The impedance analyzer is an electronic test instrument that can measure the change of complex resistance with the test frequency. Impedance is a very important parameter for characterizing electronic components, electronic circuits and component materials. The impedance analyzer can accurately measure in the impedance range and wide frequency range. It uses the object to have different conductive effects. When the low-level current is fixed on the surface of the object, the various devices and equipment parameters of the object are calculated through the impedance And the performance is an important industrial testing instrument. The design of the impedance analyzer adopts AC220V low-voltage power supply and current impedance impedance method for impedance test. It can automatically apply current to the AB, BC and CA high-voltage windings of the transformer, synchronously collect data, and automatically calculate the percentage of impedance error. The test results are very intuitive. The resistance analyzer is designed with stable structure, good performance, accurate, fast and reliable measurement data, easy to use, combination of indicators and diagrams, accurate parameters, all-round, high-level protection design, and perfect overvoltage and overcurrent Protection, sturdy and durable, safe and reliable, very convenient to use. The appearance design is neat and intuitive, the surface process is exquisite, and the details are perfect. The four edges and corners are rounded in curve design, soft in texture, and visually give people a simple, friendly and beautiful feeling. It also has a heat dissipation design, a round hole design, and good heat dissipation performance. Plastic handle design, comfortable grip, easy to move. Friendly man-machine interface, high-definition display, reasonable key layout, easy operation, clear and intuitive interface. It is suitable for measuring the impedance characteristics of various ultrasonic devices such as piezoelectric ceramics, ultrasonic cleaning machines, ultrasonic plastic welding machines, ultrasonic pulverizers, and has a wide range of applications.
