FNIRSI® LC1020E High-Precision Handheld LCR Meter is a portable and intelligent tool for testing electronic components, ideal for engineers, technicians, and hobbyists. It supports L/Q, C/D, and R/D measurements with series/parallel models, and features a 2.8-inch TFT color display. Features: High-Precision Measurement with 4.5-Digit ResolutionAchieves up to ±0.05% basic accuracy, offering 10× improved precision for professional-grade measurements. Wide Parameter SupportMeasures L/C/R/Z values with automatic mode switching, and displays X/D/Q/θ/ESR as secondary parameters for comprehensive component analysis. Smart Auto Component IdentificationAutomatically recognizes R/L/C components and switches modes instantly — ensuring fast and efficient testing with minimal manual input. Multi-Frequency & Test Voltage SelectionSupports 5 test frequencies: 100Hz, 120Hz, 1kHz, 10kHz, 100kHzOffers 3 RMS test levels: 0.1V, 0.3V, 0.6V — providing precise control across different testing scenarios. Sorting & Comparison FunctionSet nominal values and tolerances (0.1%–99.9%) for automatic pass/fail judgment, with audio-visual prompts for fast batch testing and quality control. Internal Bias VoltageBuilt-in bias voltage stabilizes readings and enhances measurement accuracy for sensitive components. Dual Test Ports: 3-Terminal & 5-Terminal (4-Wire Kelvin)Ensures both ease of use and maximum accuracy by minimizing lead resistance error. Dual-Parameter Display on 2.8" TFT ScreenClearly shows both main and secondary parameters in real time — easy to read anytime, anywhere. Open & Short CalibrationCalibrate test fixtures and eliminate system errors for accurate and repeatable results. Data Hold & Logging ModeShort press to hold reading, long press to enter logging mode — with categorized statistics on pass/fail results for improved test efficiency. Compact & Rechargeable DesignLightweight, portable body powered by a 3.7V 3000mAh lithium battery, perfect for lab, production line, and field use.
