How do I test a ballast with a multimeter?
How do I test a ballast with a multimeter?
To measure it, set your digital multimeter to around a thousand ohms resistance setting. Connect the black leads to the white ground wire on your ballast. Afterward, test every other wire with the red lead. When you do this test, a good ballast will return an “open-loop” or max resistance.
How can you tell if a ballast is good?
If the ballast is good, an analog multimeter has a needle that will sweep to the right across the measuring scale. If the ballast is bad, then the needle won’t move. If you’re using a digital multimeter, often the digital readout will possibly list a “1” when it doesn’t find a measurable resistance.
How do you test a fluorescent tube with a multimeter?
Set a multimeter to the ohm (Omega symbol) setting, then touch one tester probe to each of the pins at the end of the bulb. If the tester shows a reading between 0.5 and 1.2 ohms, the bulb has continuity. Repeat the test at the other end of the bulb.
