摘要

The method of increasing metrological reliability of measurement channels included in the peripheral modules of distributed automated control systems of technological processes is described. The proposed technical solutions provide high accuracy of determination and subsequent correction of the additive, nonlinear and multiplicative (relative to the voltage source of the calibration) error components included in the measurement channel. In this case, the non-excluded components of the error are much less than the errors of the elements used to determine the errors of analog-to-digital converters. Procedures for determining errors are carried out in the process of the system operation without dismantling its components and outages. Thus, the method provides high metrological reliability and reliability of the received source code of analog-to-digital converters.
