Coefficients List Screen Features
Correlations between measurement process error sources are accounted for by using the Correlation Coefficients
List Screen, which is accessed by clicking Correlations on the Measurement Process Uncertainty
Correlating Error Sources
measurement error sources to correlate with one another are listed in the Variable 1 column.
Clicking the Variable 2 column activates a drop-down list of the possible components for Variable 2.
Click the down arrow of this list and click the Variable 2 component of interest. This will select Variable 2 and link it to Variable 1.
The correlation coefficient for the two
error sources can be entered directly or copied and pasted from an
external file via the Edit menu. External application files
can be opened from within AccuracyRatio via the Run
External Application Screen, which is accessed by selecting Run
on the menu.
is repeated until all necessary coefficients have been entered for correlated
error source pairs. Clicking OK will accept the entries and returns
you to the Measurement Process Uncertainty Worksheet. The specified
correlation coefficients are automatically accounted for in computing the total
