Background. The relevance of the topic is due to the existence of measuring spheres, in which metrological service is difficult or impossible. The aim of the work is to develop the operation rules for the Measurement Instruments, having a metrological autotracking system, based on the exemplary signals method.
Results. An approach to the organization of measuring instruments depending on the ratio of the metrological characteristics drift velocity and the sampling frequency is developed. Examples of nonparametric rank criterion application are given to demonstrate the its capabilities limitations. Rules have been developed to prevent the occurrence of second kind errors. The metrological auto-tracking system tasks are defined. A measuring instruments graph of states with metrological self-control is developed.
Conclusion. There could be a statistically valid correction of the conversion characteristic in a small sample. The system of metrological automatic tracking it is advisable to develop with the use of automata theory.
