4.1 Measuring with Constant Voltage or Current (ALC)
4-5 ZM2376
When you measure a high-dielectric type ceramic capacitor that has nonlinear characteristic, it is
recommended to use up to about 10µF at 1kHz and about 100µF at 120Hz. The measured value may
change due to signal distortion, when the voltage drop caused by the output impedance increases.
