When you’re upgrading or replacing your ballasts, you need to know whether they’re electronic or magnetic. That’s where the ABC-100 ballast checker/ballast discriminator comes in. This Advance electronic versus magnetic ballast checker is incredibly easy to use, even for beginners.
The Advance ABC-100 electronic vs. magnetic ballast checker can work up to 15 feet away from the light fixture, so high ceilings are no problem. Since it operates on two AA batteries, this efficient little ballast checker never requires charging. All you need to do is point it toward your fixture, click the button on the front and wait for the light to flash; green means your ballast is electronic, while orange means it’s magnetic. This cost-effective, long-distance ballast checker, which is also known as the Sensor Switch D-1 Ballast Discriminator, will save you from the hassle of getting up-close-and-personal with your fixtures.
