Title: Calibration
Notes: Last calibration: 2019-04-15 AGC=102.6 SDM= DAC1= DAC2= Ambient P=100.7kPa, Tair=22.7C, Tdew=14.1C Zero Air at 975psi, AMP CA4396 408.97 at 800 Tdewspan=20.00 CO2 zero 0.9186 -> .9178 Offset: -3.12ppm CO2 span 1.0134 -> 1.0125 Offset: .53ppm H2O zero 0.8991 -> .9019 Offset: 17.8ppm H2O span 1.0017 -> 1.015 Offset: -.3ppm Notes: When SS was 102.6, 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.
