METER NOT OPERATIVE
Step 1.
Turn the master calibration control (accessible through
a finger hole in the bottom) to maximum.
If the reading is less than full scale, remove screws
(1) that attach the bottom plate (2) and replace the 9
volt zinc carbon type battery (3).
Do not use a mercury
or alkaline battery.
Step 2.
The meter is a sealed unit with the battery compartment
the only accessible area.
If general cleaning of terminals, probes and cell and
replacing the battery does not correct the malfunction,
the meter must be replaced.
