Switching the Display Illumination On/Off
The display illumination can be switched on/off with display-illumination button 2.
Switching the Audio Signal On/Off
The audio signal can be switched on/off with the audio signal button 4. When the
audio signal is switched off, indication l appears on the display.
Method of Operation (see figure A)
The measuring tool checks the base material of sensor area 11 in measurement
direction z to the max. detection depth (see "Technical Data"). Objects are de-
tected that differ from the material of the wall.
Always move the measuring tool in a straight line over the surface applying slight
pressure, without lifting it off or changing the pressure. During measurement,
the contact pads 10 must always have contact to the surface.
Measuring Procedure
Position the measuring tool on/against the surface being detected, and move it
in direction of axis x and y. When the measuring tool comes closer to an object,
the amplitude in measuring indicator f increases and ring 9 lights up yellow;
when it is moved away from the object, the amplitude decreases. Measuring in-
dicator f indicates the maximal amplitude above the centre of the object; ring 9
lights up red and an audio signal sounds. For small or deeply embedded objects,
ring 9 can continue to light up yellow, while there is no audio signal.
Wide objects are not indicated by the illuminated ring or the audio signal
throughout their complete width.
To localise the object more precisely, move the measuring tool repeatedly (3x)
back and forth over the object.
Wider objects in the base material are detected through a continuous, high am-
plitude of measuring indicator f. Ring 9 lights up yellow. The duration of the high
amplitude corresponds approximately with the object width.
When very small or deeply embedded objects are being sought and measuring
indicator f reacts only slightly, move the measuring tool repeatedly over the ob-
ject in horizontal (axis x) and vertical (axis y) direction.
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 and the illuminated ring 9 lit green).

Operating Modes

The best measuring results are achieved through selection of the operating
mode. The maximal detection depth for metal objects is achieved in the operat-
ing mode "Metal". The maximal detection depth for non-metal objects is
achieved in the operating mode "Drywall". "Live" conductors are detected in
any operating mode.
Drywall
The operating mode "Drywall" is suitable for detecting wood or metal objects as
well as "live" conductors in drywalls.
Press button 1 to activate the operating mode "Drywall". The indicator h lights
up. As soon as the measuring tool is positioned against the base material to be
detected, ring 9 lights up green and signals operational readiness.
In the operating mode "Drywall" all object types are detected and indicated:
– Non-metal, e.g. a wood beam
– Magnetic, e.g. reinforcing steel
– Non-magnetic, but metal, e.g. copper pipe
– "Live", e.g. a "live" conductor
