  • The print serigraphy on the board is wrong. It should marks IC tl084. this design should be revised. And publish it properly.

  • Hi, you didn't wrote a list of materials... for example... you didn't explain watts for resistors or precision, even most important... transistors, which serie? it is far different BC547 than BC547-B even farther results than BC547-C. Please, Could you publish it?

  • Hola amigo soy de mexico y compre esta version y tambien la de transistores. Sin embargo si enciende el foco led pero al hacer corto circuito las puntas del tester no enciende el foco de prueb ni la aguja se mueve. Monte todo como lo indicas y use el valor de los mismos componentes de tu placa. Espero ayuda. Si me puedes dar tu numero de whatsapp para comunicarme

  • Hi Adrian, I'm Consiglio Iannuzzi and I bought your PCB on PCBWay. I have mounted all the components but I have a problem, when the switch is turned on, both the led_tester and the led_on turn on and the needle of the multimeter goes towards zero. I can't find what I could have done wrong, can you help me out? Thank you

    CHECK IF YOU HAVE 100KHZ ON PIN 14 OF THE TL084, IF YOU DON'T HAVE, LOOK IF YOUR TL084 IS ORIGINAL AND BRANDED STmicroeletronics

    ok, I'll check and let you know. Thank you

    Hi Adriano, I checked on pin 14 there are 111-112 kHz and the integrated is a TL074CN from Texas Instruments. Please help me solve the problem. Thank you

    Iannuzzi Consiglio 2021-03-15 20:34:27Reply

    I checked the datasheets for both Texas and ST and they are identical

  • Hi, congratulations for the job, I bought the pcb. I would like to know if the potentiometer is 10K and if it is the original mounted on the multimeter. Thank you

    thanks for the purchase, as for the potentiometer you can use 5k or 10k, it's good to mount on the multimeter
