Non-Contact Voltage Detection - VOLTCRAFT VC-20 Notice D'emploi

- The display shows the unit „nF".
- Now connect the two test prods with the object
to be measured (condenser). After a short while
the display shows the capacity.
- As soon as „OL." (overflow) on the display, you
have exceeded the measuring range or the mea-
suring circuit has been interrupted.
h) Non-contact voltage detection
The measuring device features a non-contact voltage detector. The
detector also works with alternating voltages of 100 to 600 V, even
when the measuring device is turned off.
The voltage sensor (5) is located on
the top of the device.
The detector serves to find cable
breaks in live cables, for example.
Guide the measuring device along
the object to be tested with the sen-
sor surface (5).
If alternating voltage is detected,
the NCV display (6) lights up.
The possible distance depends on the among of alternating volt-
age.
The voltage detector only serves as a quick test and
does not replace contact voltage measuring.
The display also responds in the event of static
charges, as the detector detects electric fields. This
is normal and not a defect.
