[RASMB] Data acquisition failure

[Christine.Wandrey at epfl.ch]

Dear all,

during our last overnight run (absorbance, 200 
scans) a data acquisition failure occurred.
Message: "DAB: Radial rate failure"

From single scans I could identify that the 
failure happened at scans 133. Scans 1-132 look 
normal. These early scans fit well together. 
Starting with scans 133 a much wider radial range 
was monitored in the set range 5.9-7.2. It seems 
that a range of about 5.7 (cell material) to 7.3 
( also cell material) was monitored later.

My question: Does this failure occur suddenly or 
could the earlier scans already be affected?

Please find attached a pdf file, which 
demonstrates the scans before and after the 
failure. Note, that the sedimentation process was 
already finished when the failure occurred.

Thank you.
With kind regards,
Christine
