Hello Spinlanders
Had our system powered down for ten days. CDCl3 lock signal fine before
power down, now NG. Since 1994, RG=35 worked fine. Now, require RG=45 to
see same trace as before. All cooling fans appears OK. Filters clean.
RG=35 OK for D3COD and DMSO-d6 but not for CDCl3. The lock system still
manages to lock at RG=35 but one does not observe typical lock signal trace
at that setting.
Has anyone had a similar experience? Is this a warning that the lock
transmitter is about to fail?
Any useful information will be collected and re-posted to the group.
TIA, Kind regards,
Lawrence
