divide by 20: 299 (<- oops, div-64: 199)
Oh yes, that was a typo :-)
Good work !
Thanks! I guess you are right about the last digit, though, a multimeter is always only practically precise to the last digit. We had a long discussion about this issue during our practical studies at the university. If you have a multimeter that has a .1 resolution, do you say the approximate error is .1 or .05? It's the same kind of thinking behind it :-)
I think I'll keep the trim pot in there, though, because I am not sure if I will get a decently precise 6 Ohms shunt. Maybe use resistance wire with 33Ohm/m and take 18.2cm or so. Or are there better sources for these shunts?
Now I have to figure out a practical way to get the 5V symmetric voltage for the op amp. Thought I'd go for the standard LM358 with maybe a 7660 charge pump?
