• 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 there is a fixed or known, you can enter it. This will limit the number of characters
read. The read will fail if it does not match this value. If the string changes, leave this field
blank or an asterisk (* for wild card) to report every read. You can use a question mark (?) for a
single character “wild card” or an asterisk (*) for a multiple character “wild card”.
The Padlock button
allows you to lock the Value, so it does not change while you change
parameter settings or move or resize the Region.
• Locator – makes the tool follow the Locator, and follow the part. Select a locator (by number)
to follow, or select “X” to disconnect the tool from the locator, or make the tool stay in a fixed
position in the image area.
• Channel – select a color class, or select “Brightness” for (monochrome) intensity.
• Auto label position – puts the label (OCR1) beside the tool in the display. Clear the check box
to move the label to another location (or with the Properties box closed, drag the label).
• Max. – maximum number of characters read. Limiting the number of characters read can in-
crease speed.
• Ignore white space – hides space separating characters. This is especially useful for vertical
character strings or multiple line strings. In the sample (under “Using the Font Editor”), “Ig-
nore white space” changes the reported string from 2442 8903 to 24428903.
• Required score – sets a minimum acceptance or threshold for the score of each match. Potential
matches that do not meet this minimum are discarded or not reported.
• Rotate – direction of the characters (left to right, top to bottom, etc.) Positive counter-clock-
wise. Use this to change the direction characters are sampled or read. Changes the direction in
the Font Editor. For a Torus or Annulus Region: 0= scan or read counter-clockwise, 180= scan
clockwise.
• Unwrap – limit or increase the read or sample distance around a Torus Region. 360 is one com-
plete revolution. 720 is two complete revolutions. Using a number greater than 360 will repeat
the area located at the beginning of the unwrap scan, and include characters that may be split by
a 360 scan.
