Tilt sensor calibration
The user can calibrate the device’s tilt sensor. The angle
sensor is switched on by pressing the
once. Then two
measurements are taken on a flat surface. The first
measurement is taken and a note is made of the
measured angle
a
. The device is then turned through
exactly 180
°
, the second measurement is taken and a
note is made of the measured angle
b
. The value
x
to
which the device must be corrected is calculated as
follows:
x = -(a+b)/2
The calibration mode is then entered by pressing keys
and the
both at the same time for 2 seconds.
The correction value x can be entered here using the
and
keys. The entered value is stored and
implemented by pressing the
