Abstract

A kind of electrostatic capacitor inspection apparatus which is used to detect the different capacitor ratio among the inspected capacitors. The inspection range is wide and no need for calibration for both manufacturer and user. It is easy to operate and without the sensitivity bias according to wide range operating environment, static electricity and the water attachment on the inspected objects. The operation is to detect the harmonic frequency alternation of inspected objects by contact or near the inspection electrodes. The changeable frequency generator will have a phase shift with the output and also by control the voltage control oscillation circuit to change the oscillation frequency of the frequency generator so as to detect whether the inspected object is accepted.
