General remarks
Do not connect the charger to the mains supply during testing. In all tests, the charger
draws its supply from the battery being tested.
Once the charger has been connected to the battery, the following test phases run
automatically in sequence:

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.
Warning! Risk of injury and damage from exposed, rotating vehicle parts.
When working in the vehicle's engine compartment, take care that hands, hair,
items of clothing and charger leads do not come into contact with moving parts,
e.g. fan belt, fan, etc.
Battery open circuit voltage test
Battery startability test (only on chargers for motor vehicle applications)
Alternator test (only on chargers for motor vehicle applications)
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.
