Identifying Symbol Content

To identify content or "format" aspects of a symbol, 2D PQA modes report the less than obvious characteristics of a symbol. For quality determination, 2D PQA reports those parameters that both relate directly to the print or creation process, and that also remain relatively consistent over a range of hand held reading situations.

In the 2D PQA Full Report mode, successful scans of a 2D symbol output a message similar to the following (with slight variations based upon the symbol- ogy being tested):

This is a representative PDF417 symbol

>>> PQA from HHP <<<

PDF417: 11 rows x 3 cols, 25 data & 8 chks (ECL = 2) X roughly = 0.014"

[A] < Row Height = 3.1 X

[A] < Useful Row Height = 2.5 X (82% Row)

[A]< Data Safety Margin = 100% (0 Erasures & 0 Errors)

[B]< Edge Accuracy = 59%

[C]< Print Growth = -43% of X
