※
When working under high voltage systems, please
wear the insulation gloves and rubber shoes. Do not
touch live conductors with this Non-contact high
voltage detector.
An increase in voltage means an increase in its radiated
field strength. The radiated field strength quickly
decreases with distance and/or ground shielding. The
radiated field from a cable where conductors supplying
3-phase power are close together tend to cancel out.
The rotary switch, or attenuator, is used to identify and
differentiate various HV live cables.
※
The detector should only be used in conjunction
with an insulated rod or hot stick when measuring
high voltage.
Check to see if the Non-contact high voltage detector is
in good operating condition. Select the appropriate test
range. It is advised that you start with a lower test range
setting than the actual working voltage. Then perform the
test again with the higher settings. The user may also opt
to use a lower setting to check for lower voltages on a
conductor.
With the hot stick, gradually move the Non-contact high
voltage detector towards the live conductor until its
warning signal is triggered. Again, do not touch the live
conductor with the Non-contact high voltage detector.
