Title: Calibration
Notes: Last calibration: 2022-03-11 AGC=101 SDM= DAC1= DAC2= Ambient P=101.0kPa, Tair=23.6C, Tdew=8.5C Zero Air at 875psi, AMP CA04119 524.77 at 1600 Tdewspan=20.00 CO2 zero 0.905 -> .905 Offset: .15ppm CO2 span 1.0119 -> 1.0125 Offset: .25ppm H2O zero 0.8398 -> .8403 Offset: 1.9ppm H2O span 1.0137 -> 1.0196 Offset: .03ppm Notes: Third calibration after chemical swap. The sensor seems stable now. Swapping the chemicals seemed to fix the issue with the large H2O zero offsets.
