Last calibration: 2022-08-23
AGC=101.0 SDM=0 DAC1=- DAC2=-
Ambient P=100.6kPa, Tair=20.5C, Tdew=9.85C
Zero Air at 1700psi, AMP CA04119 524.77 at 1325 Tdewspan=16.00
CO2 zero 0.8678 -> 0.8678 Offset: 0.0ppm
CO2 span 1.0008 -> 1.0144 Offset: -9.57ppm
H2O zero 0.8537 -> 0.8553 Offset: 9.8ppm
H2O span 0.923 -> 0.9281 Offset: -0.12ppm
Notes: Large offset in CO2 span. But this largely undoes some similar previous increases. Calibrated at the same time sn 2180 showed a similar CO2 span offset. This calibration was using 7550 box 0674 instead of the AMP loaner but I don't see how that should effect only CO2 span. Going to go with it.
