Total System Specifications
When you use specifications to compare equipment, be sure to establish an error budget that
accounts for all possible measurement uncertainty. Sensor calibration is an integral part of
validation, and total system accuracy should include potential error from the recorder, as well
as the temperature reference and traceable standard. Since all component errors are additive to
the total system, every potential error is significant. A summary of the error budget for a
validation system after sensor calibration with type T thermocouples, used at steam and dry
heat with a Kaye HTR-400 as temperature reference and a Kaye IRTD-400, is listed below.
