Summary: Power down due to failing solar system, eddy on with solar reset, but met still down

When: Date: 1/17/2005 , Day: 17 , Watch Time: 12:35pm
Where: Tonzi/Vaira Ranch
Who: Siyan
Weather: Cloudy, foggy, very wet on the grass

Summary

  1. Vaira Rain Gange SN# = 24875-9999, Model = TR-525I-R1
  2. No power for Vaira Datalogger. Maybe need bring fully charged battery to Vaira site.
  3. No power for Vaira fence.
  4. Floor and Vaira Flux systems shut down because of “LVD”. After restart the power regulator, flux systems are working.
  5. Measure soil moisture.
  6. Collect leave samples: Vaira grass, Tonzi understory grass

  1. Fence and gate power: <12.0 v.
  2. Panel and Batteries: 12.2 v; 2.4 amps; Lvd amps. After restart it, “Lvd” turned into 2.2 amps.
  3. Reading from Gillsonic screen before downloading data. (The value of H2O and CO2 should be in the range of 0 – 5 v.)
