Work of the circuit The circuit consists of power circuit, temperature controlling circuit, sound warning circuit and pulse heating circuit. (It showed in picture 9-24.) The 220V AC voltage supplies 12V DC working voltage to the whole circuit. The low frequency OSC consists of IC4 and the other parts around. The low frequency pulse signal is outputted from pin 3 of IC4. The signal makes V 1 and EH works with pause. The range of temperature is 37-45℃. If the temperature is higher than 45℃, the high level is exported from pin 10 of IC2. The high level is adjusted and drives HA to make warning sound. When you use the machine, put the medicine on the probe and put it into the anus. Choose the proper temperature to make it work.
