- Design: The Transistor Tester Kit features a color display for multiparameter measurements on a range of devices. It is a purpose-built, multifunctional electronic test instrument. - Easy to use: The tester offers a simple plug-and-play process; components can be inserted and removed easily, and their parameters are identified quickly to improve testing efficiency. - Wide applications: It can be used to detect and analyze diodes, transistors, capacitors, resistors, and other common components. - Function and safety: The tester includes intelligent discharge protection. Uncharged capacitors discharge automatically upon insertion to prevent damage. - Use scenario 1: On a service bench, quickly diagnose a faulty power supply by testing diodes and transistors. - Use scenario 2: In DIY projects, identify unknown components during prototyping to ensure correct substitutions. - Use scenario 3: Inspect boards during repair to verify capacitor and resistor parameters before reassembly.
