HOW TO TEST
TESTING PROGRAMS AVAILABLE
• BATTERY – Reveals a battery's current charge level.
• START POWER – Monitors a battery's output during
the strain of engine cranking, to evaluate overall
condition.
• ALTERNATOR – Establishes whether a vehicle's
charging system is correctly charging the battery or not.
BEFORE TESTING
1. Read the SAFETY section in the manual to make sure
you connect/disconnect the unit to the battery/safely.
2. Before doing the START POWER or ALTERNATOR
tests, make sure the battery is fully charged. If it isn't,
false results may occur. Before doing a BATTERY test,
ensure ambient temperature is at least 41 °F (5 °C) and
that the battery has not been charged – by a mains
charger or the vehicle – for at least an hour before
testing.
3. Lamp 4, 5, and 6, show the results. 4 (red) indicates
BAD, 5 (orange) FAIR, 6 (green) OK.
TESTING
(MAINS POWER NOT REQUIRED)
1. Connect the charger to the battery. Lamp 4, 5, and 6
illuminate in sequence to show the charger is in Testing
Mode and ready.
