Description
The Greenlee DM-200A, DM-210A, and DM-510A Digital Multimeters are hand-held testing devices
with the following measurement capabilities: AC and DC voltage, AC and DC current, frequency, and
resistance. They also check diodes and verify continuity. An optional optically isolated computer inter-
face with software facilitates the recording of readings from the meter to a computer.
Other specialized capabilities and functions common to all meters include:
• Backlighted LCD for reading in dim conditions.
• Beep-Jack™ audible warning alerts the user with a beep and an error message on the LCD if the
test lead is plugged into the or input terminal while the selector switch is not in the mA/μA A mA/μA
or position.A
• Non-contact and single-probe voltage detection capability.
• Bar graph display, which responds more quickly than the numeric display — useful for detecting
faulty contacts, potentiometer clicks, and signal spikes.
• Relative zero mode.
• Data hold mode.
• Selectable automatic power off.
The DM-210A and DM-510A multimeters have the following additional capabilities: temperature
(K-type thermocouples only) and capacitance.
The DM-510A multimeter has an AutoCheck™ function for automatic selection of AC voltage, DC
voltage, and resistance with low input impedance to mask “ghost” voltages. The DM-510A also has a
crest function, which captures voltage or current signal peaks, as well as a recording function, which
stores the maximum and minimum input readings. The DM-510A is a true RMS meter.
