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

<< < (34/64) > >>

Marvin:
This is interesting - I received my brand new 289 with manufacturer date of 30. Sept 2013 and it has calibration count of 2! It was not 100% official channel but a reliable seller from eBay and it really looks like it was brand new in box - and the box serial/manufacturing date stickers and all match. Could it be that it was manufactured on that date and then when the capacitor issue became public a week later they already refitted the fix in it or this is just some strange coincidence it coming out of factory with 2 calibrations? Can't open it up to see the soldering on the capacitor as the case is closed with a tamperproof sticker and I don't want to invalidate it.

Got to love friends who visit USA once and a while and agree to bring stuff over the pond in their bags :)

maybe the supercap is not an issue with your dmm..have you checked the board..?

It was bad definitely,it started with would not turn on all the time and by changing batteries would fix the problem for the while then  finally died.Board is super clean no damage of leaking and I installed new capacitor that was purchased form digi-key and recommended here on the board.

your best bet is to check with fluke directly! email them the serial number.

Anyway i don't think the super capacitor affects the cal. it's job is just to retain the dates etc as mentioned previously. 

Marvin:
If you open the case it is instant calibration void (technically that is, of course if you have a new sticker etc you can close it and put a new sticker on it) - that's what I'm thinking - the manufacturing date on the box match the calibration date in the unit but the count is 2. Maybe they opened it before sending it out and fixed something? So it is officially factory calibrated but 2 times.

BravoV:
Marvin, an intriguing new Fluke 289 with 2 cal counts.

Any chance taking the photo of the tamper proof seal, or does it look similar to this example here, and also whats the firmware version it has in there ?
