Abstract
A device for measuring and indicating changes in the resistance of a living body including an analog portion, a digital portion and a source of power for supplying stable power to the analog and digital portions. The analog portion includes a bridge network which includes a potentiometer for setting a reference level for the device. The digital portion includes a potentiometer which turns together with the potentiometer provided in the analog portion and digital processing circuitry and digital displays for determining and displaying a count indicative of the position of the potentiometer and the total amount of rotation of said potentiometer. In addition, a computer could be interfaced with the device to record or play back the changes in the resistance of the living body.
