Title: Calibration
Notes: Last calibration: 2019-04-15 AGC=87.5 SDM= DAC1= DAC2= Ambient P=100.6kPa, Tair=23.9C, Tdew=13.6C Zero Air at 975psi, AMP CA4396 408.97 at 800 Tdewspan=20.00 CO2 zero 0.8842 -> .8846 Offset: 1.90ppm CO2 span 1.0156 -> 1.0226 Offset: 3.54ppm H2O zero 0.8459 -> .8456 Offset: -1.6ppm H2O span 1.0189 -> 1.0214 Offset: -.05ppm Notes: When SS was 87.5, 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.
