AGC=75 SDM=7 DAC1=0-1000 DAC2=10-25
Ambient P=100.8kPa Tair=25.14C, Tdew=11.46C
zero air at 1000psi, CO2 in air 405.85ppm 1500psi Tdewspan=13.4
CO2 zero 0.9587 -> 0.9592 Offset: 1.72ppm
CO2 span 0.9796 -> 0.9758 Offset: 2.1ppm
H2O zero 0.7886 -> 0.7858 Offset: -20mmol/m3
H2O span 0.9667 -> 0.9532 Offset: 0.37C
Notes: The AGC values seemed high at between 70 and 75%. The internal chemicals were changed and allowed to run overnight.
