As we are talking about supercaps, you can use the following pdf (datasheet) or pictures to estimate the lifetime of your supercap. based on this equation mine should last for ~6.5 years. https://www.mouser.com/ds/2/88/EDL-19670.pdf |

The Supercap failed on my Fluke 289 so I sent it back to Fluke in the Netherlands in 2016 under an RMA for a warranty repair. I think it took about a week round trip, I wouldn't have known the Supercap was the issue if it wasn't for a thread that year on here. Every Friday I check all my batteries,replace/recharge as necessary. I also power on anything with a Supercap Friday and Tuesday (though I assume the 289s supercap is energised direct from the AA cells from before the switch. I noticed last Friday the time needed reset and the personal details have been wiped. Changing the supercap is a warranty repair so shouldn't cost if still in warranty. The repair won't affect calibration and Fluke normally won't do a new factory calibration. |

So today I finally get around to calling Fluke's repair department here in the US about my two 289's that seem to have the supercap issue (both forget the date and time when the batteries are removed). I learn that the 289's have a 10 year warranty. The warranty repair does come with the non-data type calibration. Maybe their policy on calibration with repairs varies from country to country.. Also: I asked - when 289s go back to Fluke for repair you don't need to include the test leads, batteries, or any case. Just the meters. Shipping both via FedEx Ground today was $18. If I had fully insured probably would have been more like $26. Lol tried UPS first and they literally could not process the return address. Pffftt. There are some building numbers in front of part of it, and the UPS system didn't show that exact building. That is why I stopped using UPS for outbound a loooong time ago. I hope this information helps others! |

I recently had my 289 in for a faded display issue in low ohms and possible supercap issue. Spoke with Fluke TS to confirm the work that was performed and the rep stated no pay, no calibration. I received the unit back yesterday. Fluke replaced the mobo and included a calibration certificate. All expense covered under warranty except shipping to Fluke. Changes from my original unit Board ID was 3 replaced with 5 Build date 6/2010 replaced with 11/2017 FW v1.16 replaced with v1.41 I purchased this unit last month on fleabay.. forgot to tell them I wasn't the original owner :-DD |

I got into one of those rare lab moods early today |O and decided to takes my chances and de-solder the supercrapacitor from both the 189 and 289, with no intention of replacements same or better, and damn the torpedoes... >:( Got everything set up ready to unsolder, ensure no ESR drama, thinking about somehow safely discharging any residual charge from the supercaps first, and... WHOA! wait a minute! ??? I went another way: >:D I CAREFULLY used my sharp sidecutters to cut the top metal tab off the supercap, slowly lifted back the supercap to about 90 degrees max, bent it back and forth a few times, supporting the back so no pressure on the PCB solder area, till the bottom supercap tab snapped off clean Cleaned up with isopropyl alcohol > Job done :clap: Both meters working perfect, set their clocks, and no more suss supercrapacitor issues to think about, or rant on and Fluke bash at 189/289 posts FWIW: the supercap tab remnants can be unsoldered any time in the future if I (no chance! :-- ) or the next owner wants to wack in a supercap, and resume the saga I just ended i.e. No Fluke was harmed by this procedure to remove a malignant tumor :phew: Happy Fluke Camper again :-DMM :-DMM |
