● The lateral surfaces of the probe cube must be aligned parallel to the machine axes Z1, X1
(axes of the plane).
● The approximate positions of the switching surface of the probe regarding the machine or
workpiece zero must be entered before calibration starts in the general setting data (see
Commissioning Manual
measurement in turning").
These values are used for automatic approach to the probe with the calibration tool and
their absolute value must not deviate from the actual value by more than the value in
parameter TSA.
The probe must be reached within the total path 2 · DFA.
