Battery tester is designed to test
the state and condition of 6 and
12 volt batteries. Before using this
product, read this leaflet thoroughly and fol-
low the instructions carefully, with particular
emphasis on the safety precautions. This
ensures your own safety and that of others
around you.
With the meter disconnected from the bat-
tery, make sure the gauge needle is set to
zero, using the screw on the front of the
gauge as necessary.
Safety precautions
Always avoid creating sparks in a battery-
charging environment, as this could cause
fire, or even an explosion. Similarly, it is
vital to avoid creating sparks when testing a
battery installed in a motor vehicle as spikes
in the system could cause serious damage
to the vehicle electronic circuitry. Make sure
that the red or positive clamp does not touch
any other part of the vehicle, and be particu-
larly careful where you place the tester inside
the engine compartment. The main body of
the tester is metal, and if placed carelessly,
it could cause a short circuit and damage the
electrical system. Avoid dropping the battery
tester as this could cause damage, which
may prevent it from working.
Battery analysis (Meter reading after 5 seconds with load switch on)
Load test
Battery condition
OK (green band)
Battery capacity is good. May or may not be fully charged. Check the state of charge by checking
Specific Grafity (SG) with a hyddromete. If SG is less than full charge, check for possible charging
system trouble. Recharge battery to full level.
Weak or Bad
Battery capacity is unsatisfactory. Battery may be defective, or partly discharged. To determine
(needle steady)
which, check SG. If SG is over 1,225 the battery is considered defective. If SG is below 1,225,
recharge battery and retest. If difference in cell to cell SG is greater than 0,025 (2 points), cell
trouble may exist. If charge does not bring SG to full charge level, then battery is either sulfated,
or has lost its active material.
Weak or Bad
Battery may be defective (i.e., a bad cell). For a quick check, release loadswitch, and note volt
(no needle)
meter reaction. If voltage recovers to its full potential after only a few seconds, the battery is pro-
bably defective. If the voltage recovers slowly, the battery may only be very run down. For more
accurate results, check SG and follow above procedure.
Battery test
Connect the red clamp to the positive ter-
minal, and the black clamp to the negative
terminal, make sure the contacts are clean
and firm, and that on small batteries, there
is absolutely no possibility of the clamps
touching each other. Push the spring-loaded
switch in either direction and hold for at least
5 seconds to allow the load to take effect.
With the load switch held, read the condition
of the battery on the scale provided, referring
to the Battery Analysis chart and the battery
tester.
Charging system test
Connect the leads to the battery, as above,
and run the engine at a fast idle speed. Read
the gauge (charging system). Do not operate
the load switch.
Maintenance
As the metal clamps are liable to come into
contact with battery electrolyte, it is advisa-
ble to wipe them clean and dry after use, and
apply a thin film of silicone grease to prevent
the possibility of corrosion.
