Troubleshooting – Causes and
Corrective Measures
Cause
Temperature indicator b flashes; measurement
not possible
The measuring tool is out-
side the operating tempera-
ture 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 19 or
the reception lens 20 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 dif-
ferent units of measure
Unreliable measuring result
The target surface does not
reflect correctly (e.g. water,
glass).
The laser beam outlet 19 or
the reception lens 20 are
covered.
The measuring tool monitors the correct
function for each measurement. When a
defect is determined, only the symbol
shown aside flashes in the display. In
this case, or when the above mentioned
corrective measures cannot correct an
error, have your dealer forward the measuring tool to
the BTI after-sales service.

Corrective Measure
Wait until the measuring
tool has reached the
operating temperature
Replace batteries
Replace batteries
Enlargen the angle
between the laser beam
and the target
Use laser viewing
glasses 22 (accessory)
Wipe the laser beam out-
let 19 and/or the recep-
tion lens 20 dry using a
soft cloth
Only add/subtract meas-
ured values with the
same units of measure
Cover off the target sur-
face
Make sure that the laser
beam outlet 19 or the
reception lens 20 are
unobstructed

Accuracy Check of the Measuring Tool
The accuracy of the measuring tool can be checked as
follows:
• Select a permanently unchangeable measuring sec-
tion 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 r3 mm. Keep a record of the measure-
ments in order to compare the accuracy at a later time.

Maintenance and Service

Maintenance and Cleaning

Store and transport the measuring tool only in the sup-
plied protective case.
Keep the measuring tool clean at all times.
Do not immerse the measuring tool into water or other
fluids.
Wipe off debris using a moist and soft cloth. Do not use
any cleaning agents or solvents.
Maintain the reception lens 20 in particular, with the
same care as required for eye glasses or the lens of a
camera.
If the measuring tool should fail despite the care taken
in manufacturing and testing procedures, repair should
be carried out by an authorized after-sales service cen-
tre for BTI power tools.
In all correspondence and spare parts orders, please
always include the 6-digit article number given on the
nameplate of the measuring tool.
In case of repairs, send in the measuring tool packed in
its protective case 23.
