For incremental calibration, the direction of
travel is specified by the sign of _FA.

1: calibration in +/- direction in 1 (abscissa)
2: calibration in +/- direction in 2 (ordinate)
3: calibration in +/- direction in 3 (applicate)
Also possible for calibration in plane:
102:
a) Calculation of center in 1(abscissa)
b) Calibrate in 2 (ordinate)
201:
a) Calculation of center in 2 (ordinate)
b) Calibrate in 1 (abscissa)
not for incremental calibration!
