Last calibration: 2017-05-30
AGC=97.2 SDM=0 DAC1=0 DAC2=0
Ambient P=100.1kPa, Tair=29.4C, Tdew=12.3C
Zero Air at 590psi, AMP Air 408.97 at 2100 Tdewspan=16.00
CO2 zero 0.8653 -> .8638 Offset: -6.17ppm
CO2 span 1.0187 -> 1.0168 Offset: 1.13ppm
H2O zero 0.8861 -> .8878 Offset: 9.5ppm
H2O span 1.0256 -> 1.0047 Offset: .44ppm
Notes: When I checked ffsets after this calibration, CO2 zero offset=-0.64 ppm, H2O zero offset=1.2 mmol/m3, and CO2 span offset=0.21 ppm. Calibrated on LI-7550 with embedded software version 8.7.5.
