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 preciselyIt can measure capacitance(1pF-100mF) and inductance(1uH-100H)It has an advantage over small value testing with precision and minimum resolutionFlexible online calibration can always maintain measurement accuracyThe 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.Measurement Mode of Inductance/Capacitance/Large Inductance: LC Resonance.Measurement Mode of Large Capacitance: Charging and Discharging.Display: 1602 LCD.Effective Display Digits: 4.Power Supply: Mini USB Interface and Dia. 5.5 DC Plug.Power Voltage: 5V.color:Photo colorMaterial:PCB Package Contents:1 x High Precision L/C Meter1 x USB Cable Only the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
