I took the cover off the oscillator and checked the resistors and as I predicted some of them are actually high and out of spec the worst of these being on the lower ranges.
The worst were the two 820K ones on the lowest range. These were reading over 1 meg.
I have not yet fitted the new ones due to a dinner call although I did get time to select them from stock parts.
My big Fluke came into play in order to double check my every day DMM.
The access to replace the resistors is easy enough so it is not a lot of bother to sort out.
