The multi-functional integrated circuit tester is a professional instrument designed for engineers and maintenance personnel. Automatically detect NPN and PNP transistors/ automatic identification of the transistor pinout/ Automatic shutdown if there is no operation after 60s. With built-in more than 1300 kinds of various types of chip data models and more than 420 kinds of transistor data models, covering a majority of 24 feet or less common universal devices, which can significantly reduce the workload and improve work efficiency. It can test 74HC series/ 74LS series/ CD4000 series/ HEF400 series/ 4500 series/ operational amplifiers/ interface class chip/ optocoupler transistor automatic identification/ regulator value recognition, and so on.
