      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.

        Q: Does this meter sense DC current on its own, or does it need an external shunt? THANK YOU!!!

        Q: The wiring diagrams depicted are ( plus) common. Is there any (-) common wiring configuration? To place meter voltage / current on a twin voltage supply (one meter for each output voltage / current) I'd prefer a (-) common configuration so the (-) negative outputs are common.
        A:
        Oh, I did n’t try to connect the dual power supply. I think this product may not be connected to the dual power supply.

        A:
        There are diagrams in the product description. Thin red and black supply operating power to the meter. Thick red and black connect to the circuit being measured for voltage. The third thin wire (white or yellow) connects to the measured circuit, to read current.

        Q: is there a connection between the power supply and the voltage to be measured ? (e.g. the minus) thanks
        A:
        ThePSU that powers the unit can be independent from the power source you are measuring if that's what you mean! But generally I think components like this are meant to be part of a designed system that utilises the same PSU. It depends on your application!

        Q: I don't see the electrical drawing anywhere under the product description. Exactly where is added to the Internet wiring diagram? What link is it currently available on? - I don't know the difference between them and them description. Does WHERE is the wiring chart on the Internet? What link is available?
        A:
        Click the link that says “See all description”. The connection diagrams showing how to use this tester to monitor a circuit are there. However, perhaps what you are really asking for, is a circuit diagram of the tester itself? I don’t think the manufacturer is going to give you that detail.
