– When the measuring tool moves away from the object, the object centre
indicators (a) will turn off, the amplitude in the measuring indicator (b) will decrease
and the audio signal will sound more slowly.
Objects are only displayed roughly the first time you move over the centre and boundar-
ies of the object.
In order to locate the exact centre of an object, move the measuring tool back in the dir-
ection of the object without lifting it off until the object centre is indicated again (the ob-
ject centre indicators (a) will light up).
In order to locate the boundaries of the object with greater precision, continue to move
the measuring tool in a straight line from the object's centre until the light-up ring (1) is
no longer lit up red.
The marking hole (2) is located above the central measuring point. If necessary, you can
use this to mark the centre or boundaries of the object.
Note: After you have marked an object through the marking hole (2) (e.g. with a pencil),
you will need to start a new measurement because the measurement may be impaired by
the pencil.
The type of object found is indicated on the display:
(h)
Non-magnetic metal, e.g. copper pipe
(g)
Magnetic metal, e.g. rebar
(f)
Live, e.g. power lines
(e)
Non-metallic, e.g. wooden beams
Information about Detecting Live Cables
– The cable must be live. You should therefore connect electricity consumers (e.g.
lights, appliances) to the electricity cable you are trying to find. Switch on the electri-
city consumers to ensure that the electricity cable is live.
– The 50–60 Hz signal from the electricity cable must be able to reach the measur-
ing tool. If the cable is in damp walls (e.g. > 50 % humidity), behind metallic foil (e.g.
thermal insulation) or in an empty metal pipe, the signal will not reach the measuring
tool and you will not be able to find the cable.
– The measuring tool must be sufficiently earthed. To do this, hold it firmly (without
gloves) by the gripping surface (8). Make sure that you are in good contact with the
floor. Insulating shoes, ladders or platforms may compromise your contact with the
floor. The floor must also be earthed in order for live cables to be detected.
