FAQ: Is it possible to measure the capacitance of piezo elements and converters ranging from 2.00 to 4.00 nF? And the electrical insulation?
The TRZ® Analyzer estimate piezo elements and converters capacitance at resonance condition only, it is the C0 parameter from the BVD equivalent circuit shown in the screenshot below. The TRZ® Software is not able to determine the capacitance at arbitrary frequencies. For the typical capacitance test at 1 kHz, we recommend using a LCR multimeter.

The TRZ® Analyzer accessory, PiezoHolder, may be helpful to measure capacitance using a LCR multimeter (see image below) because it avoids scratching the silver electrodes surface.

The TRZ® Analyzer applies only low voltage; therefore, it is not suitable to evaluate electrical insulation. For this purpose, we recommend the use of a HV insulation tester.
