Hi,
could be a short of the electrometer and/or the spring. try to uninstall/clean the spring and check again. Could also be a problem on the signal board. If the error persist i suggest to call Agilent service to replace/check electrometer/signal board.

Hi
Another reason for this problem could be because the detector temperature was too low and water condensed inside the detector and shorted it. You should clean the detector and checking for the presence of water. This water comes from condensation from the hydrogen flame in FID.

Thank you for reply...May i know that electrometer of 6890N and 7890B is same or not...

OR FID signal interconnect assembly of 6890n and 7890b is same or not...
7890B
FID electrometer G3431-61815
6890N
FID signal board G1531-60010
electrometer of 6890N and 7890B is not same
