WARNING: Phase testing
cannot be performed in
unfavourable locations, e.g.
on ladders with wooden
rungs or in rooms with insu-
lated floor coverings and in
AC voltage systems not
properly bonded to earth.
To perform the phase test,
contact the small test
probe with the phase
(> 90 V AC) of the AC
voltage system and touch
the phase tester contact
on the indicator handle
with your thumb. The 6 V
step indicator (+ and –)
will light up upon phase
contact and an acoustic
signal is also given.
