12.1 Turn the function dial to the NCV position.
12.2 Put the NCV detector (top left corner of the meter) close to the wire (AC) under test.
12.3 If the voltage of the wire is ≥50 V RMS (frequency: 50/60 Hz), the red indicator light will be on
and the buzzer will beep. If no voltage is detected, the LCD will display "EF". As the intensity of
the detected voltage increases, more segments "-" will be displayed, and the frequency of buzzer
beeping and red indicator light flashing will increase.
Caution:
• The detected voltage level varies with the distance between the NCV detector and the wire under
test.
• The detected voltage level is for reference only, not for specific measurement. The frequency of the
detected voltage should be 50/60 Hz.
• Hold the meter casing for non-contact voltage detection.
