Fluke 5720A service manual Using Secondary Performance Specifications

Introduction and Specifications 1

Specifications

You do not need to add anything to absolute uncertainty to determine the ratios between the calibrator’s uncertainties and the uncertainties of your calibration workload.

Relative uncertainty specifications are provided for enhanced accuracy applications. These specifications apply when range constants are adjusted (see “Range Calibration”). To calculate absolute uncertainty, you must combine the uncertainties of your external standards and techniques with relative uncertainty.

1-27. Using Secondary Performance Specifications

Secondary performance specifications and operating characteristics are included in uncertainty specifications. They are provided for special calibration requirements such as stability or linearity testing.
