Title: Calibration
Notes: Last calibration: 2021-10-16 AGC=99.7 SDM=0 DAC1=- DAC2=- Ambient P=100.96kPa, Tair=25.3C, Tdew=10.6C Zero Air at 1400psi, AMP CA04119 524.77 at 1700 Tdewspan=20.0 CO2 zero 0.9182 -> 0.9175 Offset: -2.7ppm CO2 span 1 -> 1.0 Offset: -0.47ppm H2O zero 0.8187 -> 0.8174 Offset: -7ppm H2O span 1.0094 -> 1.0192 Offset: 0.22ppm Notes: This is the first lab calibration since refurbishment and factory calibration at Licor. I entered the new coefficients by hand. The dew point generator was acting funky again. I added water and it seemed better. The offsets were relatively good for a unit freshly returned from the factory.
