Is your field value near its limit (-9999)? You may need to change your base
frequency. Although I typically only see this if a sample is locked onto
the wrong solvent.

Subject: [AMMRL] MeOD lock issues on Avance III TS3.6.5 #Bruker
Ok, recently all of my MeOD samples are failing to lock on my Prodigy TCI in
an Avance III running TS3.6.5. These samples lock fine on other instruments.
I can manually set the field and it will lock, but as soon as it locks on
another solvent
Ok, recently all of my MeOD samples are failing to lock on my Prodigy TCI in
an Avance III running TS3.6.5. These samples lock fine on other instruments.
I can manually set the field and it will lock, but as soon as it locks on
another solvent with another sample, it's unable to apparently find the field
automatically with MeOD. As far as I can tell, the lock phase is ok. 2H tune
is spot on.
Any suggestions?
