I arrived about 11:00 PDT with Patty. The site continues to green up. The green is kind of patchy even within the areas of old thatch.

I worked on moving the HMP45 and air pressure sensor off the LI 7550 and on to the CR23X. The HMP45 is now on channels DIFF 5 and 6. The air pressure sensor is on SE channel 23. I changed the 7550 settings to not record the analog channels from the 7700 and removed the cable. But I did not update the 7700 settings, so this might need to be done next time.

Patty moved the incoming PAR sensor away from the camera post on the SE corner of the scaffolding to the SW corner. The new mount is kind of kludged together because we could not get the fitting off the old mount. I need to bring a new fitting next time.

The 7500 read: 406ppm CO2, 663mmol/m3 H2O, 88.8 SS

The 7700 read: 2.06ppm CH4, 8 RSSI â€“ after cleaning 2.01ppm CH4, 87 RSSI.
The wash reservoir was full. I set the wash cycle to wash every minute and nothing happened. I check all the cable connections and all looked fine. The mirror was not spinning either. Iâ€™ll look at the diagnostic values and call Licor.

I put some jumper wires in empty channels on the data logger to zero out these channels.

Patty put a new length of protective tubing on the 7700 fine wire TC.
