A four-terminal pair fully digital impedance ratio bridge is described. Its principle of operation including balancing procedure and calculation of unknown impedance value is presented. An initial 1:1 ratio check of the bridge has been performed. Systematic errors of the bridge design and actions to deal with these errors are shown.
