Features Portable Design with Clear Display & Long Battery Life: Designed for production line, and on-site use , the LC1020E features a compact body and a powerful 3.7V, 3000mAh rechargeable lithiums battery. The large 2.8-inch TFT-color screen clearly displays all main and secondary parameters (L/C/R/Z, X/D/Q/θ/ESRs), making it easy to read measurements anywhere. Notice: Actual color may be slightly different from the image due to different display and light effect. Please allow 1-3cm deviation due to manual measurement. Description: Display: 2.8-inch TFT-LCD display Basic Accuracy: 0.3% Display Digits: Main Parameter: 4.5 digits; Secondary Parameter: 4.5 digits Test Frequency: 100Hz, 120Hz, 1KHz, 10KHz, 100KHz Test Level: 0.1V, 0.3V, 0.6V Internal Bias: 0.0V, 0.5V Measurement Parameters: Main Parameters: AUTO/R/C/L/Z; Secondary Parameters: X/D/Q/θ/ESRs Measurement Range: L: 0-100H, C: 0-100mF, R: 0-10MΩ Measurement Speed: Fast (4 times/s), Medium (2 times/s), Slow (1 time/s) Calibration Functions: Open circuit calibration, Short circuit calibration Comparison Function: Used to calculate the relative error between the component measurement value and the nominal value, displayed as a percentage, and provides filtering results. Nominal values and tolerance can be set, with a tolerance range adjustable from 0.1% to 99.9%. Record Function: Checks if the measured component data meets the set nominal value and tolerance, recording the number of successful and failed measurements. Test Terminal Configuration: Three-terminal, Five-terminal Output Impedance: 100Ω Communication Interface: USB-TypeC (Virtual serial port) Other Features: Language settings, Screen brightness, Sound settings, Auto power-off, Calibration settings, System information.
