The Fieldpiece SMG5 Digital Megohm Meter is a compact standalone meter designed for checking
HVAC compressor insulation. The Fieldpiece SMG-5 provides a 1000V voltage source, monitors
current, and displays the resistance between the test points. Maximum current output is >1mA.
The Fieldpiece SMG5 can be used to determine the condition of insulation from winding to ground
in a motor, compressor, or transformer.
The Fieldpiece SMG5 Megohm Meter is in a class of it’s own. The Fieldpiece SMG5 affordable
and was designed with your safety in mind. When used properly, detachable lead tips and probes
along with and alligator lead tip allow for one-handed testing. The compact, slim shape allows
for easier testing as well while the Auto power off (APO) helps the user to conserve battery
Why a Digital Multimeter (DMM) Often Isn't Enough
To test resistance, a DMM supplies low voltage (>1V) to the test points and is capable of
delivering only a few milliamps. It's not a high enough voltage to detect high resistance problems
that might indicate moisture and other contaminants and it's not enough current to measure lower
values of resistance.
