Title: Calibration
Notes: Last calibration: 2019-11-12 AGC=100.5 SDM= DAC1= DAC2= Ambient P=100.1kPa, Tair=20.3C, Tdew=10.11C Zero Air at 850psi, AMP CA4396 408.97 at 550 Tdewspan=20.00 CO2 zero 0.9481 -> .9490 Offset: 3.19ppm CO2 span 1.0091 -> 1.0182 Offset: -4.69ppm H2O zero 0.8449 -> .8441 Offset: -4.7ppm H2O span 1.0139 -> 1.0341 Offset: -.45ppm Notes: This sensor was on the BC tower when it fell down because of a wind/rain storm on 2019-11-26. First calibration since it was brought back to the lab. The CO2 span is larger than I expected. More testing needed before putting it back up in the field.
