New method of the definition and correction errors procedure in universal ac bridge
The new method for determining the characteristics of systematic errors for the multirange and multiparameter meters of complex impedances is proposed and well-founded. It is based on the separation from the total error of a device of independent components, related to changes in the state of converters of measuring channel in different modes of operation. The possibility is shown to evaluate the real error of devices in any point of the ranges of measured parameters and to correct these errors in the processing of the measurement results using a small number of testing operations and with the limited set of the standards which are widely spreaded.
