calibrating for new TPS on '87

I need to replace my TPS and I know something needs to be recalibrated. I've been all over the net and cant find anything concrete. I heard it has something to do with taking measurement with a multimeter and adjusting some screws on the manifold. Can anyone help me out?

BTW, I do agree with the general consensus: the 98 is a awesome car. 136K and going strong. No major engine trouble ever, and very little rust, which is damn good for northern Illinois.
