Maintenance And Service
Warning
Make sure the test leads take off the terminal and the
circuit as well as power off the meter if want to open
the meter cover.
1.General Service and Maintenance
Periodically wipe the case with a damp cloth and mild

Battery Specification: 9V 6F22 or NEDA 1604/
IEC6LR61
Operating Steps:
(1) Turn the power in “ off "situation, then remove the
test lead out of the meter.
(2) Use screwdriver to take off the screw on the
E
attery cover. Then you can take off old
E
attery for
replacing.
(3) User screwdriver to take off two pieces of screws,
then you can replacing the
