Default Re: AVO Multimeter survey

Pat, the cam screw has a crinkle washer under it's head which is normally enough to keep it tight- but every so often one comes loose and then the cam-rotor is free to rotate to any position, as no locating peg is provided..

Sometimes there is no obvious causation, sometimes it occurs because the radial contacts in the meter facia have suffered an arc, and a blob of metal has formed which obstructs rotation of the selector.

That Avo 8 sounds like a good buy.
