The Battery Charger Tester permits fast and precise testing of any battery charger. A convenient A.C. power output receptacle is provided to power the charger while a circuit breaker protects the tester from overloads. The voltmeter and ammeter indicate charger output and a variable load permits testing the maximum output current of the charger. For precise charger output voltage calibration, a pair of terminals permits connecting a digital voltmeter.
A built-in bar graph is provided to test the bar graph indicator drive circuits of those chargers equipped with remote bar graph displays.
