    Хороший прибор, рекомендую. Есть корректировка показаний. На точность не претендует, а как индикатор для самолета, пойдет. В посылке 3 штуки красного цвета. Подключение по 2-м проводам.

    Producto excelente para controlar las salidas de fuentes autoconstruidas. Hay que tener en cuenta que solo funcionan a partir de 2,5 a 3,0 voltios ya que es la tension de alimentacion del propio circuito y no pueden medir menos. Para menos voltaje es necesario uno de tres cables con toma de alimentación. La soldadura de los cables parece un poco endeble pero se soluciona con una gota de adhesivo termofusionable.

    There's NO idea of to build of something like this of your own. Just bye it here, (no adv.. here.) You wouldn't build your soldering iron- / bicykly/ / carprinter- from scrap. Take the wisdom I've learned my own wisdom. Just buy it here, (no adv. here), it just is. Gonna add this to my on photo's existing powersupply

    Всё работает, претензий нет. Хорошее качество сборки. На калибровку не проверял пока, но в любом случае на плате есть потенциометр для калибровки показаний. Очень компактный, для своих проектов просто замечательно! Рекомендую.

    Good product fot this price. Brightness depends on the voltage. In third photo you can see low brightness at minimum voltage (2,39V): under this value, display is OFF (first photo). At maximum voltage, precision is low (see second photo): error is about 0.5V

    I'm using these voltmeters to monitor the output on a PC power supply which serves as my bench power source. When they arrived they read a few hundreths of a volt low but I was able to easily calibrate them with the adjustment pot on the back. Could be a little brighter but for the money they're pretty amazing really....buck a piece and you can stick them anywhere.

    Ordered 3 pieces, works very well, already incorporated into two of my projects. Nice clearly readable numbers, possibility to calibrate if it is a bit off.

    Have bought in the past. You no longer have to cut away zero resistor, just add 3rd wire:-) Great BG Deals here folks!
