While many metrologists possess the necessary mathematical skills and training to perform uncertainty analysis, almost all find themselves overwhelmed by the enormity of the task, given requirements to mass produce calculations, line-by-line, test point-by-test point, across literally hundreds or even thousands of calibrations typically performed in a year's time. MudCats provides the tools for automating this task and for managing the details of the calculations so that consistent and reliable results can be achieved every time.

MudCats permits the user to develop a detailed error budget for each line item in a calibration datasheet, to save the error budget as a template for future calibrations, or to simply let the automatic features of MudCats perform the analysis when system information is available and adequate to define the uncertainty. Access to these features is controlled so that only authorized persons can make decisions about the content of error budgets, and all changes are recorded for purposes of document control. A record is retained of the settings in effect at each calibration.

When a calibration datasheet is created or opened from those available in the system library, and after calibration standards have been assigned, the Measurement Uncertainty Wizard provides a grid for developing a detailed error budget. Starting with the specifications for the unit under test embedded in the datasheet, including its resolution, and by finding the accuracy specifications for the standards used in the exclusive SpecTrack database, the Wizard immediately has access to key pieces of information needed to determine measurement uncertainty. If other sources of errors are present and have been previously defined, these too will automatically appear in the grid. Or, authorized users may add or delete error components as necessary.
