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 psig; flow psi.
N₂ psig; flow psi.
Manually calibrate Li-800. Following Ted’s instruction: H:\IoneSavanna_2004\Tower_2004\CO2Profile\LI800_Calibration_Procedure_2Nov04.txt
Is the pump running‌ No running
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.

1. close gate and set up fence. YES!
