Non-Contact Voltage Detection "Ncv - VOLTCRAFT VC-590OLED Notice D'emploi

i) Non-contact voltage detection "NCV"
The voltage detector is intended as a means for quick testing and is not a sub-
stitute for contact voltage detection. This method is not permissible for check-
ing the absence of voltages in order to perform work.
The NCV function (non-contact voltage detection) is used to detect the presence of alternating
voltage in conductors. The NCV sensor (1) is located in the tip of the current sensor.
Bring the NCV sensor as close as possible to a conductor. The distance
may not exceed max. 10 mm. If an alternating voltage is detected, the
red NCV LED (3) flashes and a beep sounds. The display shows the
signal strength using 4 arrow symbols.
Due to the high sensitivity of the NCV sensor, the LED may light up in
the case of static charges. This is normal and not a malfunction.
Always test the NCV first on a known AC voltage source to
prevent false reads. False reads pose a risk of electric shock.
