Martindale EZ365 Advanced Socket Tester

In addition to detecting 28 socket wiring fault conditions and checking mains voltage levels, the Martindale EZ365 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.

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

The EZ365 also can check for L-NE polarity swap at the incoming supply and can be used to trip-test 30mA RCDs. The polarity swap test detects a serious fault condition that cannot be identified by normal socket testers and is easily activated by using the touchpad on the EZ365.

The EZ365 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 before servicing and installing mains-powered electrical and gas appliances.
