Colleagues: This is a question I'm hoping someone can answer. Today on our Mercury 300 (VNMR 6.1C) the following error message appeared during autoshimming: Acquisition error: error code 98 I was able to clear it by re-booting the console (i.e. big red button). I was wondering what that error code means, since it isn't listed in the command/parameter reference. Regards, Bill -- Dr. W. L.
