Yes, I can see these are tricky.

I wish my high-resistance meter had a triaxial BNC. It has a triaxial
cable, but screw on. I can't find out what the connector is.

I can't see how to use a voltage divider with the electrometer. If you know
how, please let me know. I don't have an electrometer, but will buy one.
Someone in the UK has one he is going to dig out the garage, so I will
probably buy that.
