Notes: Last calibration: 2020-05-22 AGC=99.5 SDM= DAC1= DAC2= Ambient P=100.8kPa, Tair=24.8C, Tdew=7.7C Zero Air at 525psi, AMP CA4396 408.97 at 375 Tdewspan=20.00 CO2 zero 0.8849 -> .8850 Offset: .26ppm CO2 span 1.0267 -> 1.0259 Offset: .41ppm H2O zero 0.8471 -> .8473 Offset: 1.7ppm H2O span 1.0159 -> 1.0212 Offset: -.12ppm Notes: H2O span was taking a while, so I turned off the LI-610 and added in 20ml DI water to the reservoir. I restarted the H2O span and after waiting a while, it looked stable in the end.
