Last calibration: 2021-09-29
AGC=100 SDM= DAC1= DAC2=
Ambient P=100.6kPa, Tair=25.9C, Tdew=10.4C
Zero Air at 975psi, AMP CA04119 524.77 at 1600 Tdewspan=20.00
CO2 zero 0.9018 -> .9016 Offset: -.7ppm
CO2 span 1.0034 -> 1.0075 Offset: -2.79ppm
H2O zero 0.8689 -> .8707 Offset: 12.7ppm
H2O span 1.0112 -> 1.0158 Offset: -.1ppm
Notes: First calibration after changing the air pump diaphragm on the dewpoint generator. The H2O span looked stable after 12-15 minutes, but I waited for 30+ min to be sure.
