metal or reinforcing steel in
concrete
Solid metal objects on the
back of the wall

Corrective measures
The detection depth depends on the building material
and may be less than the maximum detection depth.
Detection will not be accurate in the presence of metallic
building materials or building materials that are too
damp (e.g. if the humidity is too high).
Corrective measures
Start a recalibration via the <Reset> submenu.
Metal objects spaced too closely together cannot be de-
tected separately.
In the presence of metallic building materials (e.g. foil-
laminated insulation materials, heat conduction plates),
reliable detection is not possible.
In the presence of solid metal objects (e.g. radiators),
reliable detection is not possible.
Start a recalibration via the <Reset> submenu.
The detection depth depends on the building material
and on the object and may be less than the maximum de-
tection depth.
Corrective measures
Touch the wall with your free hand at a distance of
20−30 cm from the measuring tool in order to earth the
wall.
