Thanks to you both.

The meter reads only on Ohms and Ohms x100 and there are no DC or AC readings for any current or voltage range, including the HV terminals.

I have a downloaded AVO Servicing Manual (in PDF, 23 pages) but am unsure if it is the correct one.

The meter is a model 8 Mark 5 and is labelled:

P/N 5170-211
S/N 13995
8V/5/74

I'd be quite happy to open it up, and would be grateful for any assistance with that and repairs. A dirty or bent contact sounds the most likely problem.

Cheers

Roger
