Verifying Barcodes with PQA
A unique feature of this scanner is the 2D PQA (Print Quality
Assessment) feature, which verifies and grades several attributes of a
barcode symbol. When enabled, PQA works on all 2D symbols
including Data Matrix, PDF417, MaxiCode, Aztec, QR-Code and USPS
Postnet and Intelligent Mail. The PQA report is transmitted as a second
beep after the barcode data. Enable this feature by scanning the
barcode below.
NOTE: When verifying symbols with PQA, be sure to carefully position
the scanner directly over the barcode at an appropriate distance, such
as 5 or 6 inches. Different angles and distances may falsely lower the
grade with respect to height, width and gaps.
