13. Non-Contact Voltage (NCV) Detection (Picture 16)
Picture 16
1) Turn the function dial to the NCV position.
2) Bring the NCV detector (top left corner of the meter) close to the wire (AC)
under test.
3) If the voltage of the wire is ≥50Vrms (frequency: 50Hz/60Hz), 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 for buzzer beeping and red indicator
light flashing will be higher.
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 50Hz/60Hz.
Hold the meter casing for non-contact voltage detection.

the SELECT button in the off state, and then turn on the meter. To recover the
function, restart the meter.
2) Buzzer alarm during measurement: When the input voltage >1000V or current
>10A, the buzzer will sound an alarm.
3) Low battery indication: When the battery voltage is ≤4.6V ±0.2V, "
