Requirements
● The probe must be active as tool.
● Probe type:
– 3D multi probe (type 710)
– Mono probe (type 712)
– L probe (type 713)
● The probe length must be known in the program for collision-free positioning of the
workpiece probe and entered in the tool offset memory.
● The sphere radius must be known exactly and entered in the tool data. For example, this
can be implemented using a previous calibration in the ring or on the sphere (valid for type
710, 712).
● The calibration surface is perpendicular to the measuring axis or tool axis.
Starting position before the measurement
The probe must be positioned opposite to the calibration surface.
The distance between the probe and calibration surface should be approximately the same as
the selected measurement path (DFA).
Position after the end of the measuring cycle
According to the measuring direction (X, Y, Z), the distance between the probe in AUTOMATIC
operation and the calibration surface is the same as the distance of the selected measurement
path (DFA). In JOG operation, the start position is approached again.

Note
L probe application (type 713)
Calibration in +Z (for towing measurement) is possible with the L probe.
The basic alignment of the L probe boom is toward +X (offset angle = 0). If the probe
boom is to be aligned in a different direction in the measuring program, this can be
performed through a rotation around the tool axis (e.g. ROT Z = 90).
