This meter is based on the LC resonance principle and incorporates a high-speed microcontroller for precise measurement of small inductance and capacitance. It can measure capacitance from 1pF to 100mF and inductance from 1H 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 microcontroller's internal FLASH memory and are retained after power-off. Capacitance Measurement (C): - Accuracy: 1pF ~ 1F: 1%; 1F ~ 10F: 5% - Resolution: 0.01pF Inductance Measurement (L): - Accuracy: 1H ~ 100mH: 1% - Resolution: 0.001H Large Inductance Measurement (Hi.L): - Accuracy: 100mH ~ 1H: 1%; 1H ~ 100H: 5% - Resolution: 0.001mH Large Capacitance Measurement (Hi.C): - Accuracy: 1F ~ 100mF: 5% - Resolution: 0.01F Test Frequency: - L/C: 500kHz; Hi.L: 500Hz ~ 50kHz Measurement Methods: - Inductance / Capacitance / Large Inductance: LC Resonance - Large Capacitance: Charging and Discharging Display: 1602 LCD Effective Display Digits: 4 Power Supply: Mini USB interface and 5.5mm DC plug Operating Voltage: 5V Color: As shown in photo Material: PCB Package Contents: 1 x High Precision L/C Meter 1 x USB Cable Note: The package includes only the items listed above.
