1 UncertaintyAnalyzer contains a built-in graphical user-interface for designing and analyzing system modules and computing uncertainty propagation from system input through system output.

2 The mixed option allows for the use of a mean value computed from sample values combined with a user specified standard deviation and sample size obtained from a prior sample of data that characterizes the repeatability uncertainty of a measurement process.

3 Built-in SpecMaster tool for computing tolerance limits from complex equipment specifications using VB Script programming language.

4 Database containing measurement area and units consistent with NIST Special Publication 811. Editable via user interface.

5 Relational database for storing and retrieving instrument identification information, tolerancing data, and other operating and manufacturer specifications.

6 A variety of reporting levels are available including summary reports and "drill-down" reports for complete communication of analysis results.

7 Options for changing report fonts, selecting which reports to print, including or excluding notes or comments, and including or excluding charts, plots and other graphics (if available). All reports can also be previewed prior to printing.
