometer clicks and signal spikes • T1-T2 function, for taking two temperature measurements at the same time, which allows comparing two differenttemperatures
