Regularly check the accuracy of the grade meas-
urement by carrying out a reversal measurement or
with the spirit levels of the measuring rail.
In case of greater deviation, the measuring tool
must be recalibrated. For this, press and hold the
grade measurement button
3
. Follow the directions
on the display.
To end the “Measuring rail” operating mode,
switch the measuring tool off and remove it from
the measuring rail.

The measuring tool is out-
side the operating tempera-
ture range from – 10 °C to
+ 50 °C (in the function con-
tinuous measurement up to
+40 °C).
Wait until the meas-
uring tool has
reached the operat-
ing temperature

The angle between the laser
beam and the target is too
acute.
Enlarge the angle
between the laser
beam and the target
The target surface reflects
too intensely (e.g. a mirror)
or insufficiently (e.g. black
fabric), or the ambient light
is too bright.
Use a laser target
plate
The laser beam outlet

or
the reception lens

are
misted up (e.g. due to a rap-
id temperature change).
Wipe the laser

Indication “>60°” or “<–60°” on the display
The inclination measuring
range for the measuring
mode and/or the reference
plane has been exceeded.
Carry out the meas-
urement within the
specified angle
range.
“CAL” and “ERROR” indication in the display
The calibration of the grade
measurement was not car-
ried out in the correct se-
quence or in the correct po-
sitions.
Repeat the calibra-
tion according to
the instructions on
the display and in
the operating in-
structions.
The surfaces used for the
calibration were not accu-
rately aligned (horizontal or
vertical).
Repeat the calibra-
tion on a horizontal
or vertical surface; if
required, check the
surface first with a
level.
The measuring tool was
moved or tilted while press-
ing the button.
Repeat the calibra-
tion and hold the
measuring tool in
place while press-
ing the button.
Battery charge-control indicator (g), tempera-
ture warning (k) and “ERROR” indication in the
display
Temperature of the measur-
ing tool not within the allow-
able charge-temperature
range
Wait until the
charge-tempera-
ture range is
reached.
Battery charge-control indicator (g) and
“ERROR” indication in the display
Battery charging voltage not
correct
Check if the plug-in
connection has
been established
correctly and if the
battery charger is
operating properly.
When the unit sym-
bol is flashing, the
battery is defective
and must be re-
placed by a BTI af-
ter-sales service.
Battery charge-control indicator (g) and clock
symbol (f) in the display
Charge duration clearly too
long, as charging current
too low.
Only use the origi-
nal BTI charger.
Measuring result not plausible
The target surface does not
reflect correctly (e.g. water,
glass).
Cover off the target
surface
