UPDATE ! AV500 – SYSTEM WILL BE UNUSABLE FOR NOW
Faulty channel 3 is not yet operational and available options are being explored. If a part replacement is on the cards, we may have to wait a few days. In such an eventuality, I will release the instrument with the caveat that we have to shim the sample by hand, as in good old days. […]

ALERT ! ALL NMR SYSTEMS RESET AFTER POSSIBLE POWER DISRUPTION

All the log posts of today morning are related to this. The systems have been reset to their usable condition now. NMR Facility Manager 9/18/2017

ALERT ! SYSTEMS RESTORED – AFTER POWER FLUCTUATION
The apparent Lock anomaly noted with AV300 has also been found with AV301 and possibly DRX499. Apparent line voltage fluctuations were reported today and similar to last week, that could be cause of the Lock disruption. The 300-s are restored to normal operation as we speak and I am checking that DRX499 is functioning as […]
