Specifications: It works based on the L/C resonance principle. This L/C meter has high speed microcontroller's precision computation. The measuring range is below 1uH and1pF. It especially qualify in microwave manufacture and measuring switching power supply transformer, filter inductance. Item Name: Inductance Meter Material: PCB LC100-A has four measurement ranges: 1. C Level: Inductance Measurement (0.01PF-10uf) 2. L Level: Inductance Measurement (0.001uh-100mh) 3. Hi.L Level: Inductance Measurement (0.001 mh-100h) 4. Hi.C Level: Inductance Measurement (1UF-100MF) Test Evaluation Rate: L Level, C Level: 500kHz Hi.L Level: 500Hz-50KHz Inductance, Capacitance and Large Inductance Measurement Method: LC Resonance Large Capacitance Measurement Method: Charge and Discharge Display Mode: 1602 LCD Screen Effective Display Digits: 4 Power Supply Interface: Mini USB and 5.5DC Socket Power Supply Voltage: 5V Features: High Precision, Digital, with USB Interface Size: 80mm x 50mm x 30mm/3.15" x 1.97" x 1.18" (Approx.) Notes: Due to the light and screen setting difference, the items color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
