– Measure the distance 10 times after another.
The deviation of the individual measurements from the average value must not exceed
±4 mm over the entire measuring section in favourable conditions. Record the meas-
urements in order to be able to compare the accuracy at a later date.
Troubleshooting – Causes and Corrective Measures
Cause
Temperature warning indicator (b) flashing; measurement not possible
The measuring tool is outside the operating
temperature range of –10 °C to +45 °C.
"Error" indication in the display
The target surface reflects too intensely
(e.g. a mirror) or insufficiently (e.g. black
fabric), or the ambient light is too bright.
The laser beam outlet 12 or the reception
lens 11 are misted up (e.g. due to a rapid
temperature change).
Measuring result not plausible
The target surface does not reflect correctly
(e.g. water, glass).
The laser beam outlet 12 or the reception
lens 11 are covered.
Obstruction in path of laser beam
The indication remains unchanged or the measuring tool reacts unexpectedly
after pressing a button
Software error
The measuring tool monitors the proper function for each measurement. When a de-
fect 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 meas-
uring tool to an authorised Bosch after-sales service.
