Putting Into Operation - Bosch wallscanner D-TECT 100 Instructions D'emploi

Objects are found reliably only when they
All manuals and user guides at all-guides.com
run transversely to the direction of
movement of the unit.
Therefore, always move crossways
over the area to be checked.
Objects that are considerably larger than
the unit can also be indicated with parallel
movements.
The indication of the unit is optimised for
the highest possible safety for drilling.
Drilling can be performed to the maximum
drilling depth determined.
If several objects are located one over the other in the wall, the object
is indicated in the display that is nearest to the surface.
Detectable objects:
– Metal of all types (e.g. steel, copper, aluminium)
– Plastic pipes (e.g. water pipes, empty pipes)
– Wood (e.g. beams)
– Electrical wiring (independent of whether carrying voltage or not)
– Three phase mains wiring (e.g. to the stove)
– Extra-low voltage wiring (e.g. telephone, door bell)
– Hollow space
Measurements possible in:
– Concrete/reinforced concrete
– Masonry blocks (brick, porous concrete, foam concrete, pumice
concrete)
– Light construction walls
– as well as under surfaces such as stucco, tiles, wallpaper, parquet,
carpet
Special Measuring Cases
Under unfavourable conditions, the unit cannot detect certain objects
as a result of the principle involved, for example:
– Empty plastic pipes in hollow spaces are not detected.
– Metal surfaces and damp surfaces with high water content cannot
be penetrated.
– Damp areas in a wall can possibly be indicated as an object (e.g.
for high water content).
– For walls made up of several layers, e.g. with wall covering, possi-
bly only the first boundary layer (e.g. hollow space behind the wall
covering) is indicated.
– Hollow spaces in a wall are indicated as objects.
– Large cylindrical objects (e.g., plastic or water pipes) can appear in
the display smaller than they actually are.
