Title: Calibration
Notes: Last calibration: 2022-08-30 AGC=101.0 SDM=0 DAC1=- DAC2=- Ambient P=100.6kPa, Tair=21.3C, Tdew=9.2C Zero Air at 1700psi, AMP CA04119 524.77 at 1300 Tdewspan=16.0 CO2 zero 0.9148 -> 0.9145 Offset: -1.53ppm CO2 span 1.0318 -> 1.0433 Offset: -7.27ppm H2O zero 0.8916 -> 0.8933 Offset: 10.7ppm H2O span 1.0122 -> 1.0381 Offset: -0.53ppm Notes: Large offset in CO2 span but also large offset when removed from tower and similar offset in sn 2176 CO2 span calibrated at the same time. Used our 7550 box 0674 instead on the AMP loaner used previously. I think this IRGA is okay.
