Place the measuring tool onto the wall and move it over the
wall the direction of travel (see "How it works (see figure B)",
page 17)The measuring results are shown on the dis-
play (16) after a minimum measuring path of 10 cm. To ob-
tain accurate measuring results, move the measuring tool
slowly over the entire area you believe to be occupied by an
object in the wall.
If you lift the measuring tool away from the wall during the
measuring process, or do not use it (movement, press of
button) for longer than 2 min, the last measuring result ob-
tained remains on the display. The message <Hold> appears
on the display for the sensor range (c). Place the measuring
tool against the wall again, move it again or press the start
button (11) to begin a new measuring process.
If the LED (17) lights up red, there is an object within the
sensor range. If the LED (17) lights up green, there is no ob-
ject within the sensor range. If the LED (17) flashes red,
there is a live object within the sensor range.
Before drilling, sawing or routing into walls, refer to
u
other sources of information to ensure that you elim-
inate hazards. Since the measuring results can be influ-
enced by ambient conditions or the wall material, there
may be a hazard even though the indicator does not indic-
ate an object within the sensor range (the LED (17) lights
up green).
Display elements (see figure A)
If there is an object within the sensor range, it will appear on
the display inside the sensor range (c). Depending on the
size and depth of the object, the measuring tool may be able
to identify its material. The object depth (l) from the nearest
edge of the detected object is displayed in the status bar.
Note: Both the object depth indicator (l) and the material
property indicator (m) relate to the object shown in black on
the sensor screen.
The object material indicator (m) can show the following
properties:
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
– ? Material property unknown N
S
The live cable indicator (n) can show the following proper-
ties:
1 609 92A 4G1 | (28.08.2018)
– Live
Note: No further property is displayed for live ob-
jects.
0 cm
– ? Unclear whether live or not
Note: Three-phase power cables may not be recognised as
live cables.
High relative humidity (>50 %) can significantly limit the
measuring tool's ability to detect the property "live".
Location of objects
To locate objects, moving the measuring tool once over the
measuring path is sufficient.
Next
If you do not find an object, repeat the movement perpendic-
ular to the original measurement direction (see "How it
works (see figure B)", page 17).
To identify the exact location of a detected object and to
mark the object, move the measuring tool back over the
measuring path.
(1)
When an object appears in the centre below the centre
line (k) on the display (16), as in the example, you can mark
it roughly with the top marking aid (1). This marking will only
be accurate if the object is straight and positioned exactly
vertically, as the sensor area is located slightly below the top
marking aid.
To mark the object accurately on the wall, move the measur-
ing tool to the left or right until the found object is located
below an outer edge. When the found object is, for example,
shown in the centre of the display (16) below the dashed
right-hand line (g), you can mark it accurately using the right
marking aid (3).
The course of a detected object in the wall can be determ-
ined by covering several measuring paths one after the other
(see figure I) (see "Examples of measuring results",
page 20). Mark and connect each of the measurement
points.
Press the start button (11) to delete the display of a detec-
ted object at any time and to start a new measurement.
