Device Information
In the "Device Info" menu, information on the measuring tool
is provided, e.g., about the "Operation Time".
In the "Restore Settings" menu, you can restore the factory
settings.
Examples for Measuring Results
Note: In the following examples, the audio signal on the meas-
uring tool is switched on.
Depending on the size and depth of the object under the sen-
sor range, it is not always possible to positively determine
whether this object is "live" or voltage-free. In this case, the
?
symbol will appear 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.
Steel Bar (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 5.5 cm. The measur-
ing 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 measuring 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 measuring
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 measuring 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.
Cause Corrective Measure
Batteries empty Replace batteries
Batteries incorrectly in- Check if the batteries are inserted correctly
serted (wrong polarity)
Take out batteries and reinsert again
Measuring tool too warm or Wait until operating temperature range is reached
too cold
Press the start button 11 and take care that the
the surface two bottom wheels have contact with the wall
while moving the measuring tool; in case of uneven
walls, position a thin piece of cardboard between
the wheels and the wall
Measuring tool has been Press the start button 11 and move measuring tool
moved to quickly slowly over the wall
Wait until operating temperature range is reached
Wait until operating temperature range is reached
Measuring tool switches off automatically. If possi-
ble, eliminate the interfering radio waves, e.g.
WLAN, UMTS, radar, transmitter masts or micro-
waves, then switch the measuring tool on again.
