Features
The Greenlee DM-820A Digital Multimeters is a 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 meters 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 meter to a computer.Measures voltage, current, resistance, capacitance and frequency

Founded in 1862, Greenlee Tools got its start as a toolmaker when two brothers needed to manufacture their invention (a special drill surrounded by chisels). With the success of this effort, the Greenlee brothers quickly took on making other woodworking tools and other machinery including a machine that laid track for the railroad. In the mid-80s and beyond, Greenlee added on other toolmakers and diversified the kinds of tools they make and now Greenlee manufactures tools used by tradesmen in all vocations from communications to hydraulic pumps, plumbing, telecom, test equipment and many more. Greenlee is widely recognized as an industry leader for quality hand and industrial tools.
