When performing atma or atmm got the error message “channel cannot be set”
System is restored.
Same as the last two… also my sample is currently stuck in the instrument.
sample won’t inject. spin rate read error. ij and panel both do not work
Sample wont inject, constantly giving a spin rate read error, can’t turn off lift gas flow.
“phosph” threw an error, so I started a 31P experiment from another file. The wobb looked good for 1H and 31P. The 31P signal did not look normal, and transformed into a spectrum with a wavy baseline.
During topshim got a ‘BSMS failure’. Control panel does not work and the lock display is no longer showing and ej does not work (no air). Sample is stuck down.
Also getting that topshim failed because lock is pending. Solvent is DMSO, attempted a proton scan.
Topshim failed. It says lock is pending.
