Operating Instructions

Note: For new meters, remove the battery end cap and then

remove the battery insulating strip.

AC VOLTAGE DETECTION

1. Touch the probe tip (6) to the hot
conductor or insert into the hot side of
the electrical outlet.

2. If AC voltage is present, the detector
cone will illuminate (5).

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.

FLASHLIGHT

Press and hold the flashlight ON/OFF button (3) to turn on
the flashlight (1).

BATTERY INSTALLATION

1. Remove the end cap (2) by gently lifting the pocket clip (4)
to release the catch.

2. Insert two AAA batteries (observe polarity).

3. Replace the end cap

NOTE: If your meter does not work properly, check the

battery to make sure that it still good and that it is
properly inserted.
