Operation
Protect the measuring tool against moisture
and direct sun light.
Do not subject the measuring tool to
extreme temperatures or variations in
temperature. As an example, do not leave it
in vehicles for longer periods. In case of large
variations in temperature, allow the measuring
tool to adjust to the ambient temperature before
putting it into operation.
Hold the measuring tool only at the intended
grip area 10, so as not to influence the
measurement.
Use or operation of transmitting systems,
such as WLAN, UMTS, radar, transmitter
masts or microwaves, in the close proximity
can influence the measuring function.
The measuring values can be impaired
through certain ambient conditions.
These include, e.g. the proximity of devices
that produce strong electric, magnetic or
electromagnetic fields, moisture, metallic
building materials, foil-laminated insulation
materials or conductive wallpaper or tiles.
Therefore, also observe other information
sources (e.g. construction plans) before drilling,
sawing or routing into walls, ceilings or floors.
Switching On and Off
Check the measuring tool before each use. In
the following cases, safe function can no longer
be ensured:
– The measuring indicator h constantly
deflects, even though you hold the device in
the air.
– The measuring indicator does not deflect,
even though you keep a finger in the sensor
area.
– The device has visible damage or loose
components inside the measuring tool.
Before switching the measuring tool on,
make sure that the sensor area 14 is not
moist. If required, dry the measuring tool using
a soft cloth.
If the measuring tool was subject to an
extreme temperature change, allow it to
adjust to the ambient temperature before
switching on.
To switch on the measuring tool, press the On/
Off button 6
.
To switch off the measuring tool, press the On/
Off button 6
again.
When no button on the measuring tool is
pressed for approx. 5 minutes and when
no objects are detected, the measuring tool
automatically switches off to save the battery.
Switching the Audio Signal
On/Off
The audio signal can be switched on/off with
the audio signal button 5
. When the audio
signal is switched off, the display 3 indicates the
information c.
Method of Operation
(see figure B)
The measuring tool checks the base material
of the sensor area 14 in measurement direction
A. Objects are detected that differ from the
material of the wall.
Always move the measuring tool over the base
material applying light pressure, without lifting it
off or changing the pressure.
The measuring tool can be moved in any
direction B.
Operation Modes
As soon as the measuring tool is switched on,
you can switch between different operating
modes.
By selecting the operating modes, you can
adjust the measuring tool to different wall
materials and, if required, suppress unwanted
objects.
If the wall material is not known, you should
begin with the Universal mode.
The selected operating mode is indicated by the
illuminated button.
Drywall (default mode)
The operating mode “Drywall” is suitable
for detecting joists, metal supports,
electrical lines and cables in drywalls
(wood, plasterboard, etc.). Water-filled plastic
pipes are also indicated. Empty plastic pipes are
normally not detected. The maximum measuring
depth is 2.36-in (6 cm).
Universal
The operating mode “Universal”
is suitable for most applications in
masonry. Metal objects, water-filled
plastic pipes, electrical lines and cables are
indicated. Cavities in building brick or empty
