M12864 DIY Transistor Tester Kit Graphics Version for LCR ESR PWM Measurement

M12864 DIY transistor tester kit can automatic detect PNP and NPN bipolar transistor, N, P-channel MOSFET, JFET field effect transistors, diodes, two diodes, thyristors, resistors(0.1 Ohm - 50M Ohm), capacitors, inductors. Automatic detection of current amplification factor (B), pin definitions and emitter junction (Uf) through a high threshold voltage and high current in two seconds, only the large capacitance and high inductance measurements will take a long time.

Main Features:
● One key for measurement operation, auto power off delay. Shutdown current is only 20nA, support for battery operation
● Capacitance measurement range from 25pf to 100mF. 0.09uF capacitance can be detected above the equivalent series resistance (ESR), resolution is 0.01 ohms
● Inductance measurement range from 0.01MH to 20H, otherwise it will be displayed as resistance if the inductor DC resistance is higher than 2100, that will be displayed as the European resistance.
● The square wave signal generator can produce optional built-in stall square wave signal within the range of 1HZ - 2MHZ
● PWM pulse signal generator produce the pulse width modulated signal of 1 - 99 percent
● The frequency meter function can test 1HZ - 25KHZ or higher frequency signal (in this case a slight decrease in accuracy)

    Great product for DIYers
    Found this very useful for testing and figuring out salvaged parts from electronic equipment, to use in other diy projects. I highly recommend this for anyone that does DIY projects to make sure any parts that you maybe using that was pulled from old electronic equipment, if using used parts from old equipment, that usually means it is something that doesn't work anymore so it's good to test all parts that you salvage to ensure all the parts you save are of good quality. It can also help in repair of products instead of scraping it. Assembly was really simple, a great project for a novice starting out to help with learning how to build, and then how to test and identify parts as they learn.
    none for me. but for those complaining about instruction manual a quick google search for a M12864 DIY Transistor Tester manual will turn up several places that you can download a PDF manual

    Хороший и полезный набор
    Хороший набор для обучения или просто приятного проведения времени за любимым занятием и в результате - полезный прибор. В комплекте идет дополнительный конденсатор для настройки. Экранчик простенький, но вполне читабельный. Насчет точности сложно сказать, но, думаю, для любительских измерений вполне подойдет. Набор очень функциональный, умеет не только транзисторы тестировать, если хотите узнать все возможности - скачивайте инструкцию (PDF-файл).
    Отсутствует инструкция, скачать можно в Интернет. Собирал без инструкции, не сразу понял, что джойстик и есть кнопка включения, но потом разобрался.

    Best kit ever !!
    I bought it just to learn soldering and didn't expect the oscilloscope will actually work. It is great fun to solder the kit, and the oscilloscope is very handy in testing electronic signals ( i used it to test rs232 from Raspberry PI RX and TX pins ).
    It is hard to change settings using those 4 buttons, although i have older version of software.

    Good Value
    Great set of features to testing wide range of components
    Easy to assemble, component values marked on board and worked fine when built
    Mine had a resistor missing so had to mark quality down

    Отличный конструктор
    Интересный конструктор, качественно изготовленная плата, качественные электронные компоненты, не требует наладки-доводки.
    хотелось бы наличие корпуса, инструкции по сборке и правилам пользования.

    Good for begginers
    easy to assembly
    good socket
    an additional capacitor for calibration
    good quality PCB
    price could be lower
    no instructions
    9v power supply - could be 9-12V

    Transistor Tester Kit
    Great bargain! The board is clearly marked so it went together well. Worked on first power-up with no problems.
    Would like to have received more extensive documentation on assembly and operation but not a big issue.
