How Effective Is Accuracy Enhancement?
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.

The uncorrected performance of the analyzer is sufficient for many measurements.
However, the next three illustrations show the improvements that can be made in
measurement accuracy by using a more complete calibration routine. See
