Last calibration: 2017-11-28
AGC=100.3 SDM=0 DAC1=0 DAC2=0
Ambient P=100.9kPa, Tair=21.7C, Tdew=8.5C
Zero Air at 100psi, LBL Air 408.97 at 1700 Tdewspan=16.00
CO2 zero 0.9392 -> .9393 Offset: .46ppm
CO2 span 1.0147 -> 1.0147 Offset: -.1ppm
H2O zero 0.9066 -> .9038 Offset: -15.5ppm
H2O span 1.0125 -> 1.0146 Offset: -.04ppm
Notes: Calibrated on LI-7550 sn 674 with 8.5.0 embedded software version. Large H2O offset but last calibration, the offset was +11 mmol/m3 (similar magnitude and opposite sign), so I think it's ok, maybe something wonky last calibration.
