Cheap and Sample Piezoelectric Transducers Testing Instrument

Description :

The HS-520A impedance analyzer can measure and evaluate the parameters and performance of various devices and devices such as piezoelectric ceramic sheets, piezoelectric transducers, and buzzers. Judging by the impedance-phase-frequency curve and the admittance circle, it is clear at a glance.

The impedance-phase-frequency curve and admittance circle of a normal product are shown in the following figure:

But not all of the device's graphics are as shown above. Here are the graphics for several problematic devices:
