3.1. Description of Indicators
The EZ165 uses two rows of LED's to indicate wiring condition,
mains voltage level and earth loop impedance.
The top row of three tricolour LED's marked LOOP TEST indicates
the range within which the measured earth loop impedance falls.
The bottom row of three tricolour LED's indicates the condition of the
wiring or if the mains supply is <195V or >270V or if the neutral to
earth voltage is >30V.
Note 1: The loop test will not be performed, and the loop test
indicators will not illuminate if there is a wiring fault or the
mains voltage level is outside limits.
Note 2: The level of the mains supply is only indicated if the wiring
is correct.
3.2. Self-Test
Every time the EZ165 is plugged in it will perform a self-test routine
by flashing each row of indicators once in the following sequence:
