9 Troubleshooting
ATM Error
• If the ATM does not work or returns an error, the ATM server software may need to be
restarted. To do this, simply quit TopSpin and restart it.
iProbe HR-MAS Errors
• If the communication with the MAS-Unit fails, reset the MAS-Unit and restart TopSpin.
• If no wobble dip is visible: Make sure the stator is not in the eject position. If it is, flip the
stator into the insert position by checking / ticking the insert button in the MAS display.
• If there is still no dip in the wobble curve, the correct routing of the current experiment
should be checked with the command edasp .
Problem with iProbe in TopSpin
• If a problem with TopSpin occurs during the iProbe installation, use the command
savelogs to collect information about the installation setup and send it to your local Bruker
support.

Poor Line Shape
The magic angle is very critical for good shimming and line shape.
• If the line shape has deteriorated: Check the magic angle setting.
NOTICE! Sample preparation is equally critical. The presence of air bubbles inside the
rotor or leakage of the sample degrades the quality of the spectra significantly.
