Localising electrical voltages
Position the detector tip in the
area to be tested (e.g. cable,
socket. etc.).
To determine the L/N conductors, then check the neutral conductor,
no signal should appear here.
!
For safety, check all three phase conductors (L1, L2, L3) for
the presence of voltage!
!
Replace the batteries if the output is weak or reduced.
To make sure check the PE connection, the installation is not safe if
a signal appears here. Observe the technical safety regulations for
working on electrical systems, especially:
1. Safely isolating from power supply
2. Securing to prevent system being switched on again
3. Checking zero potential, two-pole
4. Earthing and short-circuiting
5. Securing and covering adjacent live components
Please be aware that even if a visual signal is not displayed,
voltage may still be present. Differences in the design of the
!
connection socket or the nature of the insulation (thickness
and type) can affect functionality. Voltage cannot be detected
behind panels and metal covers.

The detector tip lights up to
show a voltage is present.
