AGC=58 SDM=7 DAC1=0-1000 DAC2=10-25
Ambient P=100.36kPa, Tair=18.6C, Tdew=4.76C
Zero Air at 900psi, God CO2 421.22 at 1200 Tdewspan=15.97
CO2 zero 0.9586 -> 0.9578 Offset: -2.8ppm
CO2 span 1.0023 -> 1.0031 Offset: -0.22ppm
H2O zero 0.7382 -> 0.7355 Offset: -17ppm
H2O span 1.0109 -> 1.0253 Offset: -0.27ppm
Notes: The H2O span was unstable. Adding water to the dew point generator seemed to improve the situation but still variable.
