Abstract
A measuring process unit for executing a measuring process of, in correspondence with a plurality of combinations obtained by respectively combining a plurality of connection terminals Tx and a plurality of connection terminals Ty, and in respect of the connection terminals Tx, Ty corresponding to each of the combinations, supplying an AC voltage SA to the connection terminals Ty by means of an AC current source 2 and detecting electric current flowing in the connection terminals Tx by means of an ammeter 3, to thereby acquire currents corresponding to each of the combinations; and a calculating unit for executing a calculating process of, based on the size of the currents detected by the ammeter 3 in the measuring process and on information indicating the currents' phases, calculating capacitance and resistance values corresponding to each of the combinations.
