IMPORTANT
This device’s sensitivity can be adjusted to the exact
position of a metallic object or electrical conductor.
First, set the wheel. Once the light goes off, turn the
wheel a little further to narrow the detection zone.
SAFETY
When the device indicates “no current” (no flashing
light), check the device by operating it close to a place
where you know there is a current before touching the
conductor.
CAUTION
Protected conductors will not be detected: only metal
will be detected.
NOTES
1)
Certain walls contain metallic fire-resistant fibres.
This can create an electrical field. You can cancel
this effect by putting your hand against the wall.
2)
Rubbing or hitting the detector against the wall can
create static electricity leading to a read error.
CURRENT LOSSES
Due to the low level of current used to trigger lighting,
some detectors can appear to be faulty. A poorly
insulated conductor touching a wet wall will lead to
detection of current on the wall.
In this case, the device will indicate a potential danger
that should be checked using a voltmeter.
