Trip Purpose Install LI7500 on tower and restart the flux platform

Tonzi Ranch:
Saturday 15:00 arrive and begin installation of LI7500. While installing the bird spikes the top of the egg on the LI7500 was dropped and either the o-ring fell out or it was not there in the first place. I assembled the unit and used electrical tape to seal the egg.

Perform zero/span twice on tower co2 profile system.

Sunday 10:00 all appears well. I do notice that the Temp. CO2 & H2O signals look noisy as compared with the Floor and Vaira systems

Communication established with all data loggers.

Unable to determine why soil moisture (50cm) not functioning.
