Bosch Power Tools

– 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

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.

Cause

Corrective Measure

Temperature warning indicator (b) flashing; measurement not possible

The measuring tool is outside the operating 
temperature range of – 10 ° C to + 45 ° C.

Wait until the measuring tool has 
reached the operating temperature

“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.

Work with the laser target plate 

13

 (ac-

cessory)

The laser beam outlet 

12

 or the reception 

lens 

11

 are misted up (e. g. due to a rapid 

temperature change).

Wipe the laser beam outlet 

12

 and/or 

the reception lens 

11

 dry using a soft 

cloth

Measuring result not plausible

The target surface does not reflect correctly 
(e. g. water, glass).

Cover off the target surface

The laser beam outlet 

12

 or the reception 

lens 

11

 are covered.

Make sure that the laser beam outlet 

12

 or the reception lens 

11

 are unob-

structed

Obstruction in path of laser beam

Laser point must be completely on tar-
get surface.

The indication remains unchanged or the measuring tool reacts unexpectedly 
after pressing a button

Software error

Remove the batteries and start the 
measuring tool again after reinserting 
them.
