Calibration
Additional Notes about Calibration
The following conditions apply to the reader’s calibration process. Some of these items
are noted at various points throughout this section, or in other sections of the reader’s
documentation.
1. If Window of Interest Framing is enabled, the WOI will be set to full frame when
calibration begins. If WOI Framing is disabled, the current WOI configuration will be
used for the Search Pass .
2. Image Processing Mode will not be altered during calibration.
3. Thresholding Mode will be set to Adaptive during calibration. At the completion of a
successful calibration, the threshold mode will remain set to Adaptive regardless of its
previous setting. Otherwise, the value will revert back to its original state. This is so
the reader can continue to decode after calibration is finished.
4. If Symbol Type is enabled for calibration ( Autodiscriminate ), then Interleaved 2 of 5 Range
Mode Status (Interleaved 2 of 5) <K472> will be enabled. This allows variable-length
Interleaved 2 of 5 symbols to be decoded. If an Interleaved 2 of 5 symbol is decoded
during calibration, then code length # 1 will be set to the decoded symbol length at the
end of calibration. Otherwise, the symbol lengths will be restored to their original
configurations.
5. Pharmacode is not calibrated.
6. The symbol size, dimension, and orientation parameters of the No Symbol / Bad
Symbol and Symbol Qualification command <K718> will be updated if calibration is
successfully completed.
7. All symbol types that were enabled before calibration will still be enabled after calibration.
For example, if Data Matrix ECC 200 was enabled before calibration, and the calibration
routine was performed on a Code 128 symbol, then after calibration is completed both
Data Matrix ECC 200 and Code 128 will be enabled.
8. Calibration does not modify the global Composite status <K453> . The global Composite
status must be configured properly before calibration.
9. If the user requires calibration of a stacked symbology <K482> , <K483> , or <K484> ,
that symbology must be enabled and configured appropriately before calibration.
10. The Search process will use the configurable Window of Interest for image captures.
However, when the search process is completed, the WOI will be reduced to include
only the symbol of interest and some additional boundary area.
