Subject:
SGP/ACSM/C1 - Unexpected instrument shutdown
DataStreams:sgpaosacsmcalC1.b1, sgpaosacsmC1.b1, sgpaosacsmC1.00, sgpaosacsmC1.01, sgpaosacsmC1.a1
Description:
There was an unexpected shutdown of the ionizer, vaporizer, SEM, and inlet valve, possibly 
caused by a power outage. This resulted in incorrect data values.
Suggestions: 
Do not use data
