Operating Instructions
AC VOLTAGE DETECTION
1. For low voltage testing (24 to 100V), press
and hold the 24V button (5). For standard
electrical work (>100V, this is not necessary.
2. Touch the probe tip (7) to the hot conductor
or insert into the hot side of the electrical
outlet.
3. If AC voltage is present, the detector cone
will illuminate (6) and the detector will beep.
NOTE:
The conductors in electrical cord sets
are often twisted. For best results, rub
the probe tip along a length of the
cord to assure placing the tip in close
proximity to the live conductor.
NOTE:
The detector is designed with high
sensitivity. Static electricity or other
sources of energy may randomly trip the
sensor. This is normal operation.
