FIELD: instruments for geophysical investigations. SUBSTANCE: device has measuring unit, two low-frequency oscillators, two commutators-generators, three switches, three transceiver antennas, two master oscillators, two power amplifiers, two receivers, two phase-amplitude detectors, solving unit, relay unit, unit for automatic phase adjustment. EFFECT: increased precision due to automatic detection of conditions when measuring errors are greater than pre-set values. 1 dwg
