Electrical Receptacle Wall Plug AC Outlet Ground Tester with GFI Reset

Use this tester to verify that an AC wall outlet is wired properly. A safety "must" for all homes and businesses. The tester itself is a small device which looks like the "plug in" end of a power cord, with several lights on it rather than an attached cord. Although a multimeter could be used to perform a series of tests which would give the same results, an outlet tester can perform the entire array of tests by simply plugging the device into the outlet once and observing the state of the lights.
