Dear AMMRLers:
Recently the lock signal in our 400 MHz Bruker Advance DMX has been
keeping lost after locking for couple of hours, and got the message "
BSMSInitial value lost, restore with rsh command" . We did rsh, but we
got the lock signal lost again and the same message appears. We then
thought it might be due to the bad shim CPU, so I got a new shim CPU
from Bruker. After putting the new shim CPU in, can't get any lock
signal, meaning no any deuterium signal detected by the machine.
Messages like " Caution: lock frequency ", "E:60 BSMS Timeout " appear.
I know our machine is at 400.13 MHz originally and now at 400.06 MHz. I
did "asl" command, but still failed to get any lock signal.
I was wondering if anyone here has any suggestions? I would very much
appreciate your help.
Sincerely,
Yunqiao Pu
