Description

Description

In addition to detecting 28 socket wiring fault conditions and checking mains voltage levels, the EZ165 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 properly and prevent electrocution when faults occur. In contrast basic socket testers only indicate the presence of an earth and will do so even when resistance values are dangerously high.

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 fast identification of the source of common faults. A look up chart on the tester provides further fault diagnosis.

The EZ165 is an Advanced Socket Tester as defined by the Health & Safety Executive as it indicates earth loop impedance.  Advanced Socket Testers offer a simple solution to verifying socket earthing and are commonly used by engineers and technicians prior to servicing and installing mains powered electrical and gas appliances.
