Reinstalled after having been returned to the lab when it would not start due to being hot. (Note by Daphne 2021-08-11: I'm pretty sure this chamber was installed under the tower since we were waiting for our field to be harvested at this time). |

Lab none |
This unit was non-responsive in the field. In the lab it started right up and I was able to collect and clear its data. These units have had an issue with not starting up when they are too hot though this is supposed to be fixed in newer units. Maybe this unit has the too-hot-to-start problem and this combined with the power outage observed at Bouldin Corn to knock it out. Maybe I'll ask Camilo to put it back on Monday. |
