Allows you to lamp, ballast, bulb and pin continuity tests. Used to provide maintenance on fluorescent light bulbs by diagnosing ballasts and testing bulbs.
Lamp test: test bulb without removing from fixture.
Ballast test: easily determine if ballast is working.
non-contact voltage: quickly check for voltage presence.
Pin continuity test: tests if filaments have continuity.
Ballast-type test: determine if ballast is electronic or magnetic without taking fixture apart-identify energy wasting ballasts.
