Title: Calibration
Notes: Last calibration: 2021-03-03 AGC=99.9 SDM=0 DAC1=- DAC2=- Ambient P=99.9kPa, Tair=20.2C, Tdew=10.9C Zero Air at 325psi, AMP CA04119 524.77 at 1800 Tdewspan=16.0 CO2 zero 0.9376 -> 0.9375 Offset: -0.4ppm CO2 span 1.0151 -> 1.0204 Offset: -3.52ppm H2O zero 0.8983 -> 0.8985 Offset: 1.3ppm H2O span 1.0319 -> 1.0268 Offset: 0.1ppm Notes: Calibrated with the wrong pressure coefficients. After fixing the pressure coefficients the H2O span was stable and rechecking the CO2 and H2O zeros were also stable - decided okay to use.
