Fluke 8840A - AC reading PCB upgrade
Thrasherg:
I know this was originally posted 3 years ago, but I hope some of the posters might still be around. I have reached out to Bill to see if I can buy one of his version 2 PCBs, but this was all designed to go in a Fluke 8840, I just inherited a 8842 from my retired father but it doesn’t have the AC option so I was hoping to populate Bills board and fit it to my 8842, both boards for the 8840 and 8842 are referred to as 09 boards so I was hoping they are the same board, but more checking seems to imply that the boards are very similar but not the same. Can anyone tell me the difference? What would I need to modify on Bills board for it to work in my 8842? Thanks for all suggestions and advise.

The difference is just that the header where the ribbon cable plugs in has two pins swapped. You can search the forum for this, the thread is several years back. If I were designing (or adapting a design) I'd probably set it up with two jumpers so that it could be configured either way.

I’m pretty sure I discussed the difference between the 40 and 42 in one of my repair videos where I worked on these units and got a ac board from a 40 and put it in a 42, this was several years ago now in one of my very early videos.
