Title: Calibration
Notes: Last calibration: 2019-04-26 AGC=99.2 SDM= DAC1= DAC2= Ambient P=100.6kPa, Tair=24.0C, Tdew=13.8C Zero Air at 975psi, AMP CA4396 408.97 at 800 Tdewspan=20.00 CO2 zero 0.9371 -> .9374 Offset: 1.23ppm CO2 span 1.0189 -> 1.0207 Offset: -.96ppm H2O zero 0.8989 -> .8984 Offset: -2.9ppm H2O span 1.0186 -> 1.0323 Offset: -.29ppm Notes: When the SS was 99.2, 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.
