The Martindale EZ150 Socket Tester is capable of performing wiring fault checks on standard UK 230V wall sockets as well as performing an earth loop impedance test which allows it to give a nominal earth path resistivity value. It has twin sets of three LEDs, one for earth loop and the other for fault checking. The multicoloured LEDs can indicate wiring fault types in socket testers and the tester works as soon as it is plugged in.
