Dear all,
Looking for sage insight into current issues with a Bruker AVII and RT probe.
In May we had a lock dropping occurrence (see attached photo). A console reboot
solved whatever that issue may have been.
In August we shutdown the instrument in prep for a tropical storm and now the
issue is back with higher frequency and came along with other problems.
After repeated console power cycles, repeated Topspin cycles, cf, and ii,
several issues are occurring:
*
Invalid probe parameters found. This was not changed prior to shutdown. edprobe
detects correct probe. Action: cleared the cable connections, set the
connections again, save. Seems to be ok, however see next bullet.
*
Error when testing 2H: 'channel can't be wobbled with this probe- no channel
for : 2H'. This should not be true. We were able to tune and match 2H during
the May issue.
*
When reading in a saved shim file (rsh), the lock starts dropping somewhat
similar to a gradient experiment. Action: rebooting the BSMS keyboard fixes
it - until trying to read in a shim again.
*
After a reboot, sometimes we can shim and run an experiment. But sometimes
lock drops during shimming, Or drops as an expt starts, Or drops
while the system is idle.
*
Optimizing 01 in gs works intermittently.
*
Water suppression and resolution are terrible.
*
During cf, occasionally receiving 'Error reading BOOT firmware version of
BSMS-Unit: no error' and 'Error reading board config of BSMS-Unit, unknown
command'.
Appreciate any advice or guidance offered.
Best,
