AGC=99.2 SDM=0 DAC1=- DAC2=-
Ambient P=100.16kPa, Tair=27.11C, Tdew=6.82C
Zero Air 369068 at 1100psi, AMP CA04396 408.97 at 750 Tdewspan=15.99
CO2 zero 0.892 -> 0.8911 Offset: -4.4ppm
CO2 span 1.0073 -> 1.0171 Offset: -5.12ppm
H2O zero 0.7263 -> 0.7260 Offset: -2.4ppm
H2O span 1.0104 -> 1.0118 Offset: -0.02ppm
Notes: First lab calibration since factory calibration. I manually typed in the new coefficients and zero/span values. I saved a config file then opened it in a text editor and changed the calibration dates, standard gas values and WX coefficient. I saved and uploaded this config. This IRGA now has the SD* temperature coefficients and its signal strength was reset at the factory. Our zeros were lower than the factory calibration so I calibrated and saved a new lab calibration config file.
