1   SPCView is sold as a plug-in application for UncertaintyAnalyzer.

2   IntervalMAX is sold as a site license with pricing scaled according to the number of inventory items that are assigned calibration intervals.

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

4   SPCView uses measurement results and uncertainty estimates obtained for various calibration dates to compute the calibration interval for an attribute or parameter of an individual  item or device (i.e., manufacturer/model/serial number).

5  A3 Interval Tester computes an observed reliability based on user specified information about the number of tests/calibrations conducted at the current interval into the number of in-tolerances observed.  An algorithm, based on Method A3 documented in NCSLI RP-1, is used to compare the observed and target/desired reliabilities.  If a significant difference is determined, then a new/revised calibration interval is recommended.

6   IntervalMAX uses reliability modeling, based on Method S2 documented in NCSLI RP-1, to analyze calibration service history data (e.g., observed in-tolerance or out-of-tolerance data) to establish calibration intervals for groups or classes of measuring equipment (i.e., manufacturer/model or similar equipment).  Calibration intervals can be establish for individual items (i.e., manufacturer/model/serial number) that have sufficient service history data.  Method A3 is used when insufficient calibration history are available for Method S2 analysis.

7   IntervalMAX uses efficient algorithms to automatically analyze calibration history data for large, medium or small equipment inventories.  Consequently, optimal calibration intervals are established in the shortest amount of time at minimum expense. 

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

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

10   IntervalMAX imports test/calibration history to an internal  Cumulative History Database.  Various database cleanup functions provide useful tools for maintaining the cumulative history data.

11  Data Import Profile Screen is used to develop an import profile, cross-reference external field data to software fields and to run imports from external database or other file formats.

12  Calibration interval analysis results can be exported to an external database via the External Interval Assignment Screen.

13  AccracyRatio provides plots of risk versus in-tolerance probability, risk versus guardband limits, and baseline risk versus accuracy ratio.

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

15 RiskGuard and A3 Interval Tester analysis results can be copied to the Windows clipboard and pasted into spreadsheet, word processor or other applications.

16 SPCLimits analysis results can be exported into text file.
