IMPORTANT INFORMATION
Battery tester features
ADJUSTMENT SCREW The screw is used to set
the dial pointer to zero on the battery / charging
system scale.
METER SCALE The scale represents the “state of
charge” of the battery. Use the 6-volts or 12-volts
on the scale to check the voltage level and condition
of 6 V and 12 V batteries during the battery loadtest.
Use the charging system section on the scale to
check the voltage level and condition of the battery
during the charging system test.
POSITIVE AND NEGATIVE CLAMPS
These clamps are connected to the positive and
negative terminals of the battery respectively.
SPRING-LOADED SWITCH
This switch must be held ON for 10 seconds
while testing the 6 V or 12 V batteries.
The MotoMaster 100 A Battery Tester is designed
to test the voltage level and condition of all types
of 6 V and 12 V automotive lead-acid batteries and
to measure motor starting current. The tester is
provided with colour-coded easy-to-read meter
scale, heavy-duty, insulated clamps, and is made
of steel.

Temperature compensation
This battery tester’s accuracy will be affected
by cold temperatures. For every 20 F (11°C)
drop in battery temperature, the battery tester
will indicate the battery nominal rating of 200
cranking amperes less than the actual rating
of the battery.
Consider the case if the battery tester tests a
battery with nominal rating of 1000 CCA.
Refer to the table below for the position of the
dial pointer in the meter scale with respect to
drop in temperature:
