EXAMPLES FOR MEASURING RESULTS
Note: In the following examples, the audio signal on
the measuring tool is switched on.
Depending on the size and depth of the object under
the sensor area, it is not always possible to
positively determine whether this object is "live" or
voltage-free. In this case, the
in indicator n.
"Live" Wire (see figure C)
A "live", metal object (e.g. a power cable) is within the
sensor range. The object depth is 1.5 cm. The
measuring tool emits the warning signal for "live"
conductors as soon as the power cable is detected
by the sensor.
Magnetic Object (see figure D)
A magnetic object (e.g. a steel bar) is within the
sensor range. Further objects are also located to the
left and right, outside of the sensor range.
The object depth is 8.8 cm. The detection tool emits
an audio signal.
Copper Pipe (see figure E)
A metal object (e.g. a copper pipe) is within the
sensor range. The object depth is 4 cm. The
detection tool emits an audio signal.

Plastic or Wooden Object
(see figure F)
A non-metal object is within the sensor range. The
object is plastic or wooden, and close to the surface.
The detection tool emits an audio signal.
Large Surface
(see figure G)
A metal, large surface (e.g. a metal plate) is within
the sensor range. The object depth is 2 cm. The
detection tool emits an audio signal.
Many Unclear Signals
(see figures H–I)
When many objects are shown in the standard start
display, the wall probably consists of many hollow
spaces. To broadly block out the hollow spaces,
switch to the "Metal" operating mode.
When there are still too many objects being shown,
carry out several height-offset measurements and
mark the detected objects on the wall.
Offset marks are an indication for hollow spaces,
whereas marks on a line indicate an object.
