LCRT7 transistor tester is a multifunction instrument that tests TFT, diodes, and triodes, and measures capacitance, LCR, and ESR. It accurately identifies transistor types, clearly distinguishing NPN and PNP transistors for reliable results. It supports MOSFETs and IR components, making it a versatile tool for testing a wide range of electronic devices. It provides precise measurements for various electronic parameters with advanced functions to support efficient circuit analysis. As a combined tester and multimeter, it simplifies checking components, saving time in electronics maintenance and repair. Use scenarios: - In a repair workflow, quickly verify transistor types and MOSFETs before replacement to reduce guesswork. - Troubleshoot a power supply by testing diodes, capacitors, LCR and ESR to locate failed parts. - During development or repair, verify TFTs, IR components, and general diodes/triodes to confirm circuit behavior.
