Use of Absolute and Relative Specifications

To evaluate the Product coverage of the calibration workload, use the Absolute
specifications. Absolute specifications includes stability, temperature coefficient,
linearity, line and load regulation, and the traceability to external standards. It is
not necessary to add anything to absolute specifications to determine the ratios
between the Product specifications and the tolerance requirements of the
calibration workload.
Relative specifications are provided for enhanced accuracy applications. These
specifications apply when range constants are adjusted (see Range Adjustment).
To calculate the absolute specification, combine the uncertainties of the external
standards and techniques with relative specifications.
Use the specifications to determine the component of instrumental uncertainty for
a particular measurement condition at time of use. When the Product is correctly
calibrated, the specifications can be applied to subsequent uncertainty analyses
as a Type B evaluation of measurement uncertainty. This is estimated as a
normal distribution with a coverage factor of K=2.58. Instrumental measurement
uncertainty is one of many contributors that must be considered in a thorough
uncertainty analysis.

Use of Secondary Performance Specifications

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