I've connected 1 gigaohm resistor in series with multimeter, and then measured milivolts. Everything is still invalid, voltages are same as without 1gohm resistor.
Actually, once the capacitor is charged, there is no more current
drawn, except the fraction of femtoAmpere due to residual
resistance of the insulating materials, which is way higher than
gigaohms.
In normal circumstances, no current should go through the 1G
resistors, except during the transient charging phase.

That would actually
cause what you are seeing. Big?question: Does it work when
providing bias voltage to the capsule? Remember?those are
literally?a 50-100pF capacitor?that we are charging up to
provide?a static bias too. They draw minimal current and most
is to the 1Gig resistor to ground that develops the signal.?

Hello
The internal resistance of my meter appears to be
955kOhm so about 1MOhm.
