Mea. Point To Line Example

Mea. Point to Line is an OptiSureAOI 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.

# Click Step Reference Image

• Jog the camera to a location on the

• Click SET MARK, then drag to position

the red box (item 1) over the line.

center of the red box (item 2) and then

enter the desired values for Width and

Height (20 and 60 in this example).

save the mark, then click TEMPLATE

when the Template Match window

center of the mark and enter Width

and Height values (20 and 480 in this
