Hello Dr. Kirkby,
This would work in the case you can send it via some company. Keysight
is not working with private persons anymore and I didn't find other labs
that work with private persons at least in the EU.
I tried to get some calibration services for a few power sensors and
nobody wanted to work with me as a private person. Also, I tried to
order from them the test leads for a multimeter and they requested a VAT
ID and a company name. You don't have that you cannot order services or
parts.
Best regards,
Razvan

I did it ! I replaced the memory battery in my 3457A.
My used 3457A was built in the late '80s and still had its original
lithium battery, with a 1989 date code on it. This battery obviously
needed replacement.
Another option is to ignore trying to save the calibration constants,
replace the battery and send it to Keysight and let them calibrate it.
Then it will be as good as you will get it. I did that, and they
replaced the battery. There were before and after measurements - they
made no attempt to save the constants. So everything was better after
calibration. In contrast if you send it there are calibration constants
about right, if it's in spec they will not adjust it. In contrast, by
putting them all wrong, everything needs adjustment.
