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 (no audio
signal or beep and the illuminated ring 17 lit green).
Display Elements (see figure A)
If an object is under the sensor area, it will appear
in the sensor range
c
of the display. Identification
of material type depends on size and depth of
object. The object depth
l
to the upper edge of the
found object found is indicated in the status line.
Note:
Both the indication of the object depth
l
as
well as the material type
m
refer to the object
pictured black in the sensor area.
The indication of the object material
m
can
represent the following characteristics:
–
Magnetic, e.g. reinforcing steel
–
Non-magnetic, but metal, e.g. copper pipe
– Non-metal, e.g. wood or plastic
–
Material type unknown
The indication of “live” wires
n
can represent the
following characteristics:
–
“Live”
Note:
For “live” wire/conductors, no further
characteristic is displayed.
–
Not definite whether “live” or voltage free
Note:
Three-phase wiring are
possibly
not
detected as “live” conductors.
Object Detection
To detect objects, moving over the measuring path
once may be enough.
When no object is found, repeat the motion
perpendicular to the initial measuring direction
(see “Operation Instructions”, page 13).
For precise detection and marking of an object,
move the detection tool back over the
measuring path.
When an object is indicated directly below the
center line
k
in display
16
, as in the example, mark
it roughly with the top marking guide
1
. This mark
will only be precise when the object is positioned
exactly vertical in the wall, as the sensor range is
located somewhat below the top marking guide.
For exact marking of the object on the wall, move
the detection tool left or right until the found object
is positioned below one of the outer edges. When
the found object is indicated directly below the
dashed righthand line
g
in display
16
, mark it with
the right marking aid
3
.
The direction of an object found in a wall can be
determined by carrying out several offset
measurements one after another (see figure
I
and
“Examples for Measuring Results”, page 13). 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 detection tool to different wall materials. The
current setting is always shown in the operating-
mode indication
h
of the display.
Concrete
“Concrete”
is suitable for most applications in
brickwork or concrete. Plastic and metal objects
as well as electrical wiring are displayed. Hollow
spaces in brickwork or empty plastic pipes with a
diameter of less than 1” may not be displayed. The
maximum measuring depth is 3-1/8”.
Wet Concrete
The operating mode
“ Wet Concrete”
is
particularly suitable for applications in wet
reinforced concrete. Reinforcing steel, plastic and
metal pipes, as well as electrical wiring are
displayed. Differentiating between “live” and
voltage-free conductors is not possible. The
maximum detection depth is 2-3/8”.
Please note that concrete requires several months
to dry completely.
Deep Concrete
The operating mode
“Deep Concrete ”
is
particularly suitable for detecting objects
embedded
deep
in
reinforced
concrete.
Reinforcing steel, plastic and metal pipes, as well
as electrical wiring are displayed. The maximum
