H2O and CO2 channel looked spiky, need to be swapped next time.

1. downloading data YES!
2. check the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
3. Check calibration cylinders;

CO₂ 500 psig; flow 20 psi.
N₂ 1650 psig; flow 20 psi.
Manually calibrate Li-800. Following Ted’s instruction: YES!
