|---|---|---|---|---|---|
| LI-7500A 75H-2514 | 2023-12-05 | Factory none | Received | Lab none | Received back from Licor after chopper motor replacement and recalibration |
| LI-7810 TG10-01751 | 2023-12-01 | Lab none | Calibration | Lab none | Last calibration: 2023-08-22 Zero Air at ???psi, AMP CA04119 4223.8 ppb CH4 at ???psi CO2 zero Offset: -0.024ppm H2O zero Offset: -10.52ppm CH4 zero Offset: 0.129ppb CH4 span Offset: -1ppb Notes: Calibration in the lab before Kuno's field campaign next week. Ran zero and span gases at our usual flow rate of 2 SCFH and plumbed the system with the recommended 30cm vent before the air inlet to vent excess air pressure and to prevent diffusion of ambient air into the gas stream. I waited until the slope of H2O was <0.002ppm to set the zero. I waited until the slope of CH4 was <0.002ppb to set the span. Plan 45min+ for H2O zero to stabilize. I forgot to write down the exact CH4 span offset, but I saved a screenshot and estimated the offset based on the graph. |
| LI-7550 AIU-1866 | 2023-12-01 | Factory none | Received | Lab none | Received back from Licor. This 7550 sn AIU-1866 went back to Licor for a power problem. Licor replaced the 7550 main power supply under warranty, subjected the units to environmental tests and verified the operation of the units. It was shipped with 7500A sn 75H-2669 (nothing wrong with the 7500A, it was just the sensor attached when the box died) |
| LI-7500A 75H-2669 | 2023-12-01 | Factory none | Received | Lab none | Received back from Licor. It was shipped with LI-7550 sn AIU-1866 which went back to Licor for (another) power board repair. There was nothing wrong with this 7500A sn 75H-2669, but Israel requested we send it back as well b/c it was connected when the LI-7550 broke. Licor replaced the 7550 power supply, subjected the units to environmental tests and verified the operation of the units. |
| eosFD FD20180048 | 2023-11-13 | Tonzi-SoilCO2 Forced Diffusion Open | Removed | Lab none | Removed because CO2 readings seem to be too low. We tried a performance check but missed being able to reset the offset. Brought to the lab for testing. The fluxes were zero. |
| BB-Fab BB-TF | 2023-11-13 | Tonzi Battery Bank Floor | Upgrade | Tonzi Battery Bank Floor | We removed four flooded batteries that came from the Tower. Two are probably still good. The other two seemed to be internally shorted. Four new group 27 AGM batteries were installed. |

| CR10X 3501 | 2023-11-14 | Lab none | Maintenance | Lab none | Put in a new internal lithium battery and testing in the lab. May use this datalogger for the PAR/RNET sensors on the BWW roof because I was having trouble connecting to the Goldstein lab CR10X. |
| CR10X 13214 | 2023-11-14 | Lab none | Tested | Lab none | Sticker on datalogger says it has a new internal battery as of November 2022. I was able to connect but the connection kept flickering. |

| BB-Fab BB-WP | 2023-09-19 | West Pond Battery Bank | Maintenance | West Pond Battery Bank | I disconnected the batteries and tested them with the load tester. The first three from the west tested okay but the last one on the east tested weak. These are wired in 24V pairs and the one paired with the weak battery had a bunch of corrosion on its positive terminal. So I disconnected these two and left the system running on a single pair. I also check the water levels and added a little water to a couple of cells that were low. |

| CTD-10 1782503941 | 2023-09-12 | Hill Slough Water Level | Removed | Lab none | Removed from the HS channel because it was shorting out the other sensors connected to the CR23x (EXO, eosGP). Unfortunately METER no longer services the CTD-10, so we will need to replace it with a new HYDROS21. |
| Mark II C011018 | 2023-09-12 | Bouldin Alfalfa Weather Station PL_S-B | Removed | Lab none | Removed with post and ground anchor since the PL-Arable project is currently paused according to PL. This unit had one red status light (bad sensors?) when I shut it down. |
| Mark II C011081 | 2023-09-12 | Bouldin Corn Weather Station PL_B | Removed | Lab none | Removed with post and ground anchor for a location near the road to the southeast of the tower. The PL-Arable project is paused according to PL. All for status lights were green when I shut it down. |
| BB-Fab BB-WP | 2023-01-18 | West Pond Battery Bank | Tested | West Pond Battery Bank | The batteries looked clean and in good condition. After disconnecting and isolating them, two of the six tested bad: 4 and 5 counting from the west. The system is wired in pairs for 24V and the two bad batteries were members of adjacent pairs. They were also the only ones that had cells that were low on water. Joe removed the two bad batteries then reconnected the remaining four. |

Zero Air at 900psi, AMP CA04119 4223.8 ppb CH4 at 850psi CO2 zero Offset: -20.9ppm H2O zero Offset: -93.5ppm CH4 zero Offset: 0.1ppb CH4 span Offset: 33.7ppb Notes: First calibration in the lab for sn TG10-01751. Ran zero and span gases at our usual flow rate of 2 SCFH and plumbed the system with the recommended 30cm vent before the air inlet to vent excess air pressure and to prevent diffusion of ambient air into the gas stream. It took more than 45min for H2O zero to stabilize. |
