Subject: | ENA/TRACEGAS/C1 - baseline (or span) shift of ~3-5% |
DataStreams: | enaaoscoC1.a1, enaaoscoC1.00, enaaoscoC1.01, enaaoscoC1.b1 |
Description: | Following a power outage, the baseline signals for CO, H2O and N2O all shifted approximately 3-5% higher. It doesn't seem this is an atmospheric change at this time. Ironically the next standard addition calibration was spot on (previous ones had been 3-5% low). Ironically, communications to the mass flow controllers running the automatic calibrations failed after a single post power outage calibration. While the reported data is affected, it will be difficult to tell how much. The September data set should shed light on this. |
Suggestions: | Consider data to be 3-5% low prior to this period? |
