Kurt and I went to the bao site to fix the EC150. Swapping cables, reseating the terminal block connectors, and swapping EC100 electronics boxes didn't help. Changing from a titan to an emerald port did. This sensor is now on port 8 (this required Kurt to change the jumper on this port). Gordon made the config changes from Boulder. A detail: we also added a screen to the (new) EC100 temperature inlet.
In the process of lowering and raising the mast, the mast height shifted. We moved it back, but it now is 1-2cm higher than before. Also, the boom angle may have changed. I took two photos to try to document the new boom angle, and I'll update this entry later with these values.
I estimate that the mast was down from 1030-1110, then we messed with the mast height until 1130.
Conditions were snow flurries, T ~ -4C, wind 4 m/s. Not great for this type of work!
