Tonzi: 2001-12-19 12:30:00 (DOY 353)
Author: Dennis Baldocchi
Others: Liukang Xu

Summary: Systems running; CR10X5 was dead due to low voltage.

WHO: Liukang Xu;
WHERE: Tonzi Ranch and Vaira Ranch
WHEN: 12/19/2001 d353
WEATHER: cloudy air temperature low 50
WHAT: check three flux systems, download data, soil moisture point sensor
reading, dendrometer reading. grass LAI sampling at Tonzi.

Around 9:20 arrive at Vaira:
The flux system was running, no communication between the computer and
CR10X. After I reboot the computer and pulled out all the cox cable
connectors and re-plugged them, the communication was established.
The lower wire of the electric fence at east side was broken, I fixed
with a another piece of wire. the battery of fence was only about 11.5 V.
The dial of the electric fence regulator was only at the middle of green
area, you can barely feel the voltage when you touch the wire. After talked
to Ted on the phone, I replaced the battery with a new one from the floor
system.

Around 12:30 arrive at Tonzi.
These cows are here ! Both flux systems were running. Nancy's CR10X5 was
dead due to the low voltage (only 5.9 V). take measurement of soil point
sensor, and dendrometer reading. and Took 6 LAI grass samples.
