Measuring variants
Measuring cycle CYCLE976 permits the following calibration variants which are specified via
parameter _MVAR.
● Calibration in hole (axes of the plane)

Note
When _MVAR=xx1x0x calibration is only performed in one direction. It is not possible to
determine position deviation or calculate probe ball.
Result parameters
Measuring cycle CYCLE976 returns the following values in data block GUD5 for calibration:
