I am trying to figure out the schematics for a zero resistance ampmeter. I cant used a shunt or a clamp type meter since I am measuring no more than 15 mA. and the circuit is an electrochemical cell so if i use any other meter than a (ZRA) I will be playing chicken between voltage value and current generated. I got as far as figuring out that I need an ADC and an OP amp for the circuit. I would appreciate any help on this matter.
thanks
