Last calibration Nov 16, 2010
AGC=67, SDM=7, DAC1 0-1000 H2O, DAC2 10-25 CO2
P=101.84 kPa Tair=21.06C, Tdew=~-1C
Zero air no scrub 1600psi, CO2 597.4ppm 150psi, Tdew=-7.1C
Precal CO2 zero=0.9622, span=0.9827
Postcal CO2 zero=0.9605, span=0.9855
Precal H2O zero=0.7829, span=0.9693
Postcal H2O zero=0.7877, span=1.1467
CO2 zero off by -6.13ppm, span off by -2.3ppm
H2O zero off by +30.7mmol/m3, span off by -2.4C
The weather is warm and dry making the dew point very low and difficult to calibrate. |
