FIELD: examination of dynamics of parameters of rocks. SUBSTANCE: device uses method of compensation of voltage from receiving dipole by current of supply diode with the use of one measurement path based on analog-to-digital converter and on time separation of process of measurement of voltage and current. It also uses method of detection and collection of information in digital form with the aid of reversible counter. EFFECT: enhanced accuracy of device. 3 dwg
