1) depending on planes
The following additional parameters are also valid:
_VMS, _CORA, _TSA, _FA, _PRNUM, _EVNUM and _NMSP
_CORA only relevant for monodirectional probe.
With _TSA, the difference of the angle is monitored and this value is additionally traversed to
_STA1 with intermediate positioning at an angle. _TSA has the dimension unit degrees in
this case!
NOTICE
Precise angle definition requires a minimum surface finish at least at the measuring points.
The distances between the measuring points must be selected as large as possible.

Meaning
Angle measurement and ZO determination, positioning at an angle
from measuring point to measuring point
Angle measurement with differential measurement and ZO
determination,
positioning at an angle from measuring point to measuring point
Angle measurement and ZO determination, paraxial positioning
from measuring point to measuring point in the offset axis
Setpoint (axis position) at measuring point 1 in the meas. axis
(for _MVAR=105 and _MVAR=1105 only)
Setpoint angle
Measuring axis: 1 (abscissa), offset axis: 2 (ordinate)
Measuring axis: 2 (ordinate), offset axis: 1 (abscissa)
Measuring axis: 1 (abscissa), offset axis: 3 (applicate)
Measuring axis: 2 (ordinate), offset axis: 1 (applicate)
Measuring axis: 3 (applicate), offset axis: 2 (ordinate)
Measuring axis: 3 (applicate), offset axis: 1 (abscissa)
Distance between measuring points P1 and P2 in offset axis
Offset of rotation about axis that is not contained in _MA
Channel axis number of rotary table
The angular offset is applied in the translation component of the
channel axis number (rotary axis).
0: positive measuring direction
1: negative measuring direction
(only for variants with paraxial intermediate positioning
_MVAR=10x10x)
0: without automatic ZO correction
>0: with automatic ZO correction
