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
Aimer
Delay , page 96, 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 bar-
code scanners.)
Note: To adjust centering when the scanner is in a stand, see Presentation Centering (page
4-87).
Single Code Centering
Scan Single Code Centering 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 , Left , and Right of Centering Window bar-
codes.
