Last calibration: 2017-06-12
AGC=57 SDM=7 DAC1= DAC2=
Ambient P=100.7kPa, Tair=25.8C, Tdew=15.3C
Zero Air at 300psi, AMP CA04119 524.77 at 1425 Tdewspan=20.00
CO2 zero 0.8597 -> .8596 Offset: -.03ppm
CO2 span 1.0077 -> 1.0102 Offset: 1.82ppm
H2O zero 0.6335 -> .632 Offset: -10.5ppm
H2O span 1.031 -> 1.0138 Offset: .37ppm
Notes: Pulled out this old IRGA for Robert's UHI transect via ebike. The calibration was surprisingly good given we haven't used this sensor in 5 years. Calibrated using a small white eePC netbook using a Licor serial cable that plugs directly into the green terminal block inside the box. I had to set the span temperature in software to 19.91 in order for dew point value to be 20.00 after pressing "Span".
