Title: Calibration
Notes: Last calibration: 2018-02-05 AGC=101.2 SDM=0 DAC1=0 DAC2=0 Ambient P=101.2kPa, Tair=23.3C, Tdew=4.2C Zero Air at 100psi, LBL Air 408.97 at 1700 Tdewspan=16.00 CO2 zero 0.8674 -> .8679 Offset: 2.12ppm CO2 span 1.0032 -> 1.0057 Offset: -1.52ppm H2O zero 0.851 -> .8486 Offset: -15.8ppm H2O span 1.0142 -> .9112 Offset: 2.31ppm Notes: First calib in the lab since Licor factory repair/calib. The H2O zero and span have large offsets because the Licor factory H2O calibration station failed. Our dewpoint generator results matched with Patty's dewpoint generator.
