Calibration |
| Notes: |
Last calibration: 2015-07-22
AGC=102.5 SDM=1 DAC1=- DAC2=-
Ambient P=102.5kPa, Tair=20.08C, Tdew=14.29C
Zero Air at 500psi, God CO2 421.22 at 450 Tdewspan=16.00
CO2 zero 0.9197 -> 0.9190 Offset: -2.83ppm
CO2 span 1.0015 -> 1.0141 Offset: -6.87ppm
H2O zero 0.8907 -> 0.9987 Offset: 27.8ppm
H2O span 0.9987 -> 1.0143 Offset: -0.33ppm
Notes: First time this sensor has been calibrated in the lab. Last cal was by Licor using 749.7ppm CO2 and 11.98C dew point. Offsets a little high especially H2O zero. Difference in calibration equipment and procedures?
