Which ranges ?
Are you aware of the SDM Cal site Defpom made ?

Yes I am aware. But this method is useless if you don't have a calibrated source like his Datron.
I know that after one year any DMM need calibration, but the ideea was that SDM3065X left me with the sensation of not being in the same league as Keythely,Fluke or KS. This is why I  headed to 34465A. But this topic make me anxious about ... :-\

Yes Siglent doesn't use aged references so they can drift outta spec. IIRC some owner here mapped the drift and found it almost exactly matched the LM399 datasheet drift spec.
You should contact Siglent in Germany as I believe they have a universal calibrator that can bring yours back to factory accuracy in a flash. Actually I will check on this as I know the US branch has one.

I will PM you to not continue to be off-topic.
Sorry, @OP.

When I bought a 34465A last summer, I got the 5 year extended warranty for an extra $82.  At that time similar 5 year coverage for a DMM6500 was quoted at $357.  I have a hard time believing Keysight is really experiencing massive failure rates on a product while selling extended coverage at such a low price.

Why should customers suffer over a product defect?
It takes a lot of time getting the RMA, customs docs, shipping info, then there's down-time and the repair costs sending in the brick for repair, assuming it's not declared obsolete.

This guy's 34461A died after 6 months in storage, sounds just like the FLASH aging/corruption issue, a 2015 (at 4 yrs old) https://www.eevblog.com/forum/repair/keysight-34461a-179388/
At some point the affected models, years and serial numbers will have to be known. Your extended warranty, is it "to" or "additional" 5 years to the standard 3 years?

The "professional use only" shitstorm (almost 33,000 views) I wonder if it's to elude consumer protection laws which would apply here?

That is a weird service note.
The mounting of the front panel has not really changed in years.
If they have not made the mounting holes very large, I can not visualize how the front panel should come loose.

But then on the other hand, these 4 screws should probably have been installed since the early 34401A

Ive had a 34461A come back from Calibration at Keysight, opened the bag to find the front panel loose on one side.

could see the plastic could have just be squeezed a bit and pushed back in, but we sent it back to make sure they were aware of it. But that was back end of 2021. Not seen any since, but most of ours are still in their first year of calibration. so will see when we send them out for the next rotation.
