Hi,
I am about to replace the 3V lithium battery of my Mixed Signal Oscilloscope Agilent 54622D.
The oscilloscope is 7 years old and the voltage of the original battery is now down to 2.97V.
Until now I have not seen any error message about this backup battery but I want to be
ready to replace it.
The lithium battery CR2354 is soldered on the system board.
Anything I should know before I replace the battery?
After replacing the battery, setting the time (RTC) and
then performing a self-calibration "User Cal" will be enough?
Any information is greatly appreciated. Thank you in advance.
Best regards,
Paolo

Thank you for the very comprehensive explanation.
We are ESD aware and we will be ESD safe.

Why not? I sure wish Agilent would just post this stuff to a website (without support) if they decide to kill the product. A lot of us live on slightly older test equipment and can't afford to buy the latest and greatest. (I can barely get my department to do that at work and they have a real budget).
It would be great to have all this old stuff simply available for use if Agilent decides to stop selling it. It might actually generate some sales if someone gets stuck with the older free stuff and discover there is a newer, better (paid for) solution.
Until now it was not necessary to replace the lithium battery because its voltage is still around 3V.
(This is the original lithium battery installed during manufacturing in November 2000).
The oscilloscope is powered on for about eight hours a day.
(The rest of the time the lithium battery must supply current).
After all these years the oscilloscope still works perfectly.
Thank you Agilent!
Best regards,
Paolo
