The Cylinder Centering Thread Scan strategy for the Cylinder Auto Feature performs a thread scan by maintaining the probe centered within the thread. When you use this strategy, the diameter of the probe tip must exceed the size of the valleys in-between the threads in order to prevent probe shanking.
This strategy is supported only on B4 and B5 Leitz controllers.
The following properties are available:

To take two hits at slightly different points on the thread to determine the best place to start the scan, select this check box. It picks the point that is deepest into the thread.
