Fluke 189 with leaking surface mount supercap (also Fluke 287, Fluke 289)

I think officially, they're supposed to leak slightly over their rated lifetime, according to the product datasheet. :-\

That's disappointing. As Bravo stated, there is plenty of physical room, heck that meter is HUGE, they should have used a more suitable cap, with hopefully no leakage.

:wtf: :wtf:
I opened my up and guess what, its doing it too :(

I'm thinking of buying 289, but now i guess i've to stick with 87v. fluke 289 is disappointing.. leaking cap, the ghosting dot matrix lcd, the poor battery life. expensive usb cable, and lack of thermal probe compared to 87v etc.
other than graphing are there advantages for 289 over 87v? ok i can see loz and crest factor calculation.

The user interface to use the peak min/max in 189 is crap and capacitor test algorithm (for which one of the 87V's patent is for) on 87V is better, but my 189 is plagued with this leaking cap and the 87V is plagued with GSM interference susceptibility.
Great eh?

Looks like there are many variations of these Matshusita caps installed at Fluke DMM aren't they ?
Yours doesn't seem to have that brown goo sticking on it. Maybe that black shrinked plastic wrapper is protecting the outer shell ?
Is it dead ?
