![]() ![]() ata models and 420 transistor data models.Cover a majority of 24 feet or less common universal devices.Automatically detects NPN and PNP transistors, FET, SCR, automatic identification of the transistor pinout.Automatic shutdown if there is no operation after 60s.Can significantly reduce the workload and improve work efficiency. If the site has helped you and you also want to help others, please Upload a manual, circuit diagram or eeprom that is not yet available on the site. Here the transistor tester circuit using 555 timer works as a Astable Multivibrator circuit and produce square pulse output depends on the timing Resistor and timing Capacitor value.1 x Phillips screwdriver 1 x Small or needle nose plyers 1 x 9 volt battery not supplied in the kit. odels 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.Features:Multi-functional IC tester, transistor tester with LCD digital display.It can test 74HC series, 74LS series, CD4000 series, HEF400 series, 4500 series, operational amplifiers, etc.Different test modes can be selected: 3.3V/5.0V/AUTO modes.Built-in more than 1300 typesf chip Step 1: Tools & Parts Gather what you need first.AVR Transistor Tester 128圆4. However I will put it here, along with manual. It should be mentioned that PCB is very well done and markings are very clear so we didnt need schematic. It is built-in more than 1300 kinds of various types of chipata Step 1: Unpacking At this step I put some pictures to have an overview about what is this kit. Power Supply: No battery included, Includes 12 Volt DC adapter with the kit. ![]() 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.
