Sherman
2012-02-15

I arrived about 9:00PST. It was clear, sunny, and super windy. Wind speed was about 12m/s. The field looks greener and there were some sprouting leaves on the pepper weed inside the cow fence. The cows continue to be fed directly upwind from the tower. The ditch along the road was still low in water. I drove into the field in a small car.

I swapped the charge controller that was regulating the 12VDC supply. I removed a Morningstar and swapped in a Kintrex. The morning star could do 24V and I needed that at Varia. This swap brought down the power for a few minutes.

I installed a LI-7700 sn TG1-0223 and NL115 sn 6761. No problems on install. After swapping the card, I changed the CR1000 program to add the LI-7700 channels.

I collected data. The sensors looked clean.
