There was an issue with the dew point generator where it was producing a dewpoint ~16C when the temp switch was set to 20.00C. I calibrated the H2O span the next day on 9/21. We fixed the problem by adding more water in the condenser block on the back of the machine. The water level looked ok while the cap was on and the machine was running, but once I turned the machine off and took the cap off, the water level dropped to below the "Min" line. After I added water and turned it back on, the dewpoint generator got to a reasonable dewpoint and it seemed stable. |

The chemicals were a tad sticky at the top but after a bit of poking with a screwdriver it was easy to dump the chemicals out into the waste jar. I don't think the chemicals needed to be changed necessarily. Before inserting the new chemical bottles, I ran some zero air into the headspace. This run was just to see what the numbers looked like. I will let it run on a bench for a week and calibrate again next week. |

Again the calibrations seem to be right on, but the noise around the set values is two the three times greater than our other IRGAs. I'm planning to send it in for retrofit. |

| LI-190/R Q100421 | 2021-08-25 | Lab none | Installed | Hill Slough PAR Sensor Diffuse | Installed at Hill Slough as part of the rotating shadow band for dfPAR. It replaced sn Q100420. |
| LI-190/R Q100420 | 2021-08-25 | Hill Slough PAR Sensor Diffuse | Removed | Lab none | Removed from Hill Slough dfPAR and brought back to the lab for testing because it was mostly NAN or 0 with some sporadic data. It was replaced by sn Q100421. |
| WMP 1352 000020 | 2021-08-30 | Borrowed none | Returned | Lab none | Returned by Sarah Daniel from LBL FLEXLAB. This is the final item returned. |
| GP-001 GP20160070 | 2021-08-26 | Lab none | Notes | Lab none | Partly cleaned this sensor and tried to take the cable off. However, the connector at the top of the sensor twists loose from the body of the sensor so I don't think it's worth keeping. I'm not sure if the connector was already loose, or if I loosened it trying to table the cable off. |
