4.8. 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.
„ Set the rotary switch to the NCV position.
„ Hold the detector close to the AC voltage being tested.
„ If no signal is detected, the LCD will show EF, NCV indicator light doesn't flashes and the buzzer
is no sound.
„ According to the detected signal strength, LCD displays different horizontal lines.
„ When the signal is strongest, LCD displays four horizontal lines, when the signal is weakest,
only one line.
„ Meanwhile, NCV indicator light flashes, buzzer make 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.
The absence of a voltage indication in the NCV function does not mean that there is no voltage.
To confirm the absence of a voltage, use a VAT.
The presence of other voltages nearby can trigger non-contact voltage detection.

Note: Intrinsic uncertainty is stated at 18 to 28°C (65 to 83°F) and less than 75%RH.
Note: Intrinsic uncertainty is expressed as a percentage of reading (R) plus a number of digits (ct):
