In a horizontal attitude the probe cannot make comparative probing
measurements from opposite orientations. The measuring touch probe can be
used only for digitizing in the horizontal attitude. It is not possible to align the
workpiece in a horizontal attitude.
Warning
Be sure to enter the correct value in MP6322 for the attitude of the touch
probe. Otherwise the calculation of the maximum deflection from MP6330
may by incorrect.
Danger of breakage!
If the stylus is deflected by a distance larger than that defined in MP6330, the
blinking error message Stylus deflection exceeds max.: appears.

In MP6310, select the mean deflection depth during digitizing.
• For standard parts: Input value = 1 mm
• On parts with steep sides that are scanned at high speed:
Input value > 1 mm
With the deflection depth, the probing force of the touch probe can be
optimized.
After starting the "meander" or "contour lines" cycle, the probe moves at the
feed rate defined in MP6361 to the clearance height, and then in the working
plane to the point above the starting point. It then moves at the reduced feed
rate defined in MP6350 to the MIN point or to the first touch point:

In MP6361, enter a feed rate for rapid traverse in the probing cycle.

In MP6350, enter a feed rate for positioning to the MIN point and probing
the contour.

With MP6362, select whether the scanning feed rate is automatically
reduced if the ball tip deviates from the path.
During scanning of contour lines, the probe sometimes ends the contour line
at a point located near but not exactly at the starting point:

In MP6390, define a target window within which the probe is considered to
have returned to the starting point. The target window is a square.
Input value: Half the edge length of the square
MP6360 (probing feed rate) and MP6361 (rapid traverse in the probing cycle)
are effective in the standard probe cycles.
