Centering
Use Centering to narrow the scanner’s field of view to make sure that when the scanner is
hand-held, it reads only those barcodes intended by the user. For instance, if multiple codes
are placed closely together, centering will insure that only the desired codes are read.
(Centering can be used in conjunction with
, page 47, for the most error-free
operation in applications where multiple codes are spaced closely together. Using the Aimer
Delay and Centering features, the scanner can emulate the operation of older systems, such
as linear laser barcode scanners.)
Note:
To adjust centering when the scanner is in a stand, see

to target the barcode closest to the center of the image. Singling
out a barcode in this manner increases scanning accuracy when there are multiple barcodes
close together.

Custom Centering
Use the following settings to customize your centering window. If a barcode is not touched by
a predefined window, it will not be decoded or output by the scanner. If centering is turned
on by scanning
Centering On
, the scanner only reads codes that pass through the centering
window you specify using the
Top of Centering Window
,
Bottom of Centering Window
,

,
and
Right of Centering Window
barcodes.
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.
