Mea. Width Example for Dispense Width Adjustment
Mea. Width (Measure Width) is an OptiSureAOI feature that can be used in tandem with the Arrow Check Point,
Auto Speed Setup, and Auto Speed commands to specify the desired width for a line and then cause the system to
automatically adjust the speed of the dispenser to maintain that desired line width for subsequent dispenses.
PREREQUISITES
To learn how to use this feature, draw two lines of different thicknesses on a sheet of white paper and use it as a
