Constant spin rate read errors made it almost impossible to inject/eject samples.
When I was trying to take 1H NMR at 11:40 AM, topshim kept failing. The error is “FieldMap – signal to noise is too low.” This happened even after I ejected, re-locked, and tried again. And also after I tried “rsh stdpabbi”.
Topshim command failed due to apparent low signal-to-noise ratio.
When trying to eject dummy sample I am getting the error “spin rate read error” repeatedly
When I tried to run “topshim” I was prompted with a message saying “Please state, how the shim system is attached to the shim current boards…” and was required to choose one of two options in order to continue.
Topshim command failed due to apparent low signal-to-noise ratio.
ATMA doesn’t work. The “Dip” in the Wobble curve moves too much for the instrument to tune/match properly.
