Bosch PLR 30 C Original Instructions Manual page 33

Cause
Batteries/rechargeable batteries are too
weak.
No Bluetooth® connection
There is a problem with the Bluetooth®
connection.
The measuring tool monitors correct functioning in every measure-
ment. If a defect is detected, the display will indicate only the symbol
shown opposite. In this case, or if the above-mentioned corrective
measures cannot rectify an error, submit the measuring tool to the
Bosch after-sales service via your dealer.
Accuracy check of the measuring tool
You can check the accuracy of the measuring tool as follows:
– Choose a measuring section of approx. 3 to 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.
