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. Скорость обновления невысокая, около двух раз в секунду.
-----
the factory current calibration was just fine - there are no deviations in the entire range. shunt of 5 mω. The voltage scale is non-linear - low voltages are underestimated, high voltages are overstated (instead of 5.7, it shows 5.6 V; instead of 24.1, it shows 24.3 V). Measurements were carried out with an external power supply of 5V. The update rate is low, about two times per second.
