5.2 Non-contact voltage detector
WARNING
The detector is designed to detect the presence of a
voltage, not for determining its absence.
Electric shock hazard. Before using the tester, check
if its operational by testing it on a known AC voltage
(i.e. next applicable socket with live voltages).
To activate the detector:
set the rotary switch at any position,
touch the tip of the detector to the tested object.
If the AC voltage is present, the indicator light will glow red.
The wires in the extension cords are often twisted. For
best results, move the tip of the detector along the wire to
locate the live line.
The indicator has a high sensitivity. It can be randomly
actuated by static electricity or other energy sources.
This is normal.
The type and thickness of the insulation, distance from
the power source, shielded cables and other factors may
affect the operation of the tester. If you are unsure about
the test result, check the presence of voltage in a differ-
ent way.
