The main approaches of parametric analysis of impedance measuring transducers on the base of SPICE modeling are considered in paper. In the modeling process, the galvanostatic measurement method is used, which is on the base of the determination of the ratio and phase delay between the voltage and the harmonic current with the specified amplitude and frequency. As a result of simulation, the possibility of significant increase of the measurement transformation accuracy is found by means of modifying the input circuits of the impedance measuring transducers.
