Subject:
SGP/CCN/C1 - Incorrect temperature gains or settings
DataStreams:sgpaosccnavgC1.c1, sgpaosccn100C1.a1, sgpaosccnavgC1.c2, sgpaosccnC1.a1, sgpaosccnC1.00
Description:
New software was installed with instrument and temperature gains didn't transfer 
correctly. Super saturation values are incorrect and instrument tended to overheat in an attempt 
to reach set point values.
Suggestions: 
Do not use data
