Mea. Point To Line Example
Mea. Point to Line is an OptiSureAOI feature used in tandem with the Arrow Check Point command. This feature
measures the width between two specified points on a dispensed line, compares the measurement to a set of points
on a subsequent dispense, and then, depending on the user-specified parameters, determines 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 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.
