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