Disconnect test
leads from voltage
before plugging in
thermocouple!
Insure the
temperature being
measured is stable.
Maintain good
contact between the
thermocouple and
what's being
measured.
WARNINGS
DISCONNECT AND UNPLUG TEST LEADS
before opening case.
TEST NCV FUNCTION ON KNOWN LIVE
WIRE before using.
DO NOT APPLY VOLTAGE greater than
30VAC or 60VDC to the thermocouple or the
jacks when the rotary dial is on OFF.
REMOVE THE THERMOCOUPLE when
taking voltage measurements.
DISCONNECT THE TEST LEADS when
taking temperature measurements.
DO NOT APPLY VOLTAGE TO THE JACKS
when the rotary dial is on microamps. Even low
voltages can cause a current overload and blow
the fuse. Replace blown fuse to regain function.
