Mea. Width Example for Verifying Line Width
Mea. Width (Measure Width) is an OptiSureAOI feature that can be used in tandem with the Arrow Check Point or
Arrow Check Line commands to measure the width of a predefined line, compare that measurement to subsequent
dispenses (for either one section of the line or the complete line), and then, depending on the user-specified
parameters, determine if the dispense is acceptable. If the dispense does not meet the specified criteria, the system
takes the action specified in the Arrow Check Point or Arrow Check Line command.
PREREQUISITES
To learn how to use this feature, draw a line on a sheet of white paper and use it as a workpiece template.
