Wiring And Voltage Check - Martindale Electric EZ165 Instruction Manual

3.3.1 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.
