suitable start current range for the battery
capacity.
5. When the leads are connected and the
start current is set, the instrument shows
the battery voltage reading. If the battery
voltage is less than 12 V for a 12 V battery,
disconnect the instrument, charge the
battery and then test again. If the correct
battery voltage is not reached after
charging, the battery is defective. If no
value is shown, check that the instrument
is correctly connected. If the instrument
is connected correctly, the battery is
defective.

STARTER TEST
NOTE:
The engine should be warm during the test.
1. Disable the ignition system so that the
engine cannot start. See the vehicle
manufacturer's instructions.
2. Connect the test leads (1) and (2) to the
battery as shown in the instructions.
3. Get a helper to turn the ignition key so
that the starter turns round the engine.
4. Read o the voltage on the display
(4) while the starter is working. 9 V or
less indicates excessively high power
consumption. This could be a result
of poor contact, defective starter, or
inadequate battery.
IMPORTANT:
Do NOT push the TEST START (3) button
during this test.
TESTING OF CHARGING SYSTEM
NOTE:
The engine should be warm during the test.
1. Connect the test leads (1) and (2) to the
battery as shown in the instructions.
2. Switch on the engine and run warm at
idling speed. Never start or run the engine
in an enclosed area – risk of carbon
monoxide poisoning.
3. Read o the battery status on the LED
indicators over the display (4) as shown in
the table for analysis of charging system
status.
IMPORTANT:
Do NOT push the TEST START (3) button
during this test.
WARNING!
Risk of carbon monoxide poisoning.
Exhaust fumes from the engine contain
carbon monoxide, an odourless and highly
dangerous gas. Never start or run the engine
in an enclosed area.
