Would not tune and match (took 5 minutes attempting to match but never succeeded and timed out).
Would not do the topshim command. The error was signal to noise too low. The user before me (Jon Kephart) commented to me that when he was using the instrument it would not tune the first time, but after quitting and restarting, he got it to work fine. ATMA was fine for me.
ATMA extremely slow and could not lock on solvent (DMSO).
Could not log on — would say “incorrect password” even when I was positive the password was typed correctly.
for the last week or so AV300 does not lock on CDCl3 the first time I try to get the solvent lock. when I pull up the lock display its clear its not locked even though it says “completed”. When I retype “lock cdcl3” it works no problem.
Computer froze after logging in
Tried to eject decoy, got an error that said “spin rate read error”
Still kicks out users after signing in
Immediately upon logging in the computer automatically logs me out.
