Problem solved after changing interconnect spring of electrometer. Thank you PWD, Dheyaaldeen and Krishna for advice and comments.
Did you change the full interconnect spring assembly or just the spring at the interconnect spring rod?
Thank you in advance!

Hi
Interconnect spring replaced and problem solved.
In picture, you can see.Remove spring with rod and install new interconnect spring rod in electrometer...
Hi, I know this is an old thread, but I am having a very similar issue. I am wondering how did you know to replace the interconnect spring rod? How did you know this was the issue, and that it was not instead an issue with the FID board or the electrometer?
