Description
The Greenlee DM-860 Digital Multimeter is a hand-held testing device with the following
measurement capabilities: AC and DC voltage, AC and DC current, percent of loop current, two
channels of temperature (K-type thermocouples), frequency, duty cycle, resistance, and
capacitance. It also checks diodes and verifies continuity.
The DM-860 warns the user with a beep and an error message on the LCD if the test lead is
plugged into the mA/
µ
A or A input terminal while the selector switch is not in the mA/
µ
A or A
position. The meter features a bar graph display that responds more quickly than the numeric
display—useful for detecting faulty contacts, potentiometer clicks, and signal spikes. An
optional optical RS-232 computer interface and software facilitates the recording of readings
from the meter to a computer.
Other specialized functions and capabilities include:
• AC bandwidth to 100 kHz for voltage or 10 kHz for current
• MAX/MIN function which stores the maximum, minimum, and difference
• Crest capture mode to capture voltage or current signal peaks
• Selectable between 50,000 or 500,000 counts resolution when measuring
DC voltage or frequency
• Relative zero mode
• Automatic or manual ranging
• Intelligent automatic power off
• Backlighted LCD for reading in dim conditions
