Circle - ipf electronic opti-check Technical Documentation Manual

12.2.2 Circle

This feature check determines the position, the diameter and the roundness of a circle in comparison to a
reference circle that is taught in. The search area for a circle is defined by selecting a minimum inner circle
and a maximum outer circle. Both the position and the diameter of the detected circle are compared with
switching points.
This feature check supports external Teach. The switching points for the diameter are adjusted as a
percentage to the current measured value. The thresholds for the distance remain unchanged as the newly
programmed circle is adopted as a reference and the distance reverts to zero.

Select the shape of the field of view. A circular ring and a circular ring sector can be chosen.

Adjust the field of view by holding the left mouse button depressed.
In this example, the diameter, position and roundness of a hole are determined by measuring from the outer
circle towards the inner circle. Both results appear directly on the display:
