Switching Off; Measuring Process - Bosch D-tect 150 SV Professional Notice Originale

How it works (see figure B)
The measuring tool checks
the base material of the
sensor area (9) in the meas-
A
urement direction A up to the
displayed measuring depth.
You can only carry out a
measurement while the
measuring tool is being
9
moved in travel direction B
and with a minimum measur-
ing path of 10 cm. Always
B
move the measuring tool in
a straight line while apply-
B
ing light pressure to hold it
against the wall, so that the
wheels remain in contact with the wall. Objects are de-
tected that differ from the material of the wall. The ob-
ject depth is indicated on the display, as well as the ma-
terial of the object, where possible.
Optimum results are achieved when the measuring path is at
least 40 cm and the measuring tool is moved slowly across
the entire area to be checked. The tool's function allows for
reliable detection of the nearest edges of objects that run
transverse to the direction of movement of the measuring
tool.
For this reason, always move crosswise over the area to
be checked.
If multiple objects are located over each other in the wall, the
display will indicate the object whose surface is nearest to
the measuring tool.
The properties of the detected objects as shown on the dis-
play (16) may differ from the actual object properties. In
particular, very thin objects appear thicker on the display.
Larger, cylindrical objects (e.g. plastic pipes or water pipes)
may appear narrower on the display than they actually are.
Detectable objects
– Plastic pipes (e.g. water-filled plastic pipes, such as un-
derfloor or wall heating pipes, etc. with a diameter of at
least 10 mm, or empty pipes with a diameter of at least
20 mm)
– Electrical cables (regardless of whether live or not)
– Three-phase power cables (e.g. to oven)
– Low-voltage cables (e.g. doorbell, telephone)
– All types of metal pipe, rod or carrier (e.g. steel, copper,
aluminium)
– Reinforcing steel
– Wooden beams
– Cavities
Possible measurements
– In concrete/reinforced concrete
– In masonry (bricks, porous concrete, expanded concrete,
pumice, calcareous sandstone)
– In lightweight partition walls
– Beneath surfaces such as plaster, tiles, wallpaper, par-
quet, carpet
Bosch Power Tools
– Behind wood, plasterboard
Special measuring cases
Unfavourable conditions fundamentally impair the measur-
ing result:
– Multi-layered walls
– Empty plastic pipes and wooden beams in cavities and
lightweight partition walls
– Objects lying at an angle in the wall
– Wet wall material
– Metal surfaces
– Cavities in a wall; these may be displayed as objects
– Proximity to devices that generate strong magnetic or
electromagnetic fields, e.g. mobile phone base stations
or generators
Start-up
Switching on/off
Before switching on the measuring tool, ensure that
u
the sensor area (9) is dry. If necessary, use a cloth to
dry the measuring tool.
If the measuring tool has been exposed to a significant
u
change in temperature, leave it to adjust to the ambi-
ent temperature before switching it on.
Switching on
– To switch on the measuring tool, press the on/off but-
ton (15) or the start button (11).
– The LED (17) lights up green and the start screen ap-
pears on the display (16) for 4 s.
– If you do not carry out a measurement or press a button
on the measuring tool, it switches off automatically after
5 min. You can change this <Cut-off time> in the Settings
menu (see "<Cut-off time>", page 20).

Switching off

– To switch off the measuring tool, press the on/off but-
ton (15).
– When the measuring tool is switched off, all settings se-
lected in the menus are retained.
Switching audio signal on/off
The audio signal can be switched on and off using the audio
signal button (13). In the Settings menu, select the signal
types in the <Tone signal> sub-menu (see "<Tone signal>",
page 20).

Measuring process

Switch on the measuring tool. The default display screen ap-
pears on the display (16).
