Re: Figured you'd provide a BS response..I guessed right..

JC: ""Jneutron, you DON'T need full resolution of settling time to .01% WHEN you are looking at the results on an analog oscilloscope.""

And that is because of what?? Because of the range? Because you don't saturate the scope inputs? Why would a digital scope be any different???

You're amplifying a difference signal...if the difference saturates the IA, forcing the IA to recover from an out of bounds input, and you're looking at a .01% error, well? You stated in your paper that the residue signal ranges from 10% to .01%..

And your test signal is way too slow for testing wires, so questions of recovery are important then...not for your 1uf caps..

So why are you following this red herring? to divert from the real questions? The IA issue is long dead, answered by you a while ago...give it up...answer the real questions..

JC: ""Furthermore, we eliminated extra inductance compensation in our final paper, BECAUSE we deliberately slowed the signal down and deliberately bandwidth limited the test signal SO that it did not show differences in inductances between capacitors.""

All you did was try to eliminate the lead inductance..not the inductive effects within the capacitor...

JC: ""I mentioned this in a follow up letter to Dr. Hawksford's concern about inductance:
" 'HFN' July 1986 p 29 "I would like to clarify one issue in Malcolm Hawksford's critique of our article.(2) The equations he developed for the differential capacitor test include inductance as a potential error contribution. In some cases we did find inductance to contribute to the error signal. In order to balance the inductance, I have added as much as six inches of wire to one polypropylene capacitor in order to match the inductance of the other polypropylene capacitor under test.""

You neglect two other sources of inductive effect within capacitors..a 6 inch piece of wire is a rather simplistic model, and is meaningless for larger capacitors..ones wound with many turns of foil.

Lose the herrings...stick to technicals..

Cheers, John
