Title: Calibration
Notes: Last calibration: 2022-08-25 AGC=99.4 SDM= DAC1= DAC2= Ambient P=100.4kPa, Tair=18.8C, Tdew=11.5C Zero Air at 1625psi, AMP CA04119 524.77 at 1275 Tdewspan=16.00 CO2 zero 0.9374 -> .9374 Offset: .2ppm CO2 span 1.0234 -> 1.0295 Offset: -3.97ppm H2O zero 0.8995 -> .9003 Offset: 4.9ppm H2O span 1.0334 -> 1.0369 Offset: -.06ppm Notes: Setting the CO2 span to 524.77ppm seemed to force the value to ~524.85 instead of 524.77. I think it's ok for now but something to keep an eye on. H2O value was not stabilizing when dewpt generator was set to 20.00C, probably because the room's dewpt<20.00C. I set the span point to 16.00C instead, which worked well.
