1. downloading data YES!
2. check the fans of air temp. and relative humidity sensors on the tower and the floor. YES!
3. Check rain gage, make sure not clogged. YES!
4. Check calibration cylinders;

CO₂ 1000 psig; flow 20 psi.
N₂ 2000 psig; flow 20 psi.
Manually calibrate Li-800. Following Ted’s instruction: H:\IoneSavanna_2004\Tower_2004\CO2Profile\LI800_Calibration_Procedure_2Nov04.txt
Is the pump running‌ YES!
How to check the CO2 values‌ Click “Ports/Flags” button to see which ports or flags is setting high. Pressure should be less than ambient value. When Flag 8 is high, it may indicate that RRR’s battery is low. YES!
