display 8 appears in the device display
(Fig. B).
If there is an object, for which the search is
activated, in the vicinity of the detector,
several bars appear at first on the intensity
display. As proximity to the search object in-
creases, the number of bars increases on the
intensity display (Fig. C).
If the detector is exactly over the search
object, a continuous signal tone sounds.
In the case of a search for a power line, the
voltage sign ( )
7 also appears in addition
to the intensity display.
Tips on measurement
Incorrect measurements can occur depending
on the nature of the examined wall. Check
therefore before every measurement the posi-
tion of a known wooden or metal beam, of a
known void or a known power line. If these
are not detected by the device, the substrate
is not suitable for a search with this device.
Please note that power lines can also be lo-
cated as metal or as beams. Always use the
additional voltage search, so that you can
exclude any incorrect interpretations.
Please note that metal beams are also detected
in the Beam search „STUD“ function. If you
find a beam and you want to be sure that it is
not a metal beam (or for example a water pipe),
use the additional Metal search „METAL“.
Depending on the wall thickness and mate-
rial, it is possible that the detector may signal
a finding, before it is over the material. In this
case mark the start and end of the signalled
