Re: AVO Multimeter survey
It has been sometime since I have checked in here, however I have just acquired a Universal AvoMinor and feel duty bound to record its credentials, i.e. No.2140-35. It came with its original small, tatty but worthwhile, book of songs and probes and I would guess is of 1935 vintage or earlier. Advice would be appreciated.
It is OK accept for an open 500 volt multiplier and lack of wiper pressure in respect of the ohms adjuster. I consider that the former is best left as, is rather than add something non standard, but would like to fixe the latter problem if possible.
The mechanical set up presents real problems and I can not see how, even if fully stripped down, removal of the wiper assembly is provided for. I have given thought to "wiping" the contact blade, as one would treat a 3,000 type relay contact, but the lack of room appears to rule this out. Any ideas would be very much appreciated. Trevor.
