Bosch Power Tools
Corrective Measure
With your free hand, touch the wall at a distance of
20 –30 cm from the measuring tool to ground the
wall.
Add voltage to the cable, for example by turning on
light switches assigned to it. The detection of ca-
bles with AC voltages outside of the range
110 –240 V, 50 –60 Hz is not reliably possible.*
The scanning depth is dependent on the building
material and may be less than the maximum scan-
ning depth.*
Use the measuring tool to locate the metal pipe.
Hold the measuring tool firmly without gloves. Do
not stand on insulating ladders or scaffolding. Do
not wear insulating footwear.
A reliable detection is not possible with metallic or
moist building materials (e.g. at high air humidity).*
The scanning depth is dependent on the building
material and may be less than the maximum scan-
ning depth.*
The scanning depth is dependent on the building
material and may be less than the maximum scan-
ning depth.*
Keep your distance from devices emitting strong
electric or magnetic fields (e.g. computers, switch
mode power supplies).
