Title: Calibration
Notes: Last calibration: 2017-08-07 AGC=105.8 SDM=0 DAC1=0 DAC2=0 Ambient P=100.2kPa, Tair=21.7C, Tdew=12.8C Zero Air at 1100psi, AMP Air 408.97 at 2000 Tdewspan=16.00 CO2 zero 0.9419 -> 0.9418 Offset: -0.45ppm CO2 span 1.0187 -> 1.0162 Offset: 1.31ppm H2O zero 0.8382 -> 0.8392 Offset: 5.9ppm H2O span 1.0141 -> 1.0214 Offset: -0.15ppm Notes: Previous calibration on 2017-08-07 did not use updated pressure coefficients from 7550 interface, so I redid the calibration.
