Default Re: AVO Multimeter survey

Yes, don't forget our customers are Electrical Supply Contracting companies whose avos rattle around in the back of ladrovers, go up ladders and into substations! Definitely a hard life and frequent fryings !

The jewel on the cutout can be taken off a scrap one, we have loads, I've not heard it called a pallet-stone, we're not that fancy up north.

I'd forgotten about the open-circuit windings, I agree, you find a strange furry, slightly green-white deposit on the movement/hairspring arms when they get damp. Sometimes they get dropped into wells, sumps or chemical vats and this tends to damage them.

Good machines and I prefer the old 7 to the 8 because the needle moves faster when you want to fix a radio in a hurry.
