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. In the "Settings" menu, you can change the
"Cut-off time" (see "Cut-off Time", page 19).

Prev. Concrete Universal
Position the measuring tool against the wall and move it over
the wall in the direction of travel (see "Method of Operation
(see figure B)", page 16). Measured results are indicated on
display 16 after a minimum measuring distance of 10 cm. To
ensure correct measurement results, move the measuring
tool slowly and completely over the assumed object in the
wall.
If the measuring tool is lifted away from the wall during a
measurement or not operated (moving the device or pressing
a button) for more than 2 minutes, the last measured result
remains on the display. "Hold" appears on the sensor-range
indicator c. When the measuring tool is placed against the wall
again, moved, or when the start button 11 is pressed, the
measurement starts anew.
When LED 17 lights up red, an object is in the sensor range.
When LED 17 lights up green, no object is in the sensor range.
When LED 17 flashes, a "live" object is in the sensor range.
Display Elements (see figure A)
If an object is under the sensor, it will appear in the sensor
range c of the display. Depending on size and depth of the ob-
ject, identification of the material is possible. The object
depth l to the upper edge of the found object is indicated in
the status line.
Bosch Power Tools
Note: Both the indication of the object depth l as well as the
material property m refer to the object pictured black in the
sensor.
The indication of the object material m can represent the fol-
lowing characteristics:
– N Magnetic, e.g. reinforcing steel
S
– N Non-magnetic, but metal, e.g. copper pipe
S
– Non-metal, e.g. wood or plastic
Metal
– ? ? N Material property unknown
S
The indication of "live" wires n can represent the following
characteristics:
– "Live"
Note: For "live" objects, no further characteristic is dis-
played.
– ? Not definite whether "live" or voltage-free
Note: Three-phase mains wiring are possibly not detected as
"live" conductors.
Localisation of Objects
To localise objects, moving over the measuring path once is
sufficient.
When no object has been found, repeat the motion perpen-
dicular to the initial measuring direction (see "Method of Op-
eration (see figure B)", page 16).
For precise localisation and marking of an object, move the
0 cm
measuring tool back over the measuring path.

When an object is indicated centrally below the centre line k
in display 16, as in the example, you can mark it coarsely with
the top marking aid 1. This mark, however, will only be pre-
cise, when the object is positioned exactly vertical in the wall,
as the sensor range is located somewhat below the top mark-
ing aid.
For exact marking of the object on the wall, move the mea-
suring tool left or right until the found object is positioned be-
low one of the outer edges. When the found object, as an ex-
ample, is indicated centrical below the dashed right-hand line
g in display 16, you can mark it precisely with the right mark-
ing aid 3.
