Martindale EZ165 Socket & Non-Trip Earth Loop Tester
The EZ165 detects 28 socket wiring fault conditions and checks mains voltage levels. In addition, it verifies the earth wiring by carrying out a non-trip earth loop test and indicating its value in 6 discrete ranges from less than 1.7Ω to 500Ω.
A low earth resistance is essential for safety disconnection devices to work correctly and prevent electrocution when faults occur.
Socket polarity and earth wiring faults are identified by a combination of red LEDs. The 3 LEDs correspond to neutral, earth and live connections to aid in fast identification of the source of common faults. A look-up chart on the tester provides further fault diagnosis.
