I'm building a cell checker and have a question about the test circuit design. I know just enough about circuit design to get myself into trouble. (I got through the electrical part of my college physics class with a lot of help from friends - that was a long time ago.) Luckily this is pretty basic stuff.

When a small panel meter is used for measuring PO2, the designs I have seen put a 10k load on the cell. Do you do the same when measuring cell voltage? Why?

I have spent a few hours looking for previous posts here about cell testers and have not found a "This is how I did it" post. Can anyone point me in a general direction?

Thanks in advance.
