    Bought this to use as a small display for LED power usage. Pros: Comes with shunt (which wasn't necessary for my application, but nice to have) Very bright easy to read display Easy to adjust pots on rear of unit. Cons: Claims to be useable under 10A without shunt. I haven't found that to be to a... Read more

    Pay attention when hooking this up, or you will measure the wrong values. Once hooked up it seems to work fine. With adjustment pots for calibration.

    Pros: cheap, god build quality, easy to read Cons: Not very accurate and the wiring instructions are hard to understand. while this is a very useful piece of hardware, I feel its not as accurate as it should be but its not a big problem. the diagram to use this without a shunt is not as easy o...

    I bought this to replace the terrible ammeter on my Schumacher battery charger, which didn't work. This meter presses into the Schumacher ammeter housing perfectly, meaning all I had to do was to drill two holes for the shut. You will need to take some care in figuring out the wiring diagram the... Read more

    this unit is a good price and does provide basic functionality We setup this to use on a solar suite at 24VDC to monitor the battery load it did work until we had approx 8 amp running and we lost the current feature, this was wired correctly but i think the shunt isn't of the best quality when it...

    Convenient meter for anything powered by a battery, leads could be a bit longer. I'll use it outdoors to keep track of the state of charge of a 12V deep cycle battery and hopefully it can take some moisture.

    The first was not working properly. The voltage was correct, but the currency was always between 40 and 50 amperer even without load. Shunt was ok. I replaced only the LED-device and now it works properly. (For the second order i got 50% discount because i complained) Ich musste den Artikel zwei... Read more

    This is among the items that gave me the most for each dollars spent at DX. The volmeter is fairly precise, <2% difference with a know reliable Fluke multimeter, and just had to do a slight adjustment with one of the two potentiometers at the back to get a reading that is within 0.5% with the i a...
