Summary: Predawn water potential, fix z-cam 1 wire, fixed CO2 profile, did not fix tram and floor hmp45 fan, condensation in diffuse sensor.

2014-04-22

I arrived at about 5:45am PDT with Siyan for predawn water potential. The day was cool and partly cloudy with a breeze from the south west. The grass looks good and the tree seemed to be done putting on leaves. The ground is still damp in low areas, but Tonziâ€™s pond is only about half full.

I worked on running a new wire for z-cam 1 to the south of the tower. The new wire is run in the air from the tower through the trees. It has three conductors: one 12VDC power for the camera, a switched 12VDC for the power button relay, and they both share the same ground. It seemed to work well. I reset the clock on the z-cam CR10X, it was about 5 minutes behind. I serviced all the zcams.

The tram was not moving near mid-track. I reset it and it ran to park just fine. Later I found it stuck mid track again. I brought it in thinking the battery was bad, but the battery tested okay in the lab.

I cleaned the radiation sensors on the tower top. The diffuse sensor had a lot of condensation inside its dome. It has an internal desiccant pack that should be replaced, but I need the manual to figure out how and a replacement pack.

The fan for the floor HMP45 was dead. I removed the fan, need a new one for next time.

The CO2 profile on the tower was reading negative and could not be calibrated. I took it apart and found what looked like a water stain in the cell. I was able to clean it in the field and it calibrated well.

We went to Vaira about 9am and returned about 10:30.
