Calibration of probe 1 on a surface
Workpiece probe 1 with cutting edge position SL=7 is to be calibrated on surface Z=-18 mm
in direction minus Z. The probe is inserted as tool T9, D1.
Probe lengths L1 and L2 always refer to the probe ball center and must be entered in the
tool offset memory before the measuring cycle is called, T9, D1:

Explanation of example
The surface with position Z=-18 is approached in the Z axis in the minus direction
(_SETVAL=-18, _MA=1, _MD=1).
Actual calibration starts _FA=3 mm in front of the surface. The workpiece probe is then
calibrated and ends up facing the surface again at distance _FA from it. The new trigger
value in minus Z is entered in the data of probe 1 _WP[0,1] and in the result field _OVR[ ].
The original position is approached in block N40, N50.
