General remarks Once the charger has been connected to the battery, the following test phases run
(continued) automatically in sequence:
-
-
-
Testing the The charger measures the open circuit voltage of the battery. If the battery was not used
battery open for at least two hours, then this is referred to as open circuit voltage.

If there is no starting procedure after 30 seconds, the charger changes over automatical-
ly to the alternator test. If the starting procedure is not possible, charge (or check) the
battery.
Test alternator While the engine is running, the charger checks the voltage the alternator is supplying to
the battery.

Battery open circuit voltage test
Battery startability test
Alternator test
NOTE! All battery and generator test results are for information only and may
differ from the actual values. The charger checks the entire system. The results
are therefore to be seen as recommendations only.
The best results are obtained when using a direct connection to the battery.
Switch off engine and ignition, shed all loads

All display elements on the display are activated. Depending on the type of charger,
the respective voltage(s) and/or symbol for the type of battery are displayed.
