Vaira_Grass
Site
- Fence and gate power: 12 v.
- Panel and Batteries: 13.5 v; 0.0 amps; OFF amps.
NO POWER! NO RUNNING!
- Check levels of Radiation
sensors, clear up surfaces. YES!
- Check rain gage, make sure
not clogged. YES!
- Closed gate and set up fence.
YES!
Tonzi_Tower Site
- Fence and gate power: 12 v.
- Panel and Batteries: 12.7
v; 0.0
amps; 3.7
amps.
- Reading from Gillsonic screen
before downloading data. (The
value of H2O and CO2 should be in the range of 0 – 5
v.)
- downloading data NO!
- check the fans of air temp.
and relative humidity sensors on the tower and the floor. NO!
- Check rain gage, make sure not
clogged. YES!
- Check calibration cylinders;
CO 2 700 psig; flow 30 psi; 418.8
ppm.
N 2 300
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 Pump wasn’t
working. Click it and it worked.

- close gate and set up fence. YES!
Toniz_Floor
Site
- Fence and gate power: 12 v.
- Panel and Batteries: 12.3 v; 1.5
amps; 1.9
amps. (about
7:00 am local time)
- Reading from Gillsonic screen
before downloading data. (The
value of H2O and CO2 should be in the range of 0 – 5
v.)
LOOKS
OK, BUT THE POWER DIDN’T ALLOW ME TO SAVE “PRINT SCREEN” .
- downloading data NO!
- Check MD-9 system
connections NO!
- Soil CO2 profile:
no power when I got there. I
unplug and re-plug fuses, then the system back to work.
