The Development of the Metrological Model for Frequency Analyser of Direct Action Impedance

Yu.V. Khoma, R.M. Ivakh, I.D. Pytel


The structure and characteristics of measuring channel impedance measurement tools based on active measuring transducers are analysed. To assess the accuracy of measuring channel frequency impedance analyser a metrology measuring channel model is developed. The model concerns the main source of errors and displays the structure of measuring change, and also illustrates the major sources of an error and place and displays their location with their relationship. Based on the analysis, the most significant sources of error are defined, and also the methods to reduce their impact proposed.
