AGC=104 SDM= DAC1= DAC2=
Ambient P=100.40kPa, Tair=23.32C, Tdew=12.40C
Zero Air at 500psi, God NOAA CO2 421.22 at 500 Tdewspan=16.00
CO2 zero 0.9416 -> 0.9427 Offset: 0.16ppm
CO2 span 1.0000 -> 1.0156 Offset: 8.39ppm
H2O zero 0.8318 -> 0.8333 Offset: 0.23ppm
H2O span 1.0039 -> 1.0150 Offset: 0.23ppm
Notes: First calibration before field install - new Bouldin alfalfa site. Factory calibration (previous) used 700+ span CO2. Updated software on box AIU-1568 to version 8.0. CO2 zero and H2O zero offsets were not recorded immediately, but were filled in from memory.
