• 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."

• Enter the approximate diameter of the spigot into "Øspigot".
• Enter the infeed value in "DZ" to determine the measuring depth.
• In "Angle offs.", select entry "Yes" if you want to align using
coordinate rotation or select in "Angle offs." the entry "No".
• Enter the setpoint angle.
• Enter the setpoint positions X0 and Y0 to determine the point of
intersection of the connecting lines between the spigot center points.
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."
4. Press the <CYCLE START> key.
This starts the automatic measuring process. The tool automatically
probes four points in succession of the rectangular or spigot outer wall
or the outer wall of the first spigot if several spigots are to be measured.
After the measurement has been successfully completed, the center of
the spigot is determined and the "P1 stored" softkey becomes active.
5 If you are measuring several spigots, then move the tool approximately
to the center of the second, third, and fourth spigot and press the
<CYCLE START> key.
