Abstract
A calibration method includes (a) connecting a impedance measuring device to an impedance standard which has at least two excitation terminals for feeding an excitation signal and two measuring terminals for determining a measurement signal, and which has a fixed or adjustable impedance which corresponds to the impedance target; (b) applying a voltage signal to the excitation terminals and measuring the current flowing through the impedance standard due to the voltage signal at the measuring terminals; or supplying a current signal to the excitation terminals and measuring the dropping voltage at the measuring terminals; and (c) calibrating the impedance measuring device against the impedance standard to the impedance target. The geometrical arrangement of terminals of the impedance standard corresponds to the geometrical arrangement of the terminals of the cell of which the impedance is to be measured.
