| LI-7700 TG1-0421 | 2018-11-05 | Lab none | Upgrade | Lab none | I swapped out power board pn 9677-079G per Licor's instructions. The new power board is pn 9977-079. According to Licor, "the original board needs a new resistor for the "under-voltage" problem (potential to drop out when heater and washers run simultaneously while incoming power is lower than usual, say 11-10 VDC)". The new board Rev 0A (V3) should not have that problem. |
| GP-001 GP20140026 | 2018-11-01 | Lab none | Installed | West Pond CO2 Probe B | Installed at WP to replace sn GP20140018, which was brought back to the lab for too-high readings. |

| LI-7700 TG1-0421 | 2018-11-01 | East End Gas Analyzer CH4 | Removed | Lab none | Removed from EE and brought back to the lab for a power board replacement and calibration. It was replaced by sn TG1-0423 |
| GP-001 GP20140084 | 2018-11-01 | Lab none | Installed | Sherman Wetland CO2 Probe | Installed at SW to replace sn GP20140016, which was removed b/c it was maxing out. |
| Mark I A000591 | 2018-11-02 | Bouldin Alfalfa Weather Station A | Notes | Bouldin Alfalfa Weather Station A | Arable e-mailed to say sn A000591 which has a bad backup temperature sensor and requested we send it back. Not knowing what the exact source of the failure is, and having checked and found no similar behavior in any other device, they want to find out why. We planned to remove this Arable on 2018-10-04, but instead removed sn A000251 from BC and sent that Arable back to the factory. The Arable at BC was replaced by sn A001911. sn A000591 is still at BA for now. |
| Mark I A000251 | 2018-10-04 | Bouldin Corn Weather Station A | Removed | Lab none | Removed from Bouldin Corn to be sent back to Arable for inspection of back up temperature sensor. Replaced by sn A001911. Later we realized we removed the incorrect Arable and they had requested instead sn A000591. |

| LI-7700 TG1-0423 | 2018-10-29 | Lab none | Upgrade | Lab none | I swapped out power board pn 9677-073G per Licor's instructions. The new power board is pn 9977-079. According to Licor the original boards Rev 0, could be damaged by exposure to voltage above 24VDC. The new board Rev 0A (V3) should not have that problem.
Note: This instrument was replaced with 2 original screws and 2 long screws. The long screws were used to help re-assemble the instrument, and I forgot to swap them for the original, shorter, screws. |
