Press the "4 circular spigots" softkey.
- OR -
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 or circular spigot, or for several, above the first spigot to
be measured.
4. Specify whether you want "Measurement only" or in which work offset
you want to store the zero point.
 Enter the infeed value in "DY" to determine the measuring depth.
5.
 In field "L" enter the length (1st geometry axis of the working plane)
and in field "W" the width (2nd geometry axis of the working plane)
of the spigot.
- OR -
 Enter the approximate diameter of the spigot into "Øspigot".
 Enter an angle in "Probe angle". With the probe angle you can turn
the traversing direction of the probe through any angle.
- OR -
 Enter the approximate diameter of the spigot into "Øspigot".
 Enter the infeed value in "DY" to determine the measuring depth.
 In "Angle offs.", select entry "Coor. rotation" or "Rotary axis A, B,
C".
 Enter the setpoint angle.
 Enter the position setpoints (Z0/X0) for the center point of the first
spigot.
The setpoint angle refers to the 1st axis of the working plane (X/Y
plane).
The input fields for the setpoint positions are only active if you
selected the angle offset via coordinate rotation.
- OR -
 Enter the approximate diameter of the spigot into "Øspigot".
 Enter the infeed value in "DY" to determine the measuring depth.
 In "Angle offs.", select entry "No", or in "Angle offs." select entry
"Yes" if you want to align using coordinate rotation.
 Specify the setpoint angle if you selected entry "Yes" for "Angle
offs."
 Enter the setpoint positions Z0 and X0 to determine the center
point of the circuit on which the center points of three spigots lie.
The setpoint angle refers to the 1st axis of the working plane (X/Y
plane). This input field only appears if you specified "Yes" for "Angle
offs."
- OR -
