FIELD: measurement equipment.
SUBSTANCE: in process of operation they periodically determine values of a measured parameter and the controlled parameter of the measurement facility in process of operation, produced values of the controlled parameter are compared with the received reference value, each produced value of the measured value is memorised, as well as the appropriate current value of the controlled parameter, differences are calculated between the last received value of the measured value and its values received previously, for values of the measured value, the difference of which exceeds the tripled permissible error of measurements, they compare to each other their appropriate current values of the controlled parameter, and following the comparison results, they decide on metrological operability of the intelligent measurement facility.
EFFECT: provision of the possibility to implement periodical control of metrological operability of an intelligent measurement facility in process of its operation.
