Measuring a spigot

You have the option to measure and align rectangular spigots, and one or more circular
spigots.
Measuring a rectangular spigot
The rectangular spigot should be aligned at right-angles to the coordinate system. By
measuring four points at the spigot you can determine the length, width, and center point of
the spigot.
Please note that the straight lines between points P1 and P2 or P3 and P4 must intersect
with one another, in order that a measurement result is displayed.
Measuring 1 circular spigot
The workpiece is located anywhere on the work table and has a circular spigot. You can
determine the diameter and center point of the spigot with four measuring points.

The tool automatically probes 4 points of the inside wall of the first hole
successively and after pressing <CYCLE START> again probes the 4
points of the inside wall of the second hole.
The angle between the line connecting the center points and the
reference axis is calculated and displayed.
With "Set WO", the center point of the first hole now corresponds to the
position setpoint. The calculated rotation is stored in the work offset.
The tool automatically probes 4 points of the inside wall of the first hole
successively and after pressing <CYCLE START> again, then the 4
points of the inside wall of the second or third hole are successively
probed.
The center point and the diameter of the circle on which the three hole
center points lie are calculated and displayed. If you selected entry
"Yes" for "Angle offs.", the angle α is additionally calculated and
displayed.
With "Set WO", the center point of the first hole now corresponds to the
position setpoint. The calculated rotation is stored in the work offset.
The tool automatically probes 4 points of the inside wall of the first hole
successively. After pressing <CYCLE START> again, the tool
automatically probes the 4 points of the inside wall of the second, third
and fourth holes.
The hole center points are connected diagonally and the intersection
point of the two connecting lines calculated and displayed. If you
selected entry "Yes" for "Angle offs.", the angle α is additionally
calculated and displayed.
With "Set WO", the intersection point now corresponds to the position
setpoint. The calculated rotation is stored in the work offset.
