Martindale EZ365 Socket, Earth Loop & RCD Tester

Martindale EZ365 Socket, Earth Loop & RCD Tester

The EZ365 is an Advanced Socket Tester, recognised by the Health & Safety Executive for its ability to indicate earth loop impedance. This sophisticated device not only detects 28 socket wiring faults and checks mains voltage levels but also carries out a non-trip earth loop test. It displays earth wiring values across six discrete ranges, from less than 1.7Ω to 500Ω.

Low earth resistance is crucial for the effective operation of safety disconnection devices, safeguarding against electrocution during faults. Unlike basic testers that only confirm the presence of an earth connection, the EZ365 ensures that the resistance values are not dangerously high.

The tester employs a trio of red LEDs, representing neutral, earth, and live connections, to quickly pinpoint socket polarity and earth wiring faults. A handy lookup chart on the device aids in fault diagnosis.

Additionally, the EZ365 is equipped to identify L-NE polarity swaps at the incoming supply, a serious fault condition often missed by standard testers. This function is easily activated via the touchpad. The device can also be used to trip test 30mA RCDs.

Overall, the EZ365 serves as a comprehensive tool for engineers and technicians, ensuring the safety and correctness of socket earthing before servicing or installing mains powered electrical and gas appliances.
