    Paket je prišel rahlo poškodovan, vendar merilni inštrument je brezhiben in deluje odlično. Napetost kaže zelo natančno, napetost, pa bo potrebno naravnati na pravi rezultat. Priporočam nakup, zelo kvalitetna izdelava.

    KWS DC200 10A arrived undamaged. The instruction manual shows how to connect with the power supply from the same source what and load. There is a warning there: Don't connetct thin black wire. On the case they show to connect a thin black wire to a thick black wire. So against my own warning. Such connection as on the sticker on the back of the meter in similar designs of voltmeters -ammeters causes their damage. The topic is known and described on the Internet. KEWEISI manufacturer which is correct? I didn't risk damaging it. I connected according to the attached instructions, and not according to the diagram from the housing. It works. Maybe someone was checking it. Write in the comments. Maybe Banggood will find out with the manufacturer where such a discrepancy in the schemes is and give it on the item's page. Another note. The specification gives a supply voltage from 8V to 120V. My copy starts the display only from 14.40V, regardless of the power supply from one or two sources. Below 14.4V, the display (photo) goes out. How do you have in your copies? The measurement error is small (photo), so it's probably not a matter of calibration.

    The multifunction energy meter (50A and 100A versions) comes in a box with three cables and a black metal bar with two inserts (external shunt). It is an essential tool for solar energy. Shows the Voltage, Power, Temperature, Current, Time and Energy. An English well written manual with diagrams is also included. The Red-Black color cable is for current and the Yellow-Red-Black color cable is for the main power. The Black color cable is for temperature measurement. Note that the scratched display was due to a screen protector on the display. After peeling it off, it is fine. It had no problem passing through the full 100W that my power brick delivers and it did not get warm in the process. It works great for my needs.

    Great little (tiny?) meter for a fantastic price ... do _not_ underestimate the size of the current shunt needed (for 50a and 100A - see label)

    Hello good morning!! THE PACKAGE ARRIVES INCOMPLETO I ordered two products of these and I got the package well, but when I uncover them I realized that one piece was missing in one of the bags is the black bar with two inserts and screws that seems to be a resistance and I do need it. Thank you. I'll show you the pictures. In the image on the right the bag is already uncovered but the black bar is missing.

    Not mentioned anywhere is that the temperature probe (that comes with this) can be extended by splicing in extra 2 like wire in order to put it in your remote battery location. I added 15' of wire and it works fine. This is a very useful monitor for my caravan to measure battery usage.

    Nice! I love the color of the font, no boring when I see it. I've been using it for a few months, so far no problems.
