Unstable lock on CDCl3. The lock field and phase need to be manually adjusted before using the instrument. This issue has persisted since at least 13 Nov 17.
Not locking on CD2Cl2 – lock command finishes, but blinking lock on/off light. My sample is homogeneous and has an appropriate amount of solvent.
Tried locking on CDCl3 and the lock button wouldn’t stop blinking even when the online system said “finished.” Tried shimming and the red/green lines would not change levels.
I can’t access data from the DRX499 on the ftp site.
Lock on/off button on console is blinking even after topspin says lock is finished.
The system has been cleaned up and Topspin should functional normally.
Topspin wont open
Topspin didn’t open
Topspin won’t open.
Topspin won’t start.
