In the figure are the multi-function electric point detector and therapeutic apparatus circuit. The point detector and therapeutic apparatus consists of the point detecting circuit, timer, pulse generator and power amplifier output, etc. The point detecting circuit, which consists of BG1,BG2,R1～R4,W1,C1,BG3,B1 and so on, is factually an audio oscillator. If we insert two probes of two poles in the hole of CK1, then because the resistance of the point is low, or due to the low resistance that is caused by the ear illness, the frequency of the oscillator turns high; the longer the distance between the point and the probe is, the lower the frequency will be, so the point detection can be fulfilled.
