The measuring tool monitors the correct operation in each measure-
ment. If a defect is detected, the display will show only the adjacent
symbol. In this case, or when the above mentioned corrective meas-
ures cannot correct an error, have the measuring tool checked by an
after-sales service agent for Bosch power tools.
Measuring tool is not
grounded.
Hold the measuring tool firmly without gloves. Do not
stand on insulating ladders or scaffolding. Do not
wear insulating footwear.
Shielding building material or
humidity too low/too high
Detection will not be accurate in the presence of
metallic building materials or building materials that
are too dry or too damp (e.g. if the humidity is too low
or too high).
Metal object is not located.
Metal object is too deep or
too small.
The detection depth depends on the building material
and on the object and may be less than the maximum
detection depth.
No wooden beams are found.
Measured section too short Start the measurement at a different place on the wall
and move the measuring tool over a larger section.
Wooden beam too deep The scanning depth is dependent on the building
material and may be less than the maximum scanning
depth.
Shielding building material or
humidity too high
Detection will not be accurate in the presence of
metallic building materials or building materials that
are too damp (e.g. if the humidity is too high).
