Code quality grading software for fixed-mount barcode readers
Standards-Based Grading (SBG) is a software feature key that can be preloaded or activated on select DataMan fixed-mount barcode readers to grade the quality of 1D and 2D codes. SBG uses the same verification grading algorithms, calibration process, and software user interface as DataMan verifiers but does not include the fixed angle lighting required in the International Organization for Standardization (ISO) guidelines. SBG is ideal to use when existing barcode quality software, such as process control metrics (PCM), is not reliable enough, and ISO compliance is not required or possible.
Why Standards-Based Grading?
An increasing number of industries require compliance to ISO or industry application guidelines that can only be met with ISO-compliant barcode verifiers. However, not all applications are able to use ISO-compliant verification due to mounting restrictions or barcode placement.
SBG is the closest way to achieve reliable and repeatable barcode diagnostic results similar to verification without conforming to specific lighting angles, working distances, or mounting restrictions. With SBG, the reader can be calibrated to unify the camera’s measurement of reflectivity levels and all ISO quality parameters are reported.
Unlike SBG, PCM does not have a calibration process, follow the ISO grading algorithm requirements, or report every quality parameter. While PCM results can provide a good idea of code quality, the results can also vary significantly between setups and hardware used.

Auto-Generate Code Quality Reports
The SBG software platform provides visual diagnostic information to identify one-off or trending code quality issues. Codes are assigned an overall grade based on measurements of several symbology specific quality parameters using ISO grading algorithms. These parameters measure several factors that affect a barcode reader’s ability to identify and decode a code.
