I am experiencing unusual problem. As in the subject, my sequence stops right after attempting to run and MS parameter 64.256 error is logged in the Current Logbook. I have never seen anything like this before.
I did some maintenance before that happened. I cleaned the ion source as always. When trying to tune it later on, tuning stopped few times showing an error of MS parameter 64.256 being out of range. I managed to finally tune it using a previous tune file as a template, but the tune report was not great. High EM voltage suggested me to replace it, and I did it as it was old anyway.
I managed to obtain a good tune this time but that was the end of my luck. Happy to run a calibration, I proceeded with starting a sequence and then it refused to run.
Can anyone suggest what to do? I have attached few recent tune reports for better understanding.
Many thanks in advance.
