Data coverage note: The complete row-by-row dataset remains in the original workbook. This page retains the tested applications, record counts, full observed error ranges and representative low/mid/high-pressure records. No source value has been estimated.
Conclusion
The measurements above characterize the observed auto-stop and settled-pressure behavior. A formal pass/fail claim is made only where the source report supplies an acceptance limit and verdict.
Frequently Asked Questions
Why are only representative rows displayed?
Repeating every near-identical cycle would obscure the engineering result. The full observed error envelope and test counts are retained, while the workbook remains the authoritative raw record.
What is the accuracy delta?
It is the difference defined in the source worksheet between the settled pressure and the preset target.
