Decoding Levels - Datalogic QuickScan Lite QW2100 Product Reference Manual

Decoding Levels

Decoding Levels are used to configure a bar code symbology decoder to be very aggressive to
very conservative depending on a particular customer's needs.

There are many factors that determine when to change the decoding level for a particular sym-
bology. These factors include spots, voids, non-uniform bar/space widths, damaged labels, etc.
that may be experienced in some bar code labels. If there are many hard to read or damaged
labels that cannot be decoded using a conservative setting, increase the decoding level to be
more aggressive. If the majority of labels are very good quality labels, or there is a need to
decrease the possibility of a decoder error, lower the decoding level to a more conservative level.
Product Reference Guide
Choosing Level 1 results in a very conservative decoder at the expense of not being able to
read poorly printed or damaged labels.
Choosing Level 5 results in a very aggressive decoder. This aggressive behavior allows
decoding of poorly printed and damaged labels at the expense of increasing the likelihood
of decoding errors.
Choosing Level 3, which is the default setting, allows the majority of product labels to be
decoded.
