Inserting/Changing The Batteries - Bosch D-tect 150 Professional Notice Originale

16 | English
Under certain conditions (e.g. electrostatic discharge or ap-
plication of electromagnetic fields), the measuring results
may be lost and it may be necessary to reset the measuring
tool by removing and replacing the batteries.

Inserting/changing the Batteries

It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
Push the locking mechanism (5) in the direction of the arrow
to open the battery compartment cover (4) and remove the
battery compartment cover. Insert the batteries/re-
chargeable batteries. When doing so, ensure that the polar-
ity is correct and corresponds to the diagram in the battery
compartment.
The battery indicator (b) in the top status bar of the dis-
play (16) indicates the state of charge of the batteries.
Note: Pay attention to the battery symbol as it changes to
ensure that you replace the batteries in good time.
If the warning message
Please change batteries
<Please change batteries>
appears on the display (16),
the settings are saved and
the measuring tool switches
off automatically. It is no
longer possible to carry out
measurements. Replace the batteries.
To remove the battery/batteries, apply pressure to the rear
end of a battery as shown in the battery compartment cover
diagram (1.). The front end of the battery is freed from the
battery compartment (2.), allowing the battery to be easily
removed.
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
Take the batteries out of the measuring tool when you
u
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage.
Operation
Protect the measuring tool from moisture and direct
u
sunlight.
Do not expose the measuring tool to any extreme tem-
u
peratures or variations in temperature. In case of
large variations in temperature, leave the measuring
tool to adjust to the ambient temperature before
switching it on. The accuracy of the measuring tool and
the functionality of the display may be compromised if ex-
posed to extreme temperatures or variations in temperat-
ure.
Do not attach any stickers or labels to the sensor
u
area (9) on the rear of the measuring tool. Metal labels
in particular will affect measuring results.

The use or operation of transmitters such as WLAN,
u
UMTS, radar, transmitter masts or microwaves in the
surrounding area may affect the measuring function.
Certain ambient conditions fundamentally impair the
u
measuring results. These include, e.g. the proximity of
devices that generate strong electric, magnetic or
electromagnetic fields, moisture, metal building ma-
terials, foil-laminated insulation materials or conduct-
ive wallpaper or tiles. Therefore, also refer to other in-
formation sources (e.g. construction plans) before
drilling, sawing or routing into walls, ceilings or floors.
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 per-
mitted drilling depth is indicated on the display, as well
as the material 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)
