Adjusting the meter
1) Fine adjustment
a. Before repairing check to see whether
the voltage of the battery used exceeds
1.56V (1.58V under normal condition)
For both spot and Average metering can
be adjusted by moving Variable resistor
180° turn of the adjusting lever varies
by approximately 0.8 step after removing
Bottom cover.
C. Average metering can be adjusted by moving
Variable resistor on Printed circuit with
resistor without removing Top cover
Bi
2) Major adjustment
Remove Top cover and confirm that
soldering is good.
The turn of meter adjusting lever
make spot and Average metering change
In case more than 1 step adjustment is
required.
adjust the meter by changing the position
of wrapping Chainlet round Meter drum.
(Refer to item of replacing Meter drum.)
