Wiring And Voltage Check - Martindale Electric EZ365 Instruction Manual

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.

3.4.1 Wiring and Voltage Check

The condition of the wiring at the socket under test or any out of
tolerance supply voltage will be indicated by the LED sequences of
figure 1 on the lower row of LED's. If a wiring fault is detected or the
supply voltage is out of tolerance the top loop indicator LED's will
not illuminate as a loop impedance measurement is not made.

In the event of a fault being indicated, investigation should only be
carried out by a suitably qualified electrician.
