Title: Calibration
Notes: Last calibration: 2017-01-30 AGC=99.6 SDM= DAC1= DAC2= Ambient P=100.6kPa, Tair=28.2C, Tdew=12.8C Zero Air at 1700psi, God Air 421.22 at 400 Tdewspan=16.00 CO2 zero 0.9392 -> 0.9392 Offset: 0.11ppm CO2 span 1.012 -> 1.0131 Offset: 0.57ppm H2O zero 0.9039 -> 0.9041 Offset: 1.0ppm H2O span 1.0054 -> 1.0063 Offset: .01ppm Notes: This sensor has been upgraded to firmware version 8.5.0. I connected it to Licor box sn AIU-0674 and used software version 8.5.0 to calibrate this sensor in order to calibrate the temperature coefficients (these coefficients are not calibrated in software version 8.0.0).
