Temperature change takes extremely long. Heater not optimized?
Same issue as Chang-Uk. Lock wouldn’t open after typing lockdisp, got a series of error messages:
Error opening spect:/dev/tty03
locked by process 21151
then
Unable to get data from lock server .128.95.172.212
Fail to open lock display. Wobb is not working.
Wobb not working on AV301 and AV500. Error message: wobble signal too weak with RG=46341.0
The tune and match knobs for carbon seem unresponsive. Unable to wobb.
The lock issue has been resolved. Lock should proceed as normal.
Could not get spectrometer to lock on DMSO-d6 sample.
Tried to lock multiple times on a CD2Cl2 sample without success. After manually locking and it seeming like it was successful, shimming was non-responsive. Tried locking on a separate C6D6 sample and ran into the same issue.
Couldn’t log into the program. Error message said “authentication failed”. Was able to log onto the 301 and 499 though.
Wobb not working. Attempted to run a 13C NMR experiment. Was able to lock but not to wobb.
“wobble signal too weak with RG=46341.0”
