FIELD: measurement technology.
SUBSTANCE: device has four current disk electrodes, insulating plate, electrode switch, two variable resistors, voltage registrar, current registrar, two switches, current source. All the electrodes are connected to each other pairwise in turn by means of switch through current registrar, variable resistor and switch. Electrodes are also connected to each other by means of switch through current registrar, current source and switch. Electrode polarization is taken into account to increase the precision of measurements.
EFFECT: improved precision of measurement.
