generates the 180 degrees reversal before the second measurement. The mean value is
calculated from both measured values.
A correction of the work offset (WO) is only possible when measuring without reversal (1-point
measurement).
Requirements
● The probe must be calibrated in the measuring direction.
● The probe of type 710 or 580 must be active.
● The cutting edge position can be 5 to 8 and must be suitable for the measurement task.
Starting position before the measurement
The probe should be positioned opposite the surface to be measured, above the turning center.
Position after the end of the measuring cycle
The probe is at a distance of the measuring path (DFA) from the measuring surface, above
the turning center.
When "Travel under the center of rotation" is selected, after the end of the measuring cycle,
the probe is at a distance of the measuring path (DFA) from the measuring surface, below the
center of rotation.
