| LI-7500A 0073 | 2022-04-08 | Lab | Calibration | Lab | Last calibration: 2022-03-30 AGC=98 SDM= DAC1= DAC2= Ambient P=100.8kPa, Tair=28.9C, Tdew=11.3C Zero Air at 775psi, AMP CA04119 524.77 at 1600 Tdewspan=20.00 CO2 zero 0.9164 -> .9163 Offset: -.24ppm CO2 span 1.0039 -> .9983 Offset: 4.11ppm H2O zero 0.827 -> .8246 Offset: -13.5ppm H2O span 1.0223 -> 1.0147 Offset: .17ppm Notes: During the H2O span, H2O value was trending downward after a while. I added more DI water to the reservoir, and the H2O value stabilized. |
| LI-7500A 1594 | 2022-04-08 | Lab | Calibration | Lab | Last calibration: 2021-11-30 AGC=96.7 SDM= DAC1= DAC2= Ambient P=100.6kPa, Tair=30.8C, Tdew=11.2C Zero Air at 725psi, AMP CA04119 524.77 at 1600 Tdewspan=20.00 CO2 zero 0.8645 -> .8643 Offset: -.71ppm CO2 span 1.0128 -> 1.0097 Offset: 2.12ppm H2O zero 0.8877 -> .8891 Offset: 7.7ppm H2O span 1.0045 -> 1.0106 Offset: -.13ppm Notes: |

In the lab the SS was much more normal ~100. I'm not sure why there is a difference, as the config file should be the same. |
| PAR-LITE 040411 | 2022-01-20 | Lab none | Damaged | Lab none | Brought to EE to install as part of the dfPAR set up, but killed the sensor when I accidentally wired its red/black wires into power |
| WM 1590 153804 | 2022-04-06 | Lab none | Tested | Lab none | I tested this sensor briefly in the lab against sn 152601. U and V had a much smaller magnitude. I checked the analog settings and they had been set to 5m/s range. I changed U and V from 5m/s to 30m/s. I left W as 5m/s. U, V, W, SOS seem reasonable. I will be moving this intercomparison to my backyard tomorrow to run for a few days outdoors. |

| HMP155 T2820183 | 2022-03-10 | Lab none | Installed | West Pond RH & Temp | Installed at West Pond to replace the malfunctioning one removed last week. Broken mounting screw and typo in the data logger program - messy troubleshooting ensued. |

| LI-7550 AIU-1285 | 2021-12-02 | Lab none | Tested | Lab none | Tested in the lab and this interface ran fine when connected with another LI-7500A. The problem of no CO2/H2O data was caused by the LI-7500 sn 0418, not by this interface. |

| LI-7500A 75H-2514 | 2022-03-09 | Lab none | Maintenance | Lab none | We ran zero air through this sensor today. The CO2 zero was fine at 1.21 ppm. The H2O zero was large at -26.8 mmol/m3 (previous H2O zero from last week had a +30.2 mmol/m3 offsets). In addition, the H2O zero changed depending on the orientation of the sensor. When laying on the bench, it was around -20 mmol/m3. When the top of the sensor was propped up slightly, the offset jumped to around -10 mmol/m3 and stayed steady. When we laid the sensor down again, the offset dropped to -20 mmol/m3 again. Joe didn't hear anything change inside the sensor when we were moving it around. We decided to change the internal chemicals. The old chemicals seemed ok. We flushed out the headspace with zero air before sealing it up again. I'll let it run on the bench for a few days before calibrating it again. |

Not really sure why it's difficult to get a good calibration. Is the sensor changing that much between calibrations (even though it's just been sitting in the lab)? Or is there something inconsistent about my calibration method? |

| LI-610 DPG478B | 2022-02-28 | Loaned none | Returned | Lab none | Returned from Katerina back to us. There is an issue with the flow rate and it doesn't seem to go above 100 cc/min. There's enough water in the reservoirs and the condenser seems to be doing its job. I tried swapping out the internal air filter with a brand new one (borrowed from the UCSC kit), but that didn't make a difference. I don't think the rate was diminishing over time, so it makes sense that the internal air filter was fine.
Probably the problem is with the air pump diaphragm. The manual says that "A pump that is functioning normally will generally output a pressure of 450 to 600 mb, when measured at the TO CONDENSER port." I'm not sure how to measure that pressure (with something like a tire pressure gauge?) but I should probably check that before taking the pump apart. I changed the air pump diaphragm following the instructions in the manual and all seems well. |
