Centering

Use Centering to narrow the scanner's field of view to make sure the scanner
reads only those bar codes 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
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 scan-
ners.)
In the example below, the gray area is the full scanner field of view and the white
area is the centering window. Bar Code 1 will not be read, while Bar Code 2 will
be.
