The measuring tool monitors the proper function for each measurement.
When a defect is detected, all indicators on the display flash. In this case,
or when the corrective measures listed above cannot correct the error,
have your dealer forward the measuring tool to an authorised Bosch after-
sales service.
Checking the Measuring Tool
The accuracy of the measuring tool can be checked as follows:
– Select a permanently unchangeable measuring section with a length of
approx. 3 to 10 metres; its length must be precisely known (e.g. the
width of a room or a door opening). The measurement should be car-
ried out under favourable conditions, meaning, the measuring dis-
tance must be indoors and the target surface for the measurement
must be smooth and reflect well.
– Measure the distance 10 times after another.
Under favourable conditions, the deviation of the individual measure-
ments from the mean value must not exceed ±3.5 mm (max.) over the
complete measuring distance. Log the measurements, so that you can
compare their accuracy at a later point of time.
