I got these and although they showed the voltage, they showed 0 amps. Reading other reviews I assumed they were bad like the rest. Ordered some from another vendor, plugged them in and had the SAME problem. 0 amps! OK, so it is NOT the meter. Turns out I had the thicker Red/Black wires reversed that measure the load. Changing them around resulted in AMPS APPEARING!!!!!!! AMAZING. hahaha So, if YOUR meters show 0 amps, I suggest re-checking your wiring. Flipping the thicker Red/Black wires around may fix it for you. Your mileage may vary. Some diagrams out there on the internet are probably wrong because I hooked it up according to what found on a google search.There is nothing wrong with the meters.

One of the 2 works well. The documentation could be better, but it's not rocket science. The other one shows the max current, but it won't drop back down as the current drops. In all reality, for the cost, can't complain too much. Serves my purpose.

The meter worked exactly as described. It is best for permanent installation but I was able to use it for a test application. The meter only measures positive current flow, it measures zero for reverse flow.

Cute little meter; I really like it! BUT...Be aware that the minus side of the amp meter is internally connected to the minus side of the power supply and volt meter. This means its APPLICATION is LIMITED to those projects where it is acceptable to monitor the current on the negative side of the load. I consider that undesirable, would rather monitor the supply current, but was able to switch my wiring. However, many applications won't allow that.If the amp meter was isolated, I'd have given it 5 stars.Accuracy seems to be "not bad for a $7 meter," a few tenths of a volt or amp.

Small package, no external parts, self contained, gives both volts and amps for a good price. Not sure why they provided 5 leads, but it works and it gets 5 stars.

After meticuluosly cutting a hole in my 20 amp 12 volt battery charger and mounting the shunt, wiring to spec. refused to work. I set up for isolated 12 volt supply with no success. tried the second setup on a test bed for verification. No luck! Been in the Electronics and Electrical industry since 1976, So with this background I feel secure in saying Nay to this product.

A great volt/ammeter combo! Compact yet very informative. Both lines are easy to read and accurate. Installation isn’t difficult if you follow the detailed wiring diagram(s). The included shunt is robust.

Includes both Voltage and Current trim pots to fine-tune.Current shunt bridge is calibrated with a notch sawed in it. Coated with conformal coating to protect it from shorts.Current bridge must either be used or shorted.Otherwise, it displays a bogus value - 57A at 13.8VDC for mine.

The shunt and meter were checked for accuracy and both tested fine.

The voltage is accurate but the shunt are poor quality and even the adjustment potentiometer is not coarse enough to get the desired value. pay a little more and get better value! DONT buy these!
