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.
