The Height sensor can be positioned either above or below the 0 focus height as shown in the
figures. However it should not be positioned above the level of the tray/box. In this case the
tray/box would never be detected so the Tracking Offset must be set to compensate. This
Offset then is added to the Percentage of Tray Depth to Set AF therefore degrading the focus
precision.
Fixed Exposure Value
If Fixed is selected, this sets a fixed exposure time to optimize the quality of the acquired image
Fixed Gain Value
This option is only used for testing. It should be set to Normal for regular operation.
