Notes: Last calibration: 2022-11-28 AGC=99 SDM= DAC1= DAC2= Ambient P=101.5kPa, Tair=23.4C, Tdew=2.53C Zero Air at 1450psi, AMP CA04119 524.77 at 1250 Tdewspan=16.00 CO2 zero 0.8643 -> .8656 Offset: 5.31ppm CO2 span 1.0168 -> 1.0205 Offset: -2.43ppm H2O zero 0.8889 -> .8869 Offset: -10.6ppm H2O span 1.0136 -> 1.0127 Offset: .02ppm Notes: This sensor was not working at BC, but it worked in the lab and the calibration seems within normal range. I'll run it for a few days in the lab to see if it's stable.
