Title: Calibration
Notes: Last calibration: 2023-02-23 AGC=100.4 SDM=0 DAC1=- DAC2=- Ambient P=100.6kPa, Tair=22.15C, Tdew=6.27C Zero Air at 1400psi, AMP CA04119 524.77 at 1250 Tdewspan=16.0 CO2 zero 0.8849 -> 0.8852 Offset: 1.3ppm CO2 span 1.003 -> 1.0166 Offset: -9.47ppm H2O zero 0.8262 -> 0.8292 Offset: 0.09ppm H2O span 1.0144 -> 1.0332 Offset: -0.39ppm Notes: First calibration since return from Licor. I entered all the coefficients by hand. Afterwards it was pretty right on except for CO2 span. Not sure why but decided to do the calibration.
