Digital measurement metrology. Part 2

The article analyses the basic concepts of the metrology of the measuring systems and its modification - the automatic power consumption accounting and monitoring system. The article shows the drawbacks of the historical methods of the metrological certification of the digital measuring systems and the automatic power consumption accounting and monitoring system. It is suggested that in the said modern systems, only their input part - the primary digital measuring devices or the measuring channels with the digital output - should be metrologically certified as the measuring devices, and the other system devices should be considered as the secondary nonmeasuring devices which require the digital certification, but not the metrological one. Such approach allows the considerable reduction of costs for the metrological support of the measuring systems and theautomatic power consumption accounting and monitoring system.
