Last calibration: 2013-08-27
AGC=88.4 SDM=1 DAC1=- DAC2=-
Ambient P=100.31kPa, Tair=24.17C, Tdew=0.47C
Zero Air at 1400psi, God CO2 421.22 at 1550 Tdewspan=15.22
CO2 zero 0.8685 -> 0.8687 Offset: 1.42ppm
CO2 span 1.0099 -> 1.0113 Offset: -0.84ppm
H2O zero 0.8539 -> 0.8531 Offset: 1.4ppm
H2O span 1 -> 0.9904 Offset: 0.49ppm
Notes: Calibrated by Joe. Initially calibrated on March 12th but had very large offsets. I discovered that very small changes in SS caused by the hood (~4%) caused about 50ppm changes in CO2. A second calibration on the 17th was much better.
