Work of the circuit The circuit consists of probing poles, transistor V1-V3, resistor R1-R4, potentiometer RP, capacitor C, amplifier BL, diode VD, switch GB and battery GB. (It is showed in picture 9-38.) Turn on power switch S. let the tester put the poles in their hands. Use the poles to test the relevant parts and body. When the acupoint is not tested, BL makes no sounds. When the acupoint is tested BL screams. Change the value of RP to change the sensitivity of the circuit.
