This used to happen on my old 252, but with a physical chart recorder
connected directly to the mass spec I could see that the signal was still
present coming out of the amp. Rebooting the computer reset the data feed.

Subject: [ISOGEOCHEM] signal problem

I've run into a problem I have to admit, I've never encountered. We lost
mass 44 voltage last night on our 253, this in the middle of a Kiel run, but
have retained M45 + M46 signal intensity. Can anyone point me in the right
direction as to what the problem might be?

Many thanks
