Auto Power Off Function - VOLTCRAFT VC-530 Instruction Manual

Due to the high-sensitivity NCV sensor, the illuminating diode can
also light up for static charging. This is normal and not a malfunction.
Always test the NCV function first on a known voltge source in order
to prevent faulty detections. Faulty detection results in a risk of an
electric shock.
Automatic power OFF function
The measuring device turns off automatically after 15 minutes if no key or the rotary
switch is operated. This function saves battery power and extends the service life.
In order to switch the measuring device back on after automatic deactivation, oper-
ate the rotary switch.
Min/max function
With the min/max function the smallest (min) or the biggest (max) measurement val-
ue can be automatically stored or shown on the display. This means that any occur-
ring peaks or drops can be securely detected.
To activate this function, select with the MIN/MAX key (14) whether the biggest
(MAX) measurement value or the smallest (MIN) measurement value should be dis-
played.
In order to return to the normal measurement module, press the MIN/MAX key (14)
for approx. 2 seconds.
Background illumination
The measuring device is equipped with a background illumination for the display -
this makes it easier to read in dark rooms. To activate background illumination,
press HOLD key for approx. 2 seconds while the measuring device is switched on.
In order to not use the battery unnecessarily, the background illumination switches
off after approx. 10 seconds.
