Patent Abstract
The method involves impressing an alternate current on a specimen (16), where an impression with alternate current is carried out at two locations with a device for the impression. The resulting electromagnetic signal is measured with another unit. Another impression of alternate current with amplitudes and phases that are alternate to the previous measurement is carried out at the same two locations of the specimen and the resulting signal is measured again. An independent claim is included for a device for measurement of the impedance of a specimen.
