This is the Fluke SM100 socket tester for correctly identifying the status of the internal wiring within a standard 3-pin plug. You simply insert the Fluke SM100 into a socket (when the socket is powered ON), and it will detect correct wiring or whether there are some problems for the installation. The LED indicators will detect the correct wiring, the missing earth, the live earth reverse, and the missing neutral.
Insert this tester directly into a standard three-pin socket to check the internal wiring without the need to remove the socket panel. The tester uses LED indicators to showcase the detected status of wiring and can show correct wiring, missing earth, live earth reverse and missing neutral. A handy guide is included on the front of the tester for reference.
