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 object, identification of
the material is possible. The allowable drilling
depth l to the upper edge of the found object is
indicated in the status line.
Note: Both the indication of the allowable drill-
ing depth l as well as the material property m re-
fer to the object pictured black in the sensor.
The indication of the object material m can rep-
resent the following characteristics:
– Magnetic, e.g. reinforcing steel
N
S
– Non-magnetic, but metal, e.g. copper
N

pipe
– Non-metal, e.g. wood or plastic

The indication of "live" wires n can represent
the following characteristics:
– "Live"
Note: For "live" objects, no further character-
istic is displayed.
– ? 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 mo-
tion perpendicular to the initial measuring direc-
tion (see "Method of Operation", page 21).
For precise localisation and marking of an ob-
ject, 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 precise,
when the object is positioned exactly vertical in
the wall, as the sensor range is located some-
what below the top marking aid.

For exact marking of the object on the wall,
move the measuring tool left or right until the
found object is positioned below one of the out-
er edges. When the found object, as an example,
is indicated centrical below the dashed right-
hand line g in display 16, you can mark it pre-
cisely with the right marking aid 3.
The direction of a found object in a wall can be
determined by carrying out several offset meas-
urements one after another (see figure I and
"Examples for Measuring Results", page 26).
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.
Changing the Operating Modes
Changing between different operating modes is
possible with selection buttons 10 and 12.
– Briefly press selection button 10 to select
the next operating mode.
– Briefly press selection button 12 to select
the previous operating mode.
By selecting the operating modes, you can adapt
the measuring tool to different wall materials
and suppress insignificant objects (e.g. hollow
spaces in brickwork). The current setting is al-
ways shown in the operating-mode indication h
of the display.
