Operational sequence

Position before measuring cycle call
The probe must be positioned at the center of hole (MP) in the abscissa and the ordinate of
the selected measuring plane and at the calibration depth in the hole.
Axis sequence, axis direction sequence
● Paraxial, two axis directions:
● At an angle:
Position after end of measuring cycle
When calibration is complete the probe is again positioned at calibration depth in the center
of the hole.
126
Calibration starts in the positive axis direction. If _MVAR=xx0xx1 (all four directions),
calibration starts in the abscissa. This is followed by the ordinate.
The axes travel in combination acc. to starting angle _STA1 plus steps of 90 degrees.
Otherwise, the same principle as for "paraxial" applies.
