Operation; Hold Function; B) Ncv-Function (Contact-Free Voltage Recognition) - VOLTCRAFT VC731 Bedienungsanleitung

11. OPERATION

a) HOLD Function
Use the HOLD function to permanently display the current measured value and interrupt
the measurement.
For this, push the button "HOLD" during a measurement (6). The display indicates "HOLD".
To deactivate, push the button "HOLD" again briefly (6). You may continue the
measurement.

b) NCV-Function (Contact-Free Voltage Recognition)

The NCV function ("non-contact-voltage detection") leads to contact-free detection of the
presence of voltage at the conductors. The NCV sensor is attached at the top of the
current sensor.
Touch the NCV sensor to a conductor. When voltage is present, the red LED (2) lights up.
This function is only active with the current injection probe on.
The highly sensitive NCV sensor may cause the LED to light up briefly at static
charges as well. This is normal and not a malfunction.
Always test this function at a known voltage source to avoid incorrect detection. There is a
danger of electric shock at incorrect detection!
