Alistair,
Thanks for the reply. Indeed James at Techniques has now said the miloemeter failure is a common problem usually caused by damp. He is going to try a quick fix with a hairdryer. If that fails then it will go off to a specialist instrument shop. The good news is that is it sounds like a sortable problem. Not sure what I would do without this forum and Simon at SIFAB and James at Techniques.
Thanks
Graham
