Tolerance
■ Select [Tolerance]
The value set here determines how much the area of a detected fiducial may
differ from the area which is specified in the teach data (see FIGURE 6 -9)
That area is defined by the
[Area of Fiducial] parameter, and limited by the
[Smallest Enclosing Rectangle] setting.

NOTE: Common settings range from 10 to 15% on good fiducials; fiducials of less
quality may require a higher value.
