Possibilities of precision ohmmeter calibration in the exploitation condition

Increasing of ohmmeter metrological reliability by a resistive code-control measure-imitator under the exploitation conditions is proposed in this article. The correction algorithm of additive errors for both an ohmmeter and a code-control resistive measure-imitator is proposed, which provides invariance to the impact of connecting lines and also remaining commutator parameters. The extreme metrological possibility of remote express ohmmeter checking in the exploitation conditions has been discussed.
