This meter, on the base of LC resonance principle, adds precise measurement of high-speed micro-controller so that it can measure small inductance and small capacitance precisely It can measure capacitance(1pF-100mF) and inductance(1uH-100H) It has an advantage over small value testing with precision and minimum resolution Flexible online calibration can always maintain measurement accuracy The calibrated parameters are completely stored in the FLASH inside of micro-controller, wouldn't lost when power-off Adds precise measurement of high-speed micro-controller, suitable for microwave and switching mode power supply transformer. It has advantage over small value testing with precision minimum resolution. Specifications: Color: Green. Material:PCB Capacitance Measurement(C): Accuracy: 1pF~1uF 1%; 1uF~10uF 5%.
