FNIRSI® LC1020E High Precision Handheld Digital Bridge LCR ESR Tester

FNIRSI® LC1020E High Precision Handheld Digital Bridge LCR ESR Tester

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 Resolution
    Achieves up to ±0.05% basic accuracy, offering 10× improved precision for professional-grade measurements.

  • Wide Parameter Support
    Measures 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 Identification
    Automatically recognizes R/L/C components and switches modes instantly — ensuring fast and efficient testing with minimal manual input.

  • Multi-Frequency & Test Voltage Selection
    Supports 5 test frequencies: 100Hz, 120Hz, 1kHz, 10kHz, 100kHz
    Offers 3 RMS test levels: 0.1V, 0.3V, 0.6V — providing precise control across different testing scenarios.

  • Sorting & Comparison Function
    Set 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 Voltage
    Built-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 Screen
    Clearly shows both main and secondary parameters in real time — easy to read anytime, anywhere.

  • Open & Short Calibration
    Calibrate test fixtures and eliminate system errors for accurate and repeatable results.

  • Data Hold & Logging Mode
    Short press to hold reading, long press to enter logging mode — with categorized statistics on pass/fail results for improved test efficiency.

  • Compact & Rechargeable Design
    Lightweight, portable body powered by a 3.7V 3000mAh lithium battery, perfect for lab, production line, and field use.
