How do I use the Non-contact AC Voltage Detector?

• Risk of Electrocution. Before use, always test the Voltage Detector on a known live circuit to verify proper operation.
• Set the rotary function switch to the NCV position.
• Hold the detector close to the AC voltage being tested.
• If no voltage is detected, the LCD will show “EF”, NCV indicator light will not flash and there will be no beeper sound.
• According to the detected voltage field, the LCD will display different horizontal lines. When the voltage field is strongest, LCD displays four horizontal lines, when the voltage field is weakest, only one line. At the same time, the NCV indicator light flashes, the beeper will make a different sound. 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. The detector is designed with high sensitivity. Static electricity or other sources of energy may randomly trip the sensor. This is normal operation. Insulation type and thickness, distance from the voltage source, shielded wires, and other factors may affect reliable operation. Use other methods to verify live voltage, if there is any uncertainty.
