Multi-Function Transistor Tester LCR Meter 1.8" TFT Color Screen
Multi-Function Transistor Tester LCR Meter 1.8" TFT Color Screen
Multi-Function Transistor Tester & LCR Meter with 1.8" TFT Color Screen
Whether you're a hobbyist, electronics technician, or engineer, this all-in-one Multi-Function Transistor Tester and LCR Meter is the ultimate bench companion. With a vivid 1.8" TFT color display and one-click operation, it automatically identifies and tests a wide range of electronic components — from diodes and MOSFETs to capacitors, inductors, and even IR remote control signals. Made in Mainland China.
Key Features
- Automatic Component Detection: Instantly identifies NPN & PNP transistors, N-channel & P-channel MOSFETs, IGBT diodes (including double diodes), thyristors, resistors, capacitors, and inductors — no manual configuration needed.
- 1.8" TFT Color Display: Graphically displays component parameters, pin layouts, and measurement results in a clear, easy-to-read color format.

Wide Measurement Ranges:
- Capacitance: 25pF – 100mF (with ESR measurement)
- Inductance: 0.01mH – 100mH
- Resistance: 0.01Ω – 50MΩ (resolution: 0.1Ω)
- Voltage Detection: 0.1V – 4.5V
- IR Remote Control Decoding: Detects and decodes NEC-format infrared remote control signals — great for troubleshooting IR devices.
- MOSFET Analysis: Distinguishes depletion-type from enhancement-type MOSFETs, and measures gate threshold voltage and gate capacitance.
- Advanced Capacitor Testing: For capacitors above 10µF, displays VOSS and ESR values for deeper analysis.
- Fast Test Speed: Most components are identified in approximately 2 seconds (large capacitors may require additional time).
- Built-in Rechargeable Battery: Equipped with a 300mAh 4.2V lithium battery for portable, cord-free use.
- One-Click Calibration: Includes a calibration needle for precise small-resistance measurements. One-click calibration makes setup effortless.
- Auto Power-Off: Automatic shutdown mode draws less than 20nA, preserving battery life when the device is not in use.
- Pin Layout Display: Automatically tests and graphically displays the pin layout of detected components on-screen.

Frequently Asked Questions
Q: What types of components can this transistor tester identify?
A: This multi-function tester automatically detects and identifies NPN and PNP bipolar transistors (BJT), N-channel and P-channel MOSFETs, IGBT diodes (including double diodes), thyristors, resistors, capacitors, inductors, and batteries. It also decodes NEC-format infrared remote control signals.
Q: Does the transistor tester come with a battery included?
A: Yes — the unit features a built-in 300mAh 4.2V rechargeable lithium battery. No separate battery purchase is required. The auto power-off feature (drawing less than 20nA in off mode) helps extend battery life significantly.
Q: How do I calibrate the LCR meter for accurate small-resistance readings?
A: The tester includes a calibration needle and supports one-click calibration. Simply use the included needle to short the test leads and press the button to calibrate. This ensures highly accurate measurements, especially for low-resistance components.
Q: Can this tester distinguish between depletion-type and enhancement-type MOSFETs?
A: Yes. The tester automatically distinguishes between depletion-type and enhancement-type MOSFETs and also measures gate threshold voltage and gate capacitance, making it ideal for in-depth MOSFET characterization.
