Could not eject decoy sample using “ej” or BSMS keypad. Received “could not read spin rate” error in TopSpin, and sample status was at “missing” on keypad.
Was finally able to eject decoy sample after restarting TopSpin.
Cannot eject the decoy sample.
Wobb has periodic shaking slightly to the right of the center line.
Won’t lock.
Server will not display log in screen, only blank red screen.
Server is incredibly slow and won’t let me log in.
After locking onto ACN:D2O, signal was drifting and not staying horizontal. Topshim would not work in addition to this and kept saying failure.
Problem with lock during shimming. The lock light kept blinking and going up and down on the display. Attempting to shim did not alter the lock display.
Temp control below 19C, despite sensor 1099K. (DMSO froze, will not lock). Issue confirmed by another user.
Problem with temperature control. Set temp is 298 K, but sample temp reads 1099 K! Sample is cold.
