  A method of electronic conductivity measurement is presented. It combines two
well known methods of electrochemistry: cyclic voltammetry and
chronoamperometry. This DC technique uses the Hebb/Wagner approach to block
ionic conduction when steady state conditions are reached and allows electronic
conduction of solid electrolytes to be determined. In order to get short
diffusion times, a micro contact is used as an ion blocking electrode. However,
as the electronic conduction in electrolytes is and should be very low, the
current is also very low, typically some tens of nanoamps. Thus, the heating
system inevitably generates noise problems that are solved using a median
filter. Our system allows the determination of the conductivities without any
preliminary smoothing or fitting of the curves. Some results with oxygen ion
conductors are also give
