Operating Instructions
AC CURRENT 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. Move the probe tip near the current carrying conductor until the
tip flashes and beeper sounds.
6. Slowly adjust the sensitivity and reduce the distance between the
probe and conductor to pinpoint and identify the conductor.
7. 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.
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.
