Fuse Replacement
The fuse is in series with the “OHM” input jack. If this fuse is open the
OHM circuit will not work. When replacing the fuse be sure to replace it
with a fuse of the same current rating and internal resistance. The use
of a fuse with a different internal resistance may cause the accuracy of
thee “OHMS” scale to be off. Remove the screws in the rear of the case
for access to the fuse. Fuse should be 0.3 Amp / 0.9 OHM resistance.
Mechanical Zero Adjust
The pointer is set to register 0 at the left edge of the scale when there
is no input to the MCP9A and it is laying face up on a flat surface. If
the pointer does not register 0, it may be reset to that position by
carefully adjusting the black screw in the meter face, just below the
“LOCK” switch.
