ort Error Model Equations
In addition to the errors removed by accuracy enhancement, other systematic errors exist
due to limitations of dynamic accuracy
, test set switch repeatability
, and test cable stability
.
These, combined with random errors
, also contribute to total system measurement uncertainty
.
Therefore, after accuracy enhancement procedures are performed, residual measurement
uncertainties remain.
