Measuring Procedure

Switch the measuring tool on. The "standard start display" ap-
pears on display 16.

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, the last measured result remains on the dis-
play. "Hold" appears on the sensor-range indicator c. When
the measuring tool is placed against the wall again, moved on
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.
 Before drilling, sawing or routing into a wall, protect
yourself against hazards by using other information
sources. As the measuring results can be influenced
through ambient conditions or the wall material, there may
be a hazard even though the indicator does not indicate an
object in the sensor range (LED 17 lit green).
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 allowable
drilling depth l to the upper edge of the found object is indicat-
ed in the status line.
Note: Both the indication of the allowable drilling 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:
– Magnetic, e.g. reinforcing steel
N
S
– N Non-magnetic, but metal, e.g. copper pipe
S
– Non-metal, e.g. wood or plastic

– ? ? N Material property unknown

Bosch Power Tools
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
?
0 cm
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
4
sufficient.
When no object has been found, repeat the motion perpen-
6
dicular to the initial measuring direction (see "Method of Op-
eration (see figure B)", page 16).
Next
For precise localisation and marking of an object, move the
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.
The direction of a found object in a wall can be determined by
carrying out several offset measurements one after another
(see figure I and "Examples for Measuring Results", page 19).
Mark and connect the respective measuring points.
By pressing the start button 11, the display of the objects
found can be deleted at any time and a new measurement
started.
