Rel Function; Hold Function; Ncv Function (Non-Contact Voltage Detection) - VOLTCRAFT VC-530 Instruction Manual

- After measuring, remove the measuring adapter from the measuring device and
turn the measuring device off. Turn the rotary switch to „OFF".

REL function

The REL function allows a reference value measurement to balance possible line
losses such as with resistance measurements or residue magnetism of the current
sensor. For this purpose, the current indicated value is set to zero. A new reference
value is set.
Press the REL key (8) to activate this measuring function. „REL" appears on the dis-
play.
In order to deactivate this function, press the REL key again and the REL display
will disappear.

HOLD function

- With the HOLD function the current measurement value can be „frozen" on the dis-
play.
- By pressing the HOLD key (4) the measurement is interrupted and the last mea-
surement value displayed. If the HOLD function is active, „HOLD" is displayed.
- Press HOLD again to deactivate the HOLD function.

NCV function (non-contact voltage detection)

The NCV function (non-contact voltage detection) enables detecting the existence
of voltage on conductors without contact. The NCV sensor is installed at the end of
the current sensor.
Bring the NCV sensor into contact with a conductor. If there is voltage, the red illu-
minating diode lights up (2). This function is only active when the meter is switched
on.
