Tuning on C was very very distant from starting value; I had to change the second slider from 7 to 6 to get any sort of match.
Cannot tune/match on 13C
I am not able to wobb 31P. As well, the lock for CD2Cl2 does not seem to work (I get an error when I use topshim, and when I try to shim manually, the lines do not change).
Having a hard time matching on 1H
Wobb has very noisy lines on 31P, and changes frequently.
Currently. the 500 is experiencing issues reporting the proton signal. Until the issue is resolved, users will not be able to get spectra on the av500.
Tuning and matching on the 1H and X channels are functioning properly.
cannot wobb the 31P.
cannot get a stable wobb signal on 1H, it’s constantly moving
Cannot Tune/Match on 1H
