• 4410/4710: Hold the imager 5.0 in (12.7 cm) for LR models, 2.0 in (5.1 cm) for the HD, and 7.0 in (17.8 cm) for the LX from the bar code symbol. This distance is measured from the imager's front window to the reading surface.
be held several degrees below the normal position to avoid specular reflections. • When testing, attempt to minimize as much movement of the imager as possible. Excessive movement can cause variability in PQA results. • It is best to take multiple reads of the symbol, comparing the PQA results to form a better indication of the overall symbol quality.
2D PQA Reporting Full Report Hand Held Products 2D PQA reporting can be enabled in two different modes: Full Report or Screening. If you are using Quick*View, you can enable Full Report, a listing of all of a symbol's identifying information, measurements, and corresponding grades, by...

While the details are explained below, this general format includes: • the encoded data (the usual output message) in the first line. • a banner " >>> PQA from Hand Held Products <<<" identifying the start of the 2D PQA report.

{7} lists the Data Safety Margin, which is the ratio of the unused error correc- tion words to the recommended (!) number of such words. Data Safety Mar- gin can exceed 100%, when the ECL is higher than the minimum recommended, or be limited to 50% or lower, even with perfect printing, when the ECL is below minimum.

{3} identifies the Symbology, 4-STATE (British, or KIX, Canadian, Japanese, or Australian), and also lists this symbol's size and allowed range of mea- sured width. {4} lists the Bar Sequence, "A" representing Ascending bars, "D" representing Descending bars, "T" representing Tracker (short) bars, and "H" represent- ing tall bars that both ascend and descend.
Parameter Interpretation Average Bar/Gap Width Average Bar or Inter-Bar Gap Widths are the average of such dimensions measured across an entire postal symbology. A low average bar width or inter- bar gap width grade indicates print conditions that expand or shrink the apparent size of the dark elements, threatening to make the narrow bars or spaces disappear.
Data Safety Margin Data Safety Margin is the ratio of the unused error correction codewords to the recommended number of error correction codewords. A low Data Safety Margin indicates a symbol that is close to reading failure and can be improved by improving the printing, correcting the cause of bad or missing symbol characters (e.g., spots, voids), or by raising the Error Correction Level (ECL).
Mask Pattern/Masking Mask Pattern/Masking is a specific part or characteristic of QR Code where a process is used to provide a more evenly balanced number of light and dark modules to reduce the occurrence of arrangements of adjoining modules that might interfere with efficient processing of a symbol's image.
Useful Row Height Useful Row Height is the measured Row Height times the Codeword Yield. A low Useful Row Height usually indicates print conditions where rows interfere with their adjacent neighboring rows, creating a dead band of wasted scanning in between. Useful row height scales these interfering rows to the printed row height, giving more leeway to symbols printed with above minimum row heights (e.g., 4.0 X).

The unit will communicate in RS-232 mode, allowing it to work with Quick*View through an appropriate serial cable. To convert the imager back to keyboard wedge communication, cycle the power. 4600g/4800i 4410/4710 (all three bar codes must be used in sequence) 2 - 2 Quick*View...
Using the Quick*View Software Upon startup, the Quick*View splash screen appears for approximately three seconds. Quick*View will then attempt to establish communications with the Imager. If Communication Cannot Be Established This message appears if communication cannot be established: Quick*View defaults to com 1 as the communications port. If you have plugged the Imager into another com port, you must Cancel out of this message.
Scan Data Window Once successful communication has been established, you can scan codes and display the bar code data in a window. Select View - Scan Data Window. As you scan bar codes, the data appears in the Serial Scan Data Window. You can alter the font in this window by using the Font button, or clear all data in the window with the Clear button.
