Troubleshooting – Causes and Corrective Measures
Cause
Temperature indicator b flashes; measurement not possible
The measuring tool is outside the oper-
ating temperature range from – 10 °C
to + 50 °C (in the function continuous
measurement up to +40 °C).
Battery indication a is indicated
Battery voltage decreasing
(measurement still possible)
Battery indication a flashes, measurement not possible
Battery voltage too low
The indications "ERROR" and "–––––" are indicated in the display
The angle between the laser beam and
the target is too acute.
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 16 or the recep-
tion lens 17 are misted up (e.g. due to
a rapid temperature change).
The indication "ERROR" flashes at the top in the display
Addition/Subtraction of measured
values with different units of measure
Unreliable measuring result
The target surface does not reflect
correctly (e.g. water, glass).
The laser beam outlet 16 or the recep-
tion lens 17 are covered.
Accuracy Check of 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. 1 to 10 metres; its length must be precisely known (e.g. the
width of a room or a door opening).
• Measure the distance 10 times after another.
The measuring error must not amount to more than a maximum of ±4 mm.
Keep a record of the measurements in order to compare the accuracy at a
later time.

The measuring tool monitors the correct function for each
measurement. When a defect is determined, only the sym-
bol shown aside flashes in the display. In this case, or when
the above mentioned corrective measures cannot correct
an error, have the measuring tool checked by an after-sales
service agent for Bosch power tools.
Corrective Measure
Wait until the measuring tool has
reached the operating tempera-
ture
Replace batteries
Replace batteries
Enlargen the angle between the
laser beam and the target
Work with the laser target plate
20 (accessory)
Wipe the laser beam outlet 16
and/or the reception lens 17 dry
using a soft cloth
Only add/subtract measured
values with the same units of
measure
Cover off the target surface
Make sure that the laser beam
outlet 16 or the reception lens 17
are unobstructed
