PC time was about one second difference from GPS. No correction was taken.
check the fans of air temp. and relative humidity sensors on the tower and the floor.
Check calibration cylinders;

CO₂ 1000 psig; flow 18 psi.
N₂ 1300 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 OK

close gate and set up fence. OK
