content: Mentioned elsewhere on EEVBlog, this was rescued from it's hiding place of many years. The battery was corroded but since it wasn't an alkaline type I don't think the dreaded rot has spread.With a new battery the meter is as dead as a dodo. I haven't determined if it is actually dead or if the display is just not displaying, as these types of display sometimes do. I had intended to clean it up and fix it, but on reading another thread I realised that a) I have far too many meters to play with, and b) I seriously dislike this style (which may be why it managed to get lost for all this time).I haven't cleaned it up or done anything to it other than try a new battery, so it's not a failed repair or bodged cleanup - you will get it just as I found it at the back of a rarely used shelf. Nevertheless, I can't recall where it came from so it may have been worked on before I got it, although I am 99% sure it used to work.Naturally, I would prefer to dispose of this with someone who would fix and use it rather than flipping straight to Ebay as a 'vintage Fluke'. Yours for the cost of shipping (probably £4.45 to mainland UK).

content: If I was in Europe I would take it gladly. I've been for years to try to get one just to say I own one.Repairing one would be even better.

content: Looks like one of those Fluke meters that can measure conductance as well. Apparently this feature makes very high resistance measurements possible!That's the kind of repair challenge I like. But I bet shipping this to Canada would be prohibitively expensive...

content: That's definitely a broken display, you can tell by the colour. If it's completely black when it's off it's toast. But looks like a common type without any additional characters, so it should be easy to replace it.

content: Well, how much would it be to Italy? I've successfully repaired Vinegar Rot on an LCD, so maybe I could try it.

content: I would second the opinion on the broken LCD. My 8020A has (luckily) a still intact LCD, which is shining silvery when off.There is lots of documentation available which special types the LCDs back then were, and here in the forum in the 8060 thread drtaylor also elaborated a bit about the displays, which means that they were back then in the 80ies a custom job.Replacement with an original part is diffficult, but there are other approaches:http://mrmodemhead.com/blog/fluke-8020a-lcd-replacement/https://www.sbprojects.net/repair/fluke8020a/index.phpApart from that, the DMM probably only needs some good cleaning, especially around the knobs of the switches (some good actuations also will help to get rid of some buildup of oxidation).After that, if nothing else happened to that device, there is a good chance that it still is within spec- my copy was probably never used much, got a working LCD, and after some heavy actuating of the switches it was working well again.
