I still don't fully understand what this means for the voltage measurements of the NT1-a circuit. Do I need to add about 35% to each voltage measurement to get the correct voltage values?

Using Henry's procedures, you've been able to establish that the impedance of your meter is around 1M, not 10M as I had originally suggested as a possibility

The 35% reduction in voltage measured at that point confirms that the correct polarisation voltage is being applied to the capsule.
As Abbey suggests, time to look elsewhere.

Significant reduction in measured meter readings will only occur at very high impedance points.... like the capsule end of a 4M7 resistor!?
Measuring voltages at the various points suggested by Abbey should all return readings pretty much as indicated ( those points are all at a lower impedance )?
