For many decades, the practice of Acupuncture and Traditional Chinese Medicine (TCM) were considered unscientific until 1951 when Ryodoraku was invented by Dr. Yoshio Nakatani where the measurements of skin conductance at certain acupuncture points can be used for health diagnosis. From then in the following years, many research and clinical trials were carried out to search for the most reliable ways and methods of measurements. In this report, the method and reliability of Ryodoraku measurement will be investigated using the Bio-Pulse TC and Meridian Testing Program. The accuracy of the measuring of average skin conductivity at acupuncture points will be investigated by varying the type, size, and location of the earth electrode, location of the acupuncture points and time of day when measurements are taken. We have proposed an electrical model for measurements taken. The readings from acupuncture points LU9 and LI5 were used to estimate the values of electrical components of the equivalent circuit.
