Fluke 189 with leaking surface mount supercap (also Fluke 287, Fluke 289)
mimmus78:
I think this "built" date is relative to the build date of the boot loader (when it was compiled) not to the meter "motherboard".

--- Quote ---That is weird, what is the current cal count ? If its still 1 (one), then this must be strange, manufactured in 2010 but with 2013 factory cal date is quite long time. :o
Are you sure you're not mistaken by the bootloader's date at the info screen

Calibration Date: 25/04/13
Calibration Counter: 1
Board ID: 3
The rest is same as per your screen...
|O I'm DOPE!!!
The 'built' part is for the 2 liner... "ARM bootloader..... built 08:38:05, Jun 25 2010" :)

Well, just see at the bright side, at least you now have few months to enjoy the shiny ultra cap before its starting to poo out around at the outer shell like mine. :-DD :palm:

after watching Martins video
I had a look in my 289 and it is also having some leakage on the capacitor :--
Although that looks like an easy to fix issue, I must say, that is not what I expected to see in my Fluke.

Looks like I am cracking open my 289 this weekend!
CSmith:
I opened up two of my Fluke 189's and two of my Fluke 289's, and their supercaps were all in pristine condition despite the passage of time, so some of the supercap's must be up to the challenge. I wonder if it is a supercap manufacturing quality issue such that there were bad batches, or whether there might be environmental influences that help spur them to go bad.
