Compact, high-quality electronic component tester with a rechargeable 3.7V lithium battery and USB charging. Automatically identifies component pinouts and displays results on a clear graphical screen for easy reading. Tests resistors (0.01Ω–50MΩ), capacitors (25pF–100mF), inductors (0.01mH–20H), diodes, transistors, MOSFETs, thyristors, Darlington transistors, IGBTs (accuracy may vary on high-power devices), and batteries (0.1–4.5V). Also decodes NEC-format infrared remote signals. Simply place the component in the test area and press START for automatic measurement. Note: Always discharge capacitors before testing and never use the tester on live circuits, as this may damage the tester or circuit board.
