FIELD: measurement technology. SUBSTANCE: device has two amplifiers, measuring and two passive electrodes, three electronic switches, comparator, two storage units, two multivibrators, commutator, two calibrated resistors, amplitude detector, controllable voltage divider, standard voltage source, and recorder. Introduction into device of commutator, two calibrated resistors, amplitude detector, controllable voltage divider, second multivibrator, and standard voltage source enabled measurement of electrodermal resistance on measuring alternating current at minium amplitude of the latter, which made it possible to enhance measurement accuracy due to elimination of errors caused by effect of polarization potentials and by variation of recorded parameters because of measuring current action. EFFECT: enhanced measurement accuracy. 2 dwg
