Operation

WARNING: Risk of Electrocution. Before use, always test the Detector on a known live circuit to verify
proper operation.

latch into a constant tone and light indication. Wait until the RF signal has disappeared before proceeding with
voltage detection.
1. Turn the On/Off-Sensitivity switch (2) clockwise to turn the unit on.
2. Set the Sensitivity adjustment (2) to the high (counterclockwise) position
3. If the detector begins to beep/flash (1), slowly reduce the sensitivity (clockwise) until the beep stops.
4. Move the detector voltage sensor (1) near the conductor until the tip flashes and beeper sounds.
5. Slowly adjust the sensitivity (2) and reduce the distance between the sensor and conductor to pinpoint and identify
the conductor.
