11.3 Non-contact voltage testing
The non-contact voltage (NCV) detection function can detect AC voltage on con-
ductors without touching them.
Due to the high sensitivity sensor, static electricity or other sources of energy may
trigger the sensor. This is normal operation.
Risk of electric shock!
■
Before use, always test the voltage detector on a known live circuit
to ensure safe operation.
■
Insulation type, thickness, and distance from the voltage source
may affect detection.
■
Always verify measurements using test leads before touching po-
tentially energized circuits.

1. Set the rotary switch to: NCV.
"NCV" and "EF" will appear on the dis-
à
play.
2. Place the sensor tip near the conductor.
If AC voltage is present, the tri-colour
à
LED will light and a beep will sound.
3. If the detected voltage increases:
the beeping will get faster.
à
the tri-colour LED changes from
à
green → yellow → red.
4. Switch the power OFF after use.
