The accuracy of the Xitron Bio-Impedance Spectrum Analyzer was evaluated over a measurement range of 56 to 626 ohms and using lead resistances from 50 to 600 ohms to simulate electrode impedance(Z). Phase errors without lead resistances were up to 14.9°. Lead impedance could add up to an additional 4° error. Although errors of this size could cause serious problems, it appears that by using low impedance electrodes and software corrections of the data significant improvements can be obtained.
