Calibration |
| Notes: |
Last calibration: 2019-08-01
AGC=101.0 SDM=0 DAC1=- DAC2=-
Ambient P=100.8kPa, Tair=26.9C, Tdew=-1.45C
Zero Air at 800psi, AMP CA04396 408.97 at 550 Tdewspan=16.0
CO2 zero 0.9022 -> 0.9030 Offset: 3.7ppm
CO2 span 1.0086 -> 1.0154 Offset: -3.47ppm
H2O zero 0.8673 -> 0.8674 Offset: 0.5ppm
H2O span 1.0114 -> 1.0224 Offset: -0.23ppm
Notes: First calibration after swapping chemicals and running on the bench for a week. I was expecting to see negative offsets from zero - may still drift a little lower. Ambient air very dry.
