Calibration |
| Notes: |
Last calibration: 2019-07-24
AGC=99.5 SDM= DAC1= DAC2=
Ambient P=100.5kPa, Tair=25.6C, Tdew=11.4C
Zero Air at 900psi, AMP CA4396 408.97 at 650 Tdewspan=16.00
CO2 zero 0.8672 -> .8675 Offset: 1.36ppm
CO2 span 1.0061 -> 1.0072 Offset: -.67ppm
H2O zero 0.8521 -> .8520 Offset: -1.0ppm
H2O span 0.9182 -> .9123 Offset: .13ppm
Notes: Did an initial calibration yesterday using config file 2019-07-24, but it had a large H2O zero offset (-35.7 mmol/m3) and H2O span offset (1.53C). Today I did another calibration, again from the config file 2019-07-24. Today the H2O offset/span seem ok, so not sure what was happening yesterday. I saved today's new config file and deleted yesterday's to avoid confusion.
