NOTE
A recognition error may occur due to environmental conditions such as illumination. In such cases, enter a larger
value than previously used for"Tolerance" of the Vision parameters, or set the tolerance to 100%, then perform
the vision test in the Mark Adjust mode and enter the obtained data on the area and perimeter. (The mark area and
perimeter values are displayed after the vision test is complete.) Return the tolerance to the original value after the
data is obtained.
