The Martindale EZ365 is a socket tester that additionally checks the earth loop impedance of the wiring under test and indicates the range that the measured earth loop impedance falls within. If the wiring is faulty or the mains voltage is not within limits the earth loop impedance test is not performed.

The EZ365 also indicates if the mains voltage is below 195V or above 270V or if the neutral to earth voltage is greater than 30V. The ‘T Safe’ technology employed by the EZ365 allows the earth loop impedance to be measured with a 30mA or higher RCD in circuit without it tripping.

The EZ365 is designed to be plugged into a socket and removed after the test has been performed. If the EZ365 is left plugged into a socket it will go into standby mode after approximately 10 minutes. The illuminated LED indicators will go blank and the two centre LED’s will flash amber and the buzzer will beep every 5 seconds.
