I have been tasked to get in shape a Shimadzu GCMS 5050. This instrument hasn't been used for a couple of years. I cleaned the ion source and the system pumps down fine. However, while trying to autotune I keep getting a “mass calibration error” message. The manual tune is possible (using PFTBA, see picture) but I simply can’t get rid of such an error, considering that my manual tune is good.

Any thoughts? Thanks a lot for your help.
