Impedance analyzer can measure and evaluate the matching with the circuit. For piezoelectric ceramic chips, the quality of the device can be directly judged from the admittance circle diagram and logarithmic coordinates. If there are layers or cracks inside the ceramic chip, the logarithmic curve will have multiple peaks, and multiple parasitic small circles will appear on the admittance circle diagram. For the design, processing, and assembly of the amplitude converter, whether it is reasonable or defective, It can be clearly seen directly on the guide circle diagram. For the production and processing of ultrasonic welding machines, the results of the admittance circle are used to analyze the state of the welding machine. Through parameter and graphic analysis, problems with the welding machine are identified. For the production and processing of ultrasonic cleaning machines, the selection of vibrators requires their vibration performance to be as consistent as possible (bandwidth, quality factor, resonance frequency, dynamic impedance). On the admittance circle diagram, There should be no parasitic circles as much as possible or near the resonance point. Impedance characteristics analysis and measurement can be conducted on the manufacturing of the transducer, incoming material inspection, bonded transducer, and cleaning machine. For the measurement of the entire cleaning machine, the resonance frequency and static capacitance of the machine can be calibrated to match the power supply. The characteristics of its new resonance point, impedance after water injection, capacitance, and vibration mode of the entire machine can be analyzed
