FIELD: medical engineering. SUBSTANCE: device has measuring and two indifferent electrodes, current-to-voltage converter, differential amplifier, amplitude detector, standard voltage source, subtracting device, controllable voltage source, and recorder. Novelty in device is introduction of subtracting device, standard voltage source and current-to-voltage converter, as well as manufacture of power supply source in form of controllable voltage source. This allowed formation of nonlinear measuring scale with preset type of nonlinearity. This scale provides for widening of range of recorded electrodermal resistance values when using one measuring range in order to search for acupuncture points and to measure their electrodermal resistance. Device may be used in specialized diagnostic instruments. EFFECT: widening of range of recorded values of electrodermal resistance. 3 dwg
