This meter, on the base of LC resonance principle, adds precise measurement of high-speed micro-controller so that it can measure small inductance small capacitance precisely It can measure capacitance(1pF-100mF) inductance(1uH-100H) It has an advantage over small value testing with precision 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 Capacitance Measurement(C): Accuracy: 1pF-1uF 1%; 1uF-10uF 5%. Resolution: 0.01pF. Inductance Measurement(L): Accuracy: 1uH-100mH 1%. Resolution: 0.001uH. Large Inductance Measurement(Hi.L): Accuracy: 100mH-1H 1%; 1H-100H 5%. Resolution: 0.001mH. Large Capacitance Measurement(Hi.C): Accuracy: 1uF-100mF 5%. Resolution: 0.01uF. Test Frequency: L/C: 500KHz; Hi.L: 500Hz-50KHz.
