| Notes: |
Last calibration: 2024-01-02
AGC=100.7 SDM= DAC1= DAC2=
AIU sn AIU-1866, Presure A0=58.31, A1=15.48
Ambient P=100.96kPa, Tair=22.82C, Tdew=9.50C
Zero Air at 300psi, AMP CA04119 524.77 at 550 Tdewspan=20.00
CO2 zero 0.9372 -> .9377 Offset: -.4ppm
CO2 span 1.0267 -> 1.0226 Offset: .98ppm
H2O zero 0.9006 -> .8987 Offset: -11.1ppm
H2O span 1.04 -> 1.0279 Offset: -.16ppm
Notes: H2O zero was drifting up after stabilizing, but CO2 zero ok. Maybe we need to change the internal chemicals next time? I redid the H2O zero point after finishing the rest of the calibration. The offset changed from 0.8969 to 0.8987 (tiny change). Used 524.65 as span point in the software for post-span CO2 value to be around 524.77.
