Easy to hook-up, and is very accurate, it agrees with published specifications dead-on.

WendyWendy:
The voltmeter worked fine, but the ammeter did not work as expected. Another post mentioned this about the product and I confirmed that until I was drawing ~200mA, the current meter read 0.00A at all times even after I attempted to calibrate it using the I-adj potentiometer. I purchased these units for low power application monitoring so they will be returned. Oddly enough however, as I was adjusting the pot, using a small metal jeweler's screwdriver (touching nothing by the potentiometer), as soon as I touched the pot, a current reading would appear. As soon as I removed the screwdriver the reading went back to 0.00A. Very odd behavior indeed. You'll note also that the version of PCB of the units I received look COMPLETELY different than the photos of the units being advertised on Amazon. Perhaps I received an obsolete version of the panel meter or it has to be wired differently than the diagram posted with this item on Amazon, but I could not get it to work despite my 30 years of engineering experience.
I also purchased a DROK high accuracy panel voltmeter/ammeter in the same order and it is working as advertised down to the 1/10th of a milliampere.

Joe S: The wiring was confusing at first, the black &red wires seem to be reversed. You need to look at the polarities from the amp meter's position in the circuit not the load or power source.

VI GuyVI Guy: I managed to reverse enginee the current amp feedback loop and modify to work correctly. I paralleled a 1Mohm resistor with the feedback resistor connected to the adjustment pot. See pics.

David J. Higgins: Set it up to use on a 3.3v, 5v and 12v supply but the Ammeter only works with 12v. Voltmeter works fine on all 3. All are linked through the same connections to the ammeter.

L Holman: Fit into my little battery charger great. It requires some electrical knowledge to hook it in place of a broken analog meter. Has good electrical diagrams on the Amazon product site pictures.
