Title: Calibration
Notes: Last calibration: 2019-04-15 AGC=97.7 SDM= DAC1= DAC2= Ambient P=100.7kPa, Tair=23.4C, Tdew=13.3C Zero Air at 975psi, AMP CA4396 408.97 at 800 Tdewspan=20.00 CO2 zero 0.9014 -> .9022 Offset: 3.41ppm CO2 span 1.003 -> 1.0086 Offset: -2.05ppm H2O zero 0.8671 -> .8673 Offset: 1.2ppm H2O span 1.0077 -> 10.114 Offset: -.08ppm Notes: When SS was 97.7, I reset it to 100. I uploaded the the calibration file from 2018-10-24 and copied in the manual coefficients for CO2 span, CO2 zero, H2O span, and H2O zero from the database's record of the most recent calibration on 2019-04-15.
