Everyone is aware of the technique of running multiple turns of wire through an ammeter current probe to place the measurement within the meter scale for reasonable accuracy.
What's the equivalent procedure for multiplying an electric field measurement/ indication for a non-contact meter?

it's not really the same thing, but turning a static field into AC is a useful trick too.

Right- I'm familiar with that technique. Put the signal in a very narrow band using low noise, offset and drift electronics.
