It is recommended that this parameter be set to the mark diameter plus
3mm. For example, when the mark diameter is 1mm, set this parameter to
“4mm” as shown below.
If other marks (such as resist, screen print, other patterns) exist in this
search area, make the Search Area setting smaller.

Note
A recognition error may occur due to environmental conditions such as illumination. In
such cases, enter a larger value than previously used for the “Tolerance” parameter in the
Vision Info. sub-window, or set the tolerance to 100%, then perform “VISION TEST” in
the Adjust Assistant and enter the obtained data on the area and perimeter. (The mark
area and perimeter values are displayed after VISION TEST as shown below.) Return the
tolerance to the original value after the data is obtained.
