Distance 2 edges

This means that the distance L of two edges parallel to an axis at a workpiece, e.g.: Slot, rib,
or step, can be determined in one of the axes X, Y or Z and their center set as reference
point in a ZO.
2 measuring points are possible, P1 and P2.
Approaching the workpiece
Position the probe in front of the edge, first at P1 and after completion of this measurement
at P2.
Enter details in input form
• Selection of the ZO.
• Select axis X, Y, or Z and measurement direction at P1.
• Select the measuring direction at P2.
• Enter the set position of the two edges for the selected ZO.
Result
Measurement is performed automatically at P1 with the set measuring feed as soon as you
press "NC Start". After successful measurement, the measured value is stored internally and
the "P1 stored" softkey that was previously switched inactive is activated.
After manual positioning at measuring point P2 and with softkey "P1 stored" switched active,
pressing "NC Start" starts measurement of the 2nd measuring point P2 in the selected
measuring axis. After successful measurement, softkey "P2 stored" is activated, and the 2nd
measured value is stored.
A vertical "Calculate" softkey is then displayed. After this softkey is pressed, the distance
and the distance center between the 2 measuring points in the selected measuring axis and
the selected offset calculation are calculated. The offset is activated at the same time if it is
the active ZO.
Display and correction
After the offset calculation has been successfully completed, the frame components of the
selected ZO are re-displayed so that the calculated center of the measured edge distance
