It supports L/Q, C/D, and R/D measurements with series/parallel models, and features a 2.8-inch TFT color display. With preset thresholds and audio-visual alerts, it enables fast pass/fail judgments, improving batch testing and quality control. Supporting up to 100 kHz test frequency, it handles high-frequency analysis of inductors, capacitors, and resistors. Its compact, battery-powered design allows precise, cable-free measurements anytime, anywhere. 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.
