Putting Into Operation - Bosch D-TECT 100 Operating Instructions Manual

Detectable objects:
– Plastic pipes (e.g. water pipes, empty pipes)
– 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)
– Metal of all types (e.g. steel, copper, aluminium)
– Hollow space
– Wood
Measurements possible in:
– Concrete/reinforced concrete
– Masonry blocks (brick, porous concrete, foam concrete, pumice con-
crete)
– 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 and wood in hollow spaces and light construction
walls
– 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, possibly
only the first boundary layer (e.g. hollow space behind the wall cover-
ing) 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.

3 by pressing the "mode" button 8 (duration approx.1 min).
The explanation can be restarted at any time as long as the
shown at the bottom left on the display by pressing the "mode" button
8. Pressing the "start" button 6 stops the explanation and measuring

The unit method of operation ensures relia-
ble detection of only those objects running
transverse to unit movement direction.
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.
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.
