Calibration |
| Notes: |
Last calibration: 2012-05-17
AGC=53 SDM=7 DAC1=0-1000 DAC2=10-25
Ambient P=100.49kPa, Tair=21.28C, Tdew=11.87C
Zero Air at 1900psi, CO2 in air 436.53 at 1400 Tdewspan=15.08
CO2 zero 0.9546 -> 0.9513 Offset: -12.72ppm
CO2 span 1.0182 -> 1.0044 Offset: 7.97ppm
H2O zero 0.8346 -> 0.8472 Offset: 72.5ppm
H2O span 0.8284 -> 0.9696 Offset: -3.2ppm
Notes: Relatively large offsets seem to counter similar large offsets seen at last calibration. H2O zero offset may be a typo.
