What does a Battery Charger Tester do?
Tests electric battery chargers, using portable testing unit: Clamps battery charger cables to appropriate tester terminals. Pushes control buttons to supply battery charger with specific amount of current that registers on charger meters and compares meter reading with tester meter to determine that meter is registering accurately. Increases current flowing from tester to charger to heat battery charger coil until grease and dirt are burned out. Turns off switches and removes battery charger cables from tester, approving satisfactory battery chargers and returning defective battery chargers for adjustments.
