The amp resolution is only 0.2a, and I agree not an issue.
The voltmeter portion being off by 0.2v is not acceptable, if I wanted it to actually display voltage, which I do not, as I have the calibrated 3 wire voltmeters in the same spot.
Thankfully one has the option to display only the amps.
How accurate the amps are is also a close enough. I am not sure which of my meters to trust the most but I did run 3 and 4 meters on the same load and loads from 0.8 to 2 to 12 to 25 amps, and they were all pretty close. Close enough. and more than good enough for my intentions( total alternator amperage), if I ever get around to installing the thing.
