The three high brightness, extended life neon lights on the CP501 Check Plug are indicators that the 13A UK sockets are connected correctly. The CP501 Check Plug is a quick and simple socket tester. One or more neons not lighting up indicates possible problems. Because of this failsafe mechanism, an issue is indicated by any neon that isn't lighted! An excellent socket tester. The flame-resistant ABS housing of the Martindale CP501 check plug has a contoured design that makes removal simple. Significantly below RCD trip criteria, the CP501 Check Plug causes less than 5mA of earth leakage. The CP501, like all socket testers, does not evaluate the quality of the earth; it merely confirms its existence.
