AV500 computer will not allow any users to logon and displaces and “Authentication failed” message.
unable to get good shimming by Topshim
Machine would not lock H2O/D2O samples. BAD!
Instrument will not eject dummy sample (either with BSMS keyboard, bsmsdisp, or manually entering ej). “Error: spin rate not detected”
After wobb command, tuning seems unstable.
Cannot lock on CDCl3 (~600 uL volume). Lock light on BSMS keyboard will not remain steady.
Not locking to CDCl3
Instrument will not lock. Indicates no communication with BSMS.
Still not really locking, signal to noise is poor, topshim is not working
Won’t lock
