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.

4.3 Adjust Assistant commands
This operation checks whether the parameter settings are correct. For
parameters which are unspecified, the optimal values can be obtained by
performing “VISION TEST” here. The following adjustment procedure is
explained for cases where the “Mark Type” parameter in the Mark Type
Info. sub-window is set to “Fiducial”.
1 Select the mark data.
Move the cursor to the data you want to check on the Mark Info.
