AGC=100.4 SDM= DAC1= DAC2=
Ambient P=100.5kPa, Tair=20.6C, Tdew=13.4C
Zero Air at 1875psi, AMP CA04119 524.77 at 1350 Tdewspan=20.00
CO2 zero 0.9412 -> .9413 Offset: .3ppm
CO2 span 1.0171 -> 1.0204 Offset: -2.27ppm
H2O zero 0.841 -> .8407 Offset: -1.7ppm
H2O span 1.018 -> 1.0338 Offset: .01ppm
Notes: Calibrated with AMP 7550 sn AIU-1039. At first, large H2O span offset (-0.32) than usual. The condenser water tube in the back was low on water. I opened the cap to let water level rise again. Afterwards, H2O span was right on (offset 0.01).
