Last calibration: 2016-12-23
AGC=100.5 SDM= DAC1= DAC2=
Ambient P=101.1kPa, Tair=23.6C, Tdew=7.63C
Zero Air at 1600psi, NOAA CO2 513.22 at 250 Tdewspan=16.00
CO2 zero 0.9145 -> 0.9144 Offset: -0.53ppm
CO2 span 1.0287 -> 1.026 Offset: 1.83ppm
H2O zero 0.8836 -> 0.8861 Offset: -1.4ppm
H2O span 1.0124 -> 1.023 Offset: 0.5ppm
Notes: I re-did the H2O zero because the first offset was large, so I wanted to double check. The first offset was 16.8 mmol/m3. The second offset was -1.4 mmol/m3, so I felt confident in the calibration.
