I have been working on the fluke some more, I have been going through its basic calibration procedure (doing a video it of course).

I can see that TP5 on the oscillator control board is noisy, so this could be a clue to where the noise is originating.

As it is a closed loop system, I will need to inject my own signal at some point of the circuit to see if the noise is before or after that point.

So my house which was flooded on January 5th has finally started to have work done to repair it.

House has been gutted, now I just have to wait whilst it is fixed.
