(a) Constant voltage circuit. (b) A constant current circuit connected to a power source that generates a higher voltage than a constant voltage circuit. (c) A first diode interposed between the constant current circuit and the potentiometer, the anode of which faces the constant current circuit and the cathode of which faces the potentiometer. (d) A second diode that is interposed between the constant current circuit and the constant voltage circuit, and has an anode facing the constant current circuit and a cathode facing the constant voltage circuit. (E) Analog-to-digital converter equipped with a signal voltage input terminal and a reference voltage input terminal. The signal voltage input terminal is connected to a movable contact of the potentiometer and receives a signal voltage from the movable contact. The reference voltage input terminal is connected to a connection point between the second diode and the constant voltage circuit, and receives a reference voltage from the constant voltage circuit. In analog-to-digital converters,
Converts the signal voltage into digital data based on the reference voltage.
