Abstract
A method of and arrangement for measuring impedances, particularly low capacitances, by alternately connecting one or more reference impedances and sensor impedances to a measuring circuit. A programmed memory is used to take into account the individual non-linearities of the impedance sensor(s) and, optionally, to compensate variations of ambient circumstances such as temperature.
