2. swaping Li-7500 Analyzer. (Remove SN# 65 ; install SN# 418 )
3. check the fans of air temp. and relative humidity sensors on the tower and the floor.
4. Manually calibrate Li-800. YES!

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.
