Vaira
16:01 sunny clear conditions
solar amp = 1.7
batt volt = 11.9
load = lvd

16:11
open solar panel connection boxes and almost all contacts are loose.

Discover burned wire on second solar panel. This is the problem with the depleted battery capacity. Repair and all seems well.

Batt volt = 13.3
Solar amp = 26.4
Load amp = 3.1

Batter status LED = green: full charge

16:37 asperator fan barely running. Disconnect fan and measure voltage = 12.2. Connect fan and voltage falls to 5.0 volts. Discover bad connection on splice and repair. I suspect this bad connection was drawing power and caused the data logger battery to fail.

Floor
Sunday
10:22 Reestablish communications with all loggers. Problem was a bad connection in the connector to the base MD9. Traveled to Radishack, obtained a suitable adapter and repaired unit

10:30 Floor system
Batt volts = 12.6
Solar Amp = 6.5
Load amp = 3.5

This does not compare well with Vaira.
15:27
Batt Volt = 13.0
Solar Amp = 8.3
Load amp = 2.4
Batt status LED Green


Monday
Vaira 10:35
NDVI cable on boom arm pulling instrument out of alignment. Correct the situation and level the unit.

10:54 NDVI sensor leveled.
