5.9.
Non-Contact AC Voltage Detection
WARNING:
Risk of Electrocution. Before use, always test the Voltage
Detector on a known live circuit to verify proper operation.
1. Set the rotary function switch to the NCV/Live Position.
2. Press the MODE Button to select readings in “ NCV ”.
3. Hold the detector close to the AC voltage being tested.
4. If no signal is detected, the LCD will show “
EF ”, the NCV indicator light
will not flash and the buzzer sound will not trigger.
5. According to the detected signal strength, LCD displays different
horizontal lines.
• When the signal is strongest, the LCD displays four horizontal lines,
when the signal is weakest, only one line.
• Meanwhile, the NCV indicator light flashes and the buzzer triggers a
different sound.
Note: The sensing level varies with the distance between the sensing part
and the measured AC power cord.
Note: The detector is designed with high sensitivity. Static electricity or other
sources of energy may randomly trip the sensor. This is normal operation.
