Annotations languages:

A model of the transmission unit size for resistance testing of digital ohmmeters on DC was considered, describes the pro- cedure for evaluation of measurement uncertainty, given the uncertainty budget. The difference between verification and calibration problems of digital ohmmeters are discussing. An example of the evaluation of measurement uncertainty in the verification (calibration) of Resistomat with a standard resistance coil was described.
