Obstruction in the path of the laser beam.
The laser point must be fully on the target
surface.
The measuring tool monitors for correct operation in every measure-
ment. If a defect is detected, the display will indicate only the symbol
shown opposite. In this case, or if you are unable to rectify an error us-
ing the corrective measures above, send the measuring tool to Bosch
customer service via your dealer.
Checking the accuracy of the measuring tool
You can check the accuracy of the measuring tool as follows:
– Choose a measuring section of approx. 3–10 m in length that is permanently un-
changed, the exact length of which is known to you (e.g. room width, door opening).
The measuring section must be indoors, and the target surface of the measurement
must be smooth and reflect well.
– Measure the section ten times in succession.
The deviation between the individual measurements and the mean value must not ex-
ceed ±2 mm. Record the measurements in order to be able to compare the accuracy
later on.
