Features:  Four measuring ranges position: C ranges, L ranges, Hi.L ranges, Hi.C ranges, the measuring ranges is 1pF~100mF 1uH~100H.  With the frequency display function, while measuring the element, you can view the current frequency.  The instrument has a flexible online calibration function, which can maintain measurement accuracy at any time. The calibration parameters are completely stored in  FLASH of the microcontroller, and will not be lost even if the power is off. It is more accurate and convenient than others.  Comes with the reset calibration modes, under capacitance mode is open circuit calibration and shows short circuit calibration under inductance mode.  Wide applications: Suitable for scientific research and technical engineering, factory electronic instrument testing, electronic instrument maintenance, school experiment, etc.  Specifications:  Material: ABS  Capacitance accuracy:  1pF~1uF: 1%  1uF~10uF: 5%  Measurement resolution of capacitance (C Ranges): 0.01pF  Inductance accuracy:  1uH~100mH: 1%  Measurement resolution of inductance: (L Ranges): 0.001uH  Large inductance accuracy:  100mH~1H: 1%  1H~100H: 5%  Measurement resolution of large inductance（Hi.L Range）: 0.001mH  Large capacitance accuracy:  1uF~100mF: 5%  Measurement resolution of large capacitance（Hi.C Range) : 0.01uF  Test frequency:  L Ranges, C Ranges: 500kHz  Hi.L Ranges: 500Hz ~50KHz  Measurement method of capacitance, Inductance and Large Inductance: LC Resonance  Measurement method of large capacitance: recharge-discharge  Effective display digits: 4 digits  Supplys voltage: 5V  Power: 4 * AA battery (NOT INCLUDED)  Package size: 160 * 130 * 50mm / 6.3 * 5.1 * 2.0in  Package weight: 300g / 10.6ounce  Packing list:  1 * Capacitance Inductance Meter  1 * Test Clip  1 * User Manual  1 * USB Cable
