A device for measuring the decrement of the electric cutaneous resistance contains the measuring electrode with small contact area, the reference electrode with large contact area connected to the shared grounded bus, the automatic switch with its input connected to the output of multivibrator, two bandpass amplifies connected with the inputs of the multiplier unit with the output of multiplier connected to the low-pass filter. The device also contains the second measuring electrode with small contact area, the second automatic switch and the connected in series the amplifier of video pulses, log-converter, the smoothing resistor, two accumulating capacitors, and the differential voltmeter. |
