– Three-phase power cables (e.g. to oven)
– Low-voltage cables (e.g. doorbell, telephone, network, smart home)
– All types of metal pipe, rod or carrier (e.g. steel, copper, aluminium)
– Reinforcing steel
– Wooden beams
– Cavities
Special measuring cases
Unfavourable conditions fundamentally impair the measuring result:
– Multi-layered walls
– Empty plastic pipes and wooden beams in cavities and lightweight partition walls
– Objects lying at an angle in the wall
– Metal surfaces and moist areas; if in a wall, these may be displayed as objects under
certain conditions (e.g. high moisture content).
Please note that concrete requires several months to dry out completely.
– Cavities in a wall; these may be displayed as objects
– Proximity to devices that generate strong magnetic or electromagnetic fields, e.g. mo-
bile phone base stations or generators
Before drilling, sawing or routing into walls, refer to other sources of informa-
u
tion to ensure that you eliminate hazards. Since the measuring results can be influ-
enced by ambient conditions or the wall material, there may be a hazard even though
the indicator does not indicate an object within the sensor range.
Change the wall type
Always set the appropriate wall type for best possible measuring results. To do this, re-
peatedly press the left-hand (14) or right-hand arrow button (7) until the required wall
type is displayed. Press the red start button (16) to accept the selection.
The maximum measuring depth is 8 cm. Any deviations from this value are described in
the individual wall types and views.
Wall Type <Brick / Universal>
The <Brick / Universal> wall type is suitable for most applications in solid masonry or
other homogeneous materials. It displays plastic pipes and metal objects as well as elec-
trical and other cables. Cavities in masonry or empty plastic pipes with a diameter of less
than 2 cm may not be displayed.
