Got the error that topshim failed twice due to “losing too many points during fit”
I got kicked off the system while my sample was shimming, and when i logged back in, topspin said “no acquisition” so I decided to start over. I ejected and re-injected my sample and attempted to atma but received an error message saying “acquisition is already running”. Typing “stop” and retrying “atma” resulted in the same error message.
Login screen does not appear, so I cannot log in.
Black screen instead of login screen
Still not locking to solvents properly.
Not locking onto C6D6
The BSMS keypad cannot eject the sample, and using ej on the keyboard also does not eject the sample.
heater not regulating temp – temp at 283 K
The buttons of the BSMS keypad do not respond, and the sample cannot be ejected using ej on the computer, so I cannot use the instrument.
The sample without spinner has been removed from the instrument. The system is operational as usual.
The system has been restored to normal operation.
