Select "Edge ratio used(%)".]
The menu for setting "Edge ratio
used" appears in the upper left of
the screen. The screen window can
be checked.
Default: 80 (%)
When "Edge ratio used" is 100, all the detected edges are indicated with "
○
"(light blue). It shows that they
are used for detecting the virtual circle. Decrease the value of Edge ratio used and run the test. The mark
for the edges unused for the virtual circle changes to "
×
" (red), and the line showing the virtual circle
comes closer to the circumference. After determining the value, press the CANCEL key.

Select "Execution Mode".
This parameter is effective when a part of a circle is out of the inspection area due to the position shift
of the object.
[Speed First] (Default)
If a part of the circle is out of the inspection area, the number of detected edge coordinates may reduce or
a different spot from the edge of the target circle may be detected. As a result, the correct virtual circle
may not be detected or the center of the detected virtual circle may not be correctly detected.
[Accuracy First]
If setting the mode to "Accuracy First", the inspection area will be adjusted to the central coordinate of a
virtual circle after the detection, and the virtual circle will be detected again. In other words, the position
adjustment is performed by the checker itself.
However, the number of detection of virtual circle in "Accuracy First" mode is more than "Speed First"
mode, and so the inspection time is longer.
