The 3 LEDs correspond to neutral, earth and live connections to aid fast identification of the source of common faults.

Its clear display, self-test function, and easy-to-use design make it a great choice for anyone who needs to quickly and accurately test industrial sockets for safety and reliability. See the NEW Martindale E-Ze Check Xtra™ earth loop impedance socket tester below for verification of earth loop impedance.
