|---|---|---|---|---|---|
| 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. |
