I'm wanting to built a DC volmeter from a moving coil ammeter. I have all
the info and can calculate the series resitstor I need to make a (say) 1-20V
meter. It's an automotive use. What I would like to do do is offset the
zero so the zero reading is say 8V and the maximum 18V. I can't for the
life of me find a simple circuit that will work, though I knowq I have seen
them, using a regulator. Can anyone point me in the right direction please?
Thanks
