| LI-7500A 0073 | 2017-06-22 | Lab none | Calibration | Lab none | Last calibration: 2017-06-21 AGC=100.4 SDM= DAC1= DAC2= Ambient P=99.8kPa, Tair=25.8C, Tdew=14.5C Zero Air at 1450psi, NOAA Air 402.69 at 1600 Tdewspan=16.00 CO2 zero 0.9574 -> .9572 Offset: -1.08ppm CO2 span 1.0075 -> 1.0084 Offset: -.35ppm H2O zero 0.7305 -> .7307 Offset: 1.2ppm H2O span 1.0071 -> 1.0045 Offset: -.06ppm Notes: Matches well with calibration from previous day. |
| LI-7500A 0073 | 2017-06-21 | Lab none | Calibration | Lab none | Last calibration: 2017-06-13 AGC=101.1 SDM= DAC1= DAC2= Ambient P=99.3kPa, Tair=24.2C, Tdew=12.7C Zero Air at 1450psi, NOAA Air 402.69 at 1600 Tdewspan=16.00 CO2 zero 0.9567 -> .9574 Offset: 2.42ppm CO2 span 1.0065 -> 1.0075 Offset: -.67ppm H2O zero 0.7342 -> .7305 Offset: -21.8ppm H2O span 1.0251 -> 1.0071 Offset: .4ppm Notes: Checking the zero and spans after upgrade from 7500 to 7500A. There are jumps in CO2 zero and span so I will check again tomorrow. |
| LI-7500A 0418 | 2017-06-21 | Lab none | Calibration | Lab none | Last calibration: 2017-06-20 AGC=96.8 SDM= DAC1= DAC2= Ambient P=99.4kPa, Tair=24.7C, Tdew=12.2C Zero Air at 1450psi, NOAA Air 402.69 at 1600 Tdewspan=16.00 CO2 zero 0.8994 -> .8992 Offset: -.84ppm CO2 span 0.9961 -> .9985 Offset: -1.31ppm H2O zero 0.8423 -> .8432 Offset: 4.9ppm H2O span 0.9658 -> .9806 Offset: -0.33ppm Notes: Re-testing zero and spans after large change in H2O zero/span and a smaller change in CO2 zero after upgrade from 7500 to 7500A. The coefficients seem stable now. The changes in H2O and CO2 zeros after upgrade might be from changing out the old chemicals for fresh chemicals during the upgrade. |

H2O zero is pretty stable, but there was a relatively large shift in H2O span. I'll re-test tomorrow. |
