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.
Note: To adjust centering when the scanner is hand-held, see
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 scan-
ning
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 the 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.
