This zip contains an EDN article about precision voltage dividers. I've always wanted to play with something like this, and thought it would be a wonderful opportunity to try Circuit Wizard 1.5. I laid out my virtual circuit according to diagram 1b in the article, but lacking decade switches I used DPDT switches. It looks like I've laid it out properly, but the circuit doesn't simulate like it should. If someone who is familiar with Circuit Wizard would be so kind as to have a look and see if I wired it correctly, I would appreciate it. I've looked at it a thousand times and can't see what is wrong. (that usually means I made a mistake) Many thanks.
Is there something better than Circuit Wizard to play simulation with, but not as involved as Proteus? Something "between" the two?
