tive wallpaper or tiles. Therefore, also observe other in-
formation sources (e.g. construction plans) before
drilling, sawing or routing into walls, ceilings or floors.
Method of Operation (see figure B)
The measuring tool checks the
base material of sensor area 9
in measurement direction A to
A
the displayed measuring
depth. Measurement is possi-

ble only during movement of

the measuring tool in the di-
rection of travel B and for a

measuring distance of at least
10 cm. Move the measuring
tool in a straight line with

light pressure over the wall
so that the wheels remain in
B
contact with the wall. Ob-
jects are detected that dif-
fer from the material of the wall. The allowable drilling
depth and, if possible, the object material, are indicated
on the display.
Optimum results are achieved when the measured distance is
at least 40 cm and the measuring tool is moved slowly over
the entire location to be checked. The tool's method of opera-
tion ensures reliable detection of outer object edges that run
transverse to the measuring tool's movement direction.
Therefore, always move crossways over the area to be
checked.
If several objects are located one over the other in the wall,
the object that is indicated in the display is the one nearest to
the surface.
The representation of the properties of detected objects in
the display 16 can deviate from the actual object properties.
This applies particularly for very thin objects, which are repre-
sented thicker in the display. Large cylindrical objects (e.g.
plastic or water pipes) can appear in the display smaller than
they actually are.
Detectable Objects
– Plastic pipes (e.g. water-carrying plastic pipes, as used in
floor/wall-heating systems, with at least 10 mm in diame-
ter; empty pipes with at least 20 mm in diameter)
– Electrical wiring (independent of whether carrying voltage
or not)
– Three-phase mains wiring (e.g. to the stove)
– Low-voltage wiring (e.g. for door bell, telephone
– Metal pipes, bars, beams of any type (e.g. steel, copper,
aluminium)
– Reinforcing steel
– Wooden beams
– Hollow spaces
Measurements possible
– In brickwork (bricks, porous concrete, foam concrete, aer-
ated concrete, lime-sand brick)
– In concrete/reinforced concrete
– In light construction walls
1 609 92A 26X | (4.3.16)
– Under surfaces such as stucco, tiles, wallpaper, parquet
flooring, carpet
– Behind wood, gypsum board
Special Measuring Cases
Based on the measuring priniciple, unfavourable conditions
can influence the measuring result, for example:
– Multi-layered walls
– Empty plastic pipes and wood beams in hollow spaces and
light construction walls
– Objects running inclined in walls
– Metal surfaces and damp areas; in walls, these can possi-
bly be indicated as an object (e.g. when the water content
is high).
Please observe that concrete requires several months to
dry completely.
– Hollow spaces in a wall; these can be indicated as objects
– Closeness to equipment that generates strong magnetic or
electromagnetic fields, e.g. radio base stations or genera-
tors

Initial Operation

 Protect the measuring tool against moisture and direct
sun light.
Switching On and Off
 Before switching the measuring tool on, make sure that
the sensor area 9 is not moist. If required, dry the mea-
suring tool using a soft cloth.
 If the measuring tool was subject to an extreme tem-
perature change, allow it to adjust to the ambient tem-
perature before switching on.
Switching On
– To switch on the measuring tool, press the On/Off button
15 or the start button 11.
– LED 17 lights up green and the start display is indicated for
4 s on display 16.
– When no measurement is carried out and no button is
pressed for 5 minutes, the measuring tool switches off au-
tomatically. This "Cut-off time" can be changed in the
"Settings" menu (see "Cut-off Time", page 18).
Switching Off
– To switch the measuring tool off, press the On/Off button
15.
– When switching off the measuring tool, all settings are re-
tained in the menus.
Switching the Audio Signal On/Off
The audio signal can be switched on/off with the audio signal
button 13. This "Tone signal" can be changed in the "Set-
tings" submenu (see "Tone Signals", page 19).
