4.6.3.4 Presentation Centering
Use Presentation Centering to narrow the scanner’s field of view when it is in
the stand to make sure the scanner reads only those bar codes intended by
the user. For instance, if multiple codes are placed closely together,
Presentation Centering will insure that only the desired codes are read.
To adjust centering when the scanner is hand-held,
see Centering .If a bar code
is not touched by a predefined window, it will not be decoded or output by the
scanner. If Presentation Centering is turned on by scanning Presentation
Centering On, the scanner only reads codes that pass through the centering
window you specify using the Top of Presentation Centering Window, Bottom
of Presentation Centering Window, Left, and Right of Presentation Centering
Window bar codes. 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 Bar Code 1 passes through he centering window, it
will be read. Bar Code 2 does not pass through the centering window, so it will
not be read.
Note: A bar code 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.
