In rare instances where neither a valid Start nor Stop pattern is measurable, yet the symbol is somehow read, lines {8} and {9} are replaced by a message to that effect. The message is either:

In Screening modes, it often occurs that none of the parameters are below the Minimum Acceptable grade. In this case, the final PQA line becomes:
"All Measurements within range".
