PORTABLE SHOULD DESCRIBE WHERE YOU CAN MEASURE. NOT WHAT YOU HAVE TO GIVE UP.
Measurement confidence is earned by evidence.
For a portable system, the useful questions are specific:
What reference was used? Which operating conditions and measurement ranges were evaluated? How repeatable were the results? What happened during transient operation? Was the complete sampling, flow and data configuration assessed? Can the reported results be traced to the underlying measurements?
Correlation is part of that conversation. It also needs context: agreement, bias, response behavior and the conditions of the comparison all matter.
Across this series, we have explored one principle: field measurement depends on a complete engineering system and evidence suited to its intended use.
The lab sets the standard. Our engineering challenge is to take that confidence into the field.
