Impedance studies on test circuits demonstrated that three-point measurements are susceptible to voltage divider distortion/artifacts if the reference electrode impedance approaches the analyzer input impedance. These features can be avoided by using an instrument with a high input impedance or a reference electrode with a low input impedance. A correction procedure is also presented.
