Calibration |
| Notes: |
Last calibration: 2022-01-11
AGC=100 SDM= DAC1= DAC2=
Ambient P=99.99kPa, Tair=23.1C, Tdew=9.47C
Zero Air at 925psi, AMP CA04119 524.77 at 1600 Tdewspan=20.00
CO2 zero 0.9049 -> .9044 Offset: -2.15ppm
CO2 span 1.0047 -> 1.0101 Offset: -3.55ppm
H2O zero 0.8391 -> .8433 Offset: 30.2ppm
H2O span 1.0087 -> 1.0199 Offset: -.25ppm
Notes: Large positive H2O zero. Not really sure why it's difficult to get a good calibration. Is the sensor changing that much between calibrations (even though it's just been sitting in the lab)? Or is there something inconsistent about my calibration method?
