Calibration |
| Notes: |
Last calibration: 2011-02-02
AGC=68 SDM=7 DAC1=0-1000 DAC2=10-25
Ambient P=100.3kPa Tair=21.98C, Tdew=11.9C
zero air at 1450psi, co2 in air 597.4ppm 100psi Tdewspan=16.9
CO2 zero 0.9605 -> 0.9587 Offset: -8.14ppm
CO2 span 0.9855 -> 0.9796 Offset: 11.6ppm
H2O zero 0.7877 -> 0.7886 Offset: -2.9mmol/m3
H2O span 1.1467 -> 0.9667 Offset: 4.62C
Notes: I initiall tried to calibrate on 6/14 but was rushed and got some odd behavior so did a better calibration on 6/15. The offsets are estimates based on the two calibrations.
