Title: Calibration
Notes: Last calibration: 2021-08-31 AGC=100.7 SDM= DAC1= DAC2= Ambient P=100.4kPa, Tair=25.6C, Tdew=6.06C Zero Air at 100psi, AMP CA04119 524.77 at 1700 Tdewspan=20.00 CO2 zero 0.9188 -> .9186 Offset: -.81ppm CO2 span 1.0127 -> 1.0133 Offset: -.02ppm H2O zero 0.9005 -> .9008 Offset: 2.1ppm H2O span 1.0086 -> 1.0123 Offset: -.09ppm Notes: Not much air left in the zero air tank, but the zero was stable for 2+ min after setting the zeros, so I feel comfortable the calibration was good. Initially forgot to save the new config, so re-opened the prev file from 2021-08-31, entered the 4 coefficients manually, and saved with today's date.
