If these softkeys are not listed, press any vertical softkey (with the
exception of "Set edge") and in the drop-down list, select the desired
measurement version.
3. Traverse the workpiece probe to approximately the center above the
rectangular pocket or the hole or for several, above the first hole to be
measured.
4. Specify whether you want "Measurement only" or in which work offset
you want to store the zero point.
 If you do make any entry in the entry field "L" length (1st geometry
5.
axis of the working plane) or "W" width (2nd geometry axis of the
working plane) of the pocket, then the axis moves with the
measuring feedrate from the starting point.
If the measuring stroke does not reach the edge, then this data
must be approximately entered. However, the measuring sequence
is then also shortened as part of the measuring distance is moved
with rapid traverse.
- OR -
 If you do not make any entry in the entry field "Øhole", then the
axis moves with the measuring feedrate from the starting point.
If the measuring stroke does not reach the edge of the hole, then
the approximate diameter must be entered. However, the
measuring sequence is then also shortened as part of the
measuring distance is moved with rapid traverse.
 Enter an angle in "Probe angle". With the probe angle you can turn
the traversing direction of the probe through any angle.
- OR -
 If you do not make any entry in the entry field "Øhole", then the
axis moves with the measuring feed from the starting point. If the
measuring stroke does not reach the edge of the hole, then the
approximate diameter must be entered. However, the measuring
sequence is then also shortened as part of the measuring distance
is moved with rapid traverse.
 In "Angle offs.", select entry "Coord. rotation".
- OR -
In "Angle offs.", select the "Rotary axis A, B, C" entry.
 Enter the setpoint angle.
 Specify the position setpoints (X1/Y1) for the center point of the
first hole.
X1 and Y1 are only active, if the "Coor. rotation" entry is selected.
