Pin Test
The pin test (filament test) can be used on dual pin fluorescent lamps that
have a filament under the metal cap. The filament is used to excite the gas
inside the tube and turn it on. The lamp will not function correctly if the
filament is broken.

Turn the power off to the light fixture before removing the lamp from
the fixture.
1. Pin test is always on. Plug the lamp pins into the pin test slots on the
back of the tester.
• If the tester does not beep and LED indicator is not on, the filament
is broken. Replace the lamp.
• If the tester beeps and LED indicator is on, the filament is functional.
The pins are good.
