Uncertainty Sidekick Pro ($295 USD) is a complete measurement uncertainty analysis application that incorporates and extends methods found in the ISO Guide to the Expression of Uncertainty in Measurement (the ISO GUM).  Uncertainty Sidekick Pro handles direct and multivariate measurements and utilizes interactive uncertainty analysis procedure checklists that access drill-down screens and worksheets that facilitate the uncertainty calculation and analysis process.


Uncertainty Sidekick Pro does not "dumb down" uncertainty analysis, does not require knowledge of statistics to use, and does not require a spreadsheet application to operate.  Uncertainty Sidekick Pro is by far the most cost-effective measurement uncertainty calculation tool for achieving compliance with ISO 17025 and ANSI/NCSL Z540.3.  Uncertainty Sidekick Pro 1.0 runs on Windows XP, 7, 8 and 10 operating systems.


Key program features are outlined below.  Detailed information and screen shots for each feature can be accessed via associated hypertext links.  For a side-by-side comparison to our Uncertainty Sidekick freeware and UncertaintyAnalyzer software click here.

Details and Screen Shot Links

Abundant On-Screen Information

  • Interactive analysis procedure checklists provide a short, structured walk-through of the basic uncertainty calculation steps for typical measurement scenarios. 

  • All screens and worksheets have access to a full-featured on-screen Help with index, content, and search capabilities for over 400 topics.


Measurement Configuration Options

  • Users can choose from a list of measurement configurations via the Measurement Configurations Screen.  

  • Selecting a measurement configuration instructs Uncertainty Sidekick Pro to de-activate screens and worksheets that are not required for the measurement uncertainty analysis.


Analysis of Direct Measurements

  • Every aspect of the measurement uncertainty analysis process can be accessed via the Main Screen

  • Main Screen menu and tool bars and measurement uncertainty analysis procedure checklist provide quick access to drill-down analysis screens and worksheets.

  • Information about the subject parameter being analyzed, key measurement process uncertainties, and the overall combined measurement uncertainty are all summarized on the Main Screen.  

Drill-down Worksheets for Analyzing Measurement Process Errors


Analysis of Type A, Type B and Type A,B Estimates

  • The measurement uncertainty estimate type is automatically determined based on user data entry.

  • Degrees of freedom are computed for all measurement uncertainty estimate types.

  • Type B error limits can be computed as a linear or root-sum-square (RSS) combination of a fixed value, % of nominal or reading, % of full scale, and % of range or other components.


Data Importing

  • Measurement units, measuring equipment and samples of measurement data can be imported into Uncertainty Sidekick Pro from external database or other file formats.  

  • The Data Import Profile Screen is used to develop an import profile, cross-reference external field data to Uncertainty Sidekick Pro fields and to run imports.

  • The Data Import Profile Screen allows the user to view the data prior to importing into Uncertainty Sidekick Pro.

  • The Windows Copy & Paste functions are also supported on all program screens and worksheets.


Correlation of Error Sources

  • All error sources are assumed to be uncorrelated unless otherwise specified by the user.

  • The Correlation Coefficient Worksheet assists the user in establishing correlations between error sources.

  • Correlation coefficients are automatically included in the computation of the total, combined measurement uncertainty.


Analysis of Multivariate Measurements

  • The Parameter Multivariate Worksheet is the primary screen for analyzing uncertainties for multivariate measurements.

  • The equation for computing the parameter value of interest can contain up to 25 root variables or quantities.

  • The parameter value equation can contain nested variables, each of which can be defined by a separate equation.

  • Root variables and associated uncertainties are analyzed via Error Source Uncertainty Worksheets.

  • Sensitivity coefficients for root variables are automatically computed via numerical partial differentiation of the parameter value equation.

  • All equations are entered in the extremely versatile and non-proprietary VB Script format.

  • Multivariate Analyses can be saved separately and imported into other Uncertainty Sidekick Pro analysis files.


Notes Pages for All Analysis Levels

  • There are built-in notes pages for each uncertainty analysis worksheet or screen to store images and text.

  • Notes pages are automatically saved with each analysis and can also be saved externally as rich text format files.


Charts and Plots

  • Parameter bias distribution plots are automatically displayed on the Parameter Bias Uncertainty Worksheets.  

  • Combined error distribution plots are also displayed on the Main Screen.

  • The Pareto Chart Screen displays a bar chart depicting the relative contributions of Type A, Type B, and Type A,B process uncertainties to the total, combined uncertainty.


Comprehensive Analysis Reports

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

  • The Report Options Screen can be used to tailor the contents of each analysis report.

  • Notes, charts and plots can be selected for inclusion on report pages.

  • The Print Preview Screen provides navigation through reports pages prior to printing.

  • Analysis reports can be saved in Rich Text or HTML file formats via the Print Preview Screen.

  • Analysis reports can also be copied and pasted as images in Word, Excel, PowerPoint or other external application. 


Advanced Features

  • The SMPC Analysis is used to obtain the best estimates of both the subject parameter and measuring parameter values using Bayesian methods.

  • The built-in Type B Degrees of Freedom Calculator provides a useful tool for estimating the degrees of freedom for heuristic (i.e., non-statistical) measurement uncertainty estimates.

  • The built-in Measurement Units Database contains over eighty measurement areas and several hundred units in compliance with NIST Special Publication 811.

  • The built-in Instrument Database can be used for storing and retrieving instrument and parameter specifications.

  • External Windows applications can be run from within Uncertainty Sidekick Pro via the Run External Application Screen.

  • Uncertainty Sidekick Pro analysis files are upwardly compatible with UncertaintyAnalyzer for enhanced measurement uncertainty analysis capability.
