1. Foolproof One-Touch Operation: No need to distinguish component pins or set parameters manually. Just the component into any of the 3 pins randomly, press the test button, and the tester will automatically identify the component type, pin configuration, and display results graphically. It’s user-friendly for both professionals and beginners, saving time and effort. 2. Multi-Component Compatibility: Automatically detects a wide range of electronic components, including PNP/NPN bipolar transistors, N-channel/P-channel MOSFETs, JFETs, diodes, dual diodes, thyristors, resistors, capacitors, and inductors. It also identifies pin assignments for each component accurately, meeting diverse testing needs. 3. High Precision & Wide Measurement Range: Features high-resolution measurement with resistance range 0.5Ω–50MΩ (0.1Ω resolution), inductance 0.01mH–20H, and capacitance 25pF–100,000µF (1pF resolution). It also measures ESR of capacitors >2µF (0.01Ω resolution) and detects capacitor performance via VLoss and ESR values. 4. Practical Functions & Energy Saving: Equipped with one-touch measurement and automatic power-off delay function, with extremely low shutdown current (only 20nA), suitable for DC 9V 6F22 battery power supply (battery not included). Each test takes about 2 seconds, efficient and energy-saving. 5. Clear LCD Display & Additional Features: Displays test results, parameters (such as hFE, Uf, threshold voltage) and component pin configuration graphically on the LCD screen for easy reading. It can detect internal protection diodes of transistors/MOSFETs, test two resistors simultaneously, and light up LEDs during detection., Manufacturer: DIGNIFE
