Evaluation of measurement uncertainty during verification o electric resistance multivalued used in dc

O.O. Volkov, I.P. Zakharov, A.N. Lapchenko
Annotations languages:

The problems of uncertainty evaluation in the national testing laboratories are discussing. A model of the transmission unit size for resistance testing of multi-valued measures on DC was considered, the procedure for evaluation of measurement uncertainty is described, the uncertainty budget is given. An example of the evaluation of measurement uncertainty in the verification of resistance box with a digital ohmmeter was described.
Keywords: resistance box, verification, calibration, measurement uncertainty, uncertainty budget
