Operating Instructions
AC VOLTAGE DETECTION
1. Lift the probe tip from the storage area and extend the
telescoping rod.
2. Twist the rod into the LOCKED position as indicated.
3. Slide the ON/OFF switch to the ON position. The green ON light
will illuminate and the red detection light may flash.
4. Adjust (decrease) the sensitivity adjustment until the red flashing
voltage indicator light and the beeper just stop.
5. Place the probe tip on the wire or object to be tested. If voltage is
present the red flashing light and beeper will continuously alert.
6. To turn off the audible beeper, slide the ON/OFF switch to the
position.
NOTE: RF signals in close proximity to the detector may cause the light
and beeper to latch into a constant tone and light indication. Wait until
the RF signal has disappeared before proceeding with detection.
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.
Battery Installation
1. Unscrew the probe tip..
2. Insert two 1.5V button batteries (observe polarity).
NOTE: If your meter does not work properly, check the battery to make
sure that it still good and that it is properly inserted.
