Calibration |
| Notes: |
Last calibration: 2021-03-15
AGC=99.0 SDM=0 DAC1=- DAC2=-
Ambient P=100.4kPa, Tair=22.0C, Tdew=10.9C
Zero Air at 300psi, AMP CA04119 524.77 at 1800 Tdewspan=16.0
CO2 zero 0.957 -> 0.9568 Offset: -0.6ppm
CO2 span 1.0077 -> 1.0071 Offset: 0.43ppm
H2O zero 0.7324 -> 0.7324 Offset: 2.2ppm
H2O span 1.0024 -> 1.0037 Offset: -0.03ppm
Notes: I started to calibrate this IRGA and I thought the signals looked noisy. At first I thought it might be a problem the the zero air flow rate and upped that a bit but no change. Then I calibrated sn 0418 and it seemed normal. I did a full calibration and while the numbers are pretty much right on all CO2, H2O zero and span were more noisy than usual. Don't deploy this one until some further checking is done.
