c. Move the mouse over the image in the Work Area.
Click, release, move the mouse and click again, to
draw a Region shape where you want to read a bar-
code. Refer to the tip window. The Region is labeled
(Barcode1). When the Barcode tool is selected, you
can move and resize the Region.
If the code is part of the stamp or mold that forms your part, the code should move very little, and
your Region can be very close to the size of the code. If the code is part of a separate label or
etching process, you need a larger Region shape to allow for variation in the location of the code.
d. When you hover the cursor over the edge of the tool, the Region outline turns red, and a
message appears telling you to “Right-click to edit.”
e. Right-click on the highlighted Region outline. A Barcode Properties box opens. In this box
you can: rename the measurement, set the code type (System), and other parameters.
Code The code value read, or compare code to a fixed value.
Grade the quality of the barcode.
Enable – check this box to report a measurement and pass or fail the part on this measurement;
or clear this box to not report a measurement and not pass or fail the part on this measurement.
Value – If the barcode should always be the same value, type the expected barcode beside “Ex-
pression”. The code will fail if it does not match this value. If the barcode changes, leave an
asterisk (* for wild card) in this field, to report any read. You can use a question mark (?) for a
single character “wild card” or an asterisk (*) for a multiple character “wild card”. For exam-
ple; 123?? for any 5 character code starting with 123, or 123* for any code of any length start-
ing with 123.
The Padlock button
allows you to lock the Value, so it does not change as you change
parameter settings or move the ROI.
