Review on Karcy Rectangle Ammeter Circuit Measurement by Joe Glass
I've always preferred analogue to digital.
I would like a little more accuracy. Although I've only tested it with a 3 amp load, it's accurate enough for my purpose. The needle is about 500mA (1/2 amp) when off; If it's set to zero when off, that's 500mA under load. So three stars, not five. 250mA (1/4 amp = 2.5%) is within its accuracy; 500 mA (1/2 ampere = 5%) twice that. The update gets stuck at 2 amps and doesn't move. There are pictures and videos, for some reason you can't download them
