Granit XP User Guide 99
Example: In the example below, the white box is the centering window. The centering window
has been set to 20% left, 30% right, 8% top, and 25% bottom. Since Barcode 1
passes through the centering window, it will be read. Barcode 2 does not pass
through the centering window, so it will not be read.
Note: A barcode needs only to be touched by the centering window in order to be read. It
does not need to pass completely through the centering window.
Scan Centering On , then scan one of the following barcodes to change the top,
bottom, left, or right of the centering window. Then scan the percent you want to
shift the centering window using digits from the
Programming Chart, beginning on
page 289, then Save . Default Centering = 40% for Top and Left, 60% for Bottom
and Right.
