The structure of an automated system for measuring the complex resistance of the human body and the phase difference is proposed. It is used in the rheographic method for diagnosing human cardiovascular system diseases using a multilevel microcontroller structure. The metrological analysis of the automated system made it possible to achieve an increase in the measurement accuracy both by reducing the methodological and instrumental components of measurement errors. The relative basic measurement error does not exceed ± 0.5%.
