When no button on the measuring tool is pressed
for approx. 5 minutes and when no objects are de-
tected, the measuring tool automatically switches
off to save the battery.
Switching the Display Illumination On/Off
The display illumination can be switched on/off
with display-illumination button 6.
Switching the Audio Signal On/Off
The audio signal can be switched on/off with the
audio signal button 7. When the audio signal is
switched off, indication a appears on the display.
Method of Operation (see figures A–B)
The measuring tool checks the base material of
sensor area 12 in measurement direction A to the
max. detection depth (see "Technical Data"). Ob-
jects are detected 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 meas-
urement, the contact pads 11 must always have
contact to the surface.
Measuring Procedure
Position the measuring tool on/against the surface
being detected, and move it in direction B. When
the measuring tool comes closer to an object, the
amplitude in measuring indicator i increases and
ring 1 lights up yellow; when it is moved away from
the object, the amplitude decreases. Measuring in-
dicator i indicates the maximal amplitude above
the centre of the object; ring 1 lights up red and an
audio signal sounds. For small or deeply embed-
ded objects, ring 1 can continue to light up yellow,
while there is no audio signal.
 Wide objects are not indicated by the illumi-
nated 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. The fine scale j is automatically activat-
ed in all operating modes. Fine scale j indicates a
full amplitude when the object is below the centre
of the sensor or when the maximum amplitude of
measuring indicator i is reached. In the operating
modes "Drywall" and "Metal", the indication
"CENTER" k lights up additionally.
Wider objects in the base material are detected
through a continuous, high amplitude of measuring
indicators i and j. Ring 1 lights up yellow. The du-
ration of the high amplitude corresponds approxi-
mately with the object width.
When very small or deeply embedded objects are
being sought and measuring indicator i reacts only
slightly, move the measuring tool repeatedly over
the object in horizontal and vertical direction. Pay
attention to the amplitude of fine scale j, and when

in operating mode "Drywall" and "Metal", addi-
tionally to the "CENTER " k indication, which will
then allow for precise detection.
 Before drilling, sawing or routing into a wall,
protect yourself against hazards by using oth-
er information sources. As the measuring re-
sults can be influenced through ambient condi-
tions 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 1 lit green).

Operating Modes

The best measuring results are achieved through
selection of the operating modes. The maximal de-
tection depth for metal objects is achieved in the
operating mode "Metal". The maximal detection
depth for "live" conductors is achieved in the oper-
ating mode "Power cable". The selected operating
mode can be recognized at any time via the green
illuminated operating-mode indication 4.
Drywall
The operating mode "Drywall" is suitable for de-
tecting wood or metal objects in drywalls.
Press button 10 to activate the operating mode
"Drywall". The operating-mode indication 4 above
button 10 lights up green. As soon as the measur-
ing tool is positioned against the base material to
be detected, ring 1 lights up green and signals op-
erational 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
Notes: In the operating mode "Drywall", other ob-
jects, apart from wood and metal objects and "live"
conductors are also detected, such as plastic tub-
ing filled with water. For such objects, the indica-
tion c for non-metal objects is indicated in display
3.
Nails and screws in the base material may cause a
wooden beam to be indicated as a metal object on
the display.
When display 3 indicates a continuously high am-
plitude of measuring indicator i and fine scale j, re-
start the measuring procedure again by positioning
the measuring tool at a different location on the
base material.
When the illuminated ring 1 does not signal opera-
tional readiness when positioning the measuring
tool on the base material being detected, the meas-
uring tool cannot properly detect the base material.
– Press and hold button 10 until the illuminated
ring lights up green.
