Last calibration: 2016-08-15
AGC=57 SDM=7 DAC1=0-1000 DAC2=10-25
Ambient P=99.9kPa, Tair=21.3C, Tdew=12.16C
Zero Air at 1600psi, NOAA CO2 513.22 at 400 Tdewspan=16.01
CO2 zero 0.8594 -> 0.8594 Offset: -0.01ppm
CO2 span 1.0083 -> 1.0097 Offset: -1.12ppm
H2O zero 0.6317 -> 0.6348 Offset: 21.6ppm
H2O span 1.0114 -> 0.9689 Offset: 0.95ppm
Notes: Notes from last time said that the hood thermistor was not used and that there was a large change in H2O zero. I used hood thermistor this time and large offsets in H2O zero and span. Set span temperature to 15.94 in software for the spanned temperature to match the dewpoint generator at 16.01.
