    Works as expected. Starts working at a supply voltage of 3.3V. It then draws 6.4 mA. At 5V supply the consumption is 10 mA and it remains at 10 mA up to at least 30V. Accuracy is not the best. For 3.3V with 3.3V supply voltage the error was 12%. For voltage above 4V the accuracy is about 1%, it is however trimmable by some trimpots that are accessible.

    заводская калибровка тока оказалась просто прекрасна - отклонений нет во всем диапазоне. шунт 5 мОм. По напряжению шкала нелинейная - низкие напряжения занижает, высокие завышает (вместо 5,7 показывает 5,6В ; вместо 24.1 показывает 24.3 В ). Замеры проводились при внешнем питании 5В.

    Fast shipping, on time delivery and in good packaging, I ordered 3 pieces of the product to combine with some of my power supply projects. All seem to abe OK. I have tested the product and itlling is working very good as described in selling page. Give some attention to connection diagram appearing in selling page that is very helpful. Vey satisfied ! Γρήγορη αποστολή και παράδοση στον αναμενόμενο χρόνο. Παρήγγειλα 3 τεμάχια που

    Well made panel, once calibrated (trimmer on the board) it does its job. there are no instructions but it is easy to understand how to connect it, it comes complete with cables.

    This voltage and current meter is very nice for the price. You get one decimal place so it should be good for getting a close enough reading on your power consumption and it is very easy to read. It only takes a minute to set up and if you want to adjust the readings there are two potentiometers on the back of the device just for that. Overall it's a good meter for a low price.

    Arrivato nei tempi lo strumento corrisponde alle specifiche installato su alimentatore fa il suo lavoro, ovviamente non ci sono pretese particolari visto il prezzo ,comunque buono.
