To test a GFCI outlet using the Fluke ST120+ GFCI Socket Tester, follow these steps:
1. Before plugging the Fluke ST120+ into the GFCI outlet, push the GFCI test button on the outlet itself to trip the GFCI. If the GFCI does not trip, it indicates a faulty outlet that should be replaced.
2. After the GFCI trips, push the RESET button on the outlet to reset it.
3. Plug the Fluke ST120+ into the GFCI outlet.
4. Push the blue GFCI test button on the Fluke ST120+ and hold it for a minimum of 6 seconds. As you push the GFCI test button, the LED to the left of the button briefly turns on. Once the GFCI trips, all of the LEDs on the Fluke ST120+ go out.
5. If the GFCI does not trip, or if any of the LEDs on the Fluke ST120+ remain on, it indicates a problem with the wiring of the outlet, the outlet itself, or the Fluke ST120+. In such cases, it is recommended to consult an electrician to determine the problem.
Please note that these instructions are a summary and it is important to refer to the Fluke ST120+ GFCI Socket Tester Instruction Manual for complete and accurate information.
