Last calibration: 2020-08-27
AGC=101.8 SDM=0 DAC1=- DAC2=-
Ambient P=100.4kPa, Tair=29.0C, Tdew=1.3C
Zero Air at 500psi, AMP CA04396 408.97 at 300 Tdewspan=20.0
CO2 zero 0.9184 -> 0.9190 Offset: 2.3ppm
CO2 span 1.0118 -> 1.0059 Offset: 3.03ppm
H2O zero 0.9012 -> 0.8984 Offset: -17.2ppm
H2O span 1.0121 -> 1.0033 Offset: 0.19ppm
Notes: Flow rated larger than usual - 2lpm instead of 2cfpm. Dew point generator problems before cal - dew point stuck at 34 instead of 20C. The dewpt gen was fixed an ran at 20C before starting H2O span but dewpt initially jumped to 25C but steadily declined to 20C. I double checked CO2 zero/span and H2O zero afterwards and they seemed fine.
