This meter is based on the LC resonance principle and features a high-speed micro-controller for precise measurement of small inductance and capacitance. It can measure capacitance from 1pF to 100mF and inductance from 1uH to 100H. It offers high precision and fine resolution for small value measurements. Flexible online calibration helps maintain measurement accuracy. Calibrated parameters are stored in the micro-controller's internal FLASH memory and are retained when power is off. Designed for use with microwave and switching mode power supply transformers.
