Good News & Bad News:

Bad News - Your 3468 is likely out of calibration. It'll still work but the readings will probably not be accurate. And, the CAL RAM battery could be on it's last leg as well.

Good News - You can save and restore the calibration factors to facilitate changing the battery.

I have checked the battery. It has 3,0 VDC. The calibration procedure is to heavy for me. I am a mechanical engineer , in other words a hammer thrower. I am not able to manage it. And how could it help to save the actual calibration data if these are not okay? I know a company in Germany that has calibrated an old FLUKE for me. I will ask them for help.
Thanks a lot for your help. Now I understand that something is wrong with my HP-3468A.
PS.: I have also asked the seller, an Italian company for electronically devices for help. Their answer: When no signal is applied it is normal for the display to show strange values.
