| Notes: |
Last calibration: 2020-08-20
AGC=99.3 SDM=0 DAC1=- DAC2=-
Ambient P=100.3kPa, Tair=28.4C, Tdew=11.0C
Zero Air at 0psi, AMP CA04396 408.97 at 0 Tdewspan=20.0
CO2 zero 0.8651 -> 0.8646 Offset: -2.1ppm
CO2 span 1.02124 -> 1.0131 Offset: -0.32ppm
H2O zero 0.8838 -> 0.8890 Offset: 29.85ppm
H2O span 1.015 -> 1.000 Offset: 0.35ppm
Notes: The usual 7550 box in the lab is running the newest firmware v8.8 and is complaining that the v8.5 config file has bad number formats for GPS locations. I used 7550 sn AIU-1866 for calibration instead. This box and head will go to replace equipment on the BC tower that fell in the water.
