Fluke 189 with leaking surface mount supercap (also Fluke 287, Fluke 289)
Tasman:
Just had a look inside my 187 - it does not have one of these capacitors.
Seems like they are for the logging memory backup. Glad I didn't cough up the extra for the 189. :)
Svuppe:
Ahh, good news. I was going to open my 187 tonight, but thanks to you I don't have to.

The original Xbox had the same problem with its supercapacitor... you should definitely replace it as it can cause rather serious damage to the PCB if it bursts: http://dannygalaga.com/xbox.html
There's also a rather strange paragraph in the datasheet given earlier:
--- Quote ---7. Brown extraction
Brown extraction may occur around the sealing part depending on use conditions. This extraction is electrically nonconductive.
Therefore, it does not infl uence in the electric characteristics.

I will probably go with that one.

Actually, with Digikey's shipping, you might as well buy a dozen and sell the remaining caps off on eBay for $6.88 each. ;D

Interesting, I missed that part.
If the brown goo even grew into like Mike's is harmless, then its fine, but at JohnDee's its leaking and ruined the board and surrounding components as he claimed, wish he could share some close up photo here.
