[volt-nuts] Vibrating reed electrometers

[ed breya]

Another thing I noticed in these instruments - the highest R value used 
is E12, even though decades higher would have been appropriate in 
certain ranges. It shows that was about the practical limit for somewhat 
decent precision and cost. Filling in the desired higher ranges had to 
be done by adding complexity like more gain elsewhere, and writing the 
specs accordingly.
