Auto-Scaling

The purpose of auto-scaling is to ensure an accurate
determination of pixel size for measurement and for scaling
inspection algorithms. Once set, camera scaling should not need
to be adjusted. If a different scaling is required raise or lower
the camera, re-focus, and then perform auto scaling.
Always ensure the camera is well focused before scaling.
1
Load a board in the sj5000.
2
Pick a fiducial on the board whose presence score is above
900. (Refer to the Engineering Manual for details on fiducial
training.)
From the Tools menu click the Camera folder.
3
Click Automatic in the Scaling area.
4
The gantry will start moving in the X and Y directions and
locate the fiducial for each position it goes to. This allows the
determination of the physical pixel size of the system.
