|---|---|---|---|---|---|
| LI-7500A 75H-2514 | 2025-05-09 | Lab | Calibration | Lab | Last calibration: 2025-01-28 AGC=99.6 SDM=7 DAC1=- DAC2=- AIU sn AIU-2652, Presure A0=59.516, A1=15.503 Ambient P=100.8kPa, Tair=16.9C, Tdew=8.9C Zero Air at 100psi, AMP CA03923 488.75 at 1200 Tdewspan=13.0 CO2 zero 0.9083 -> 0.9091 Offset: 3.4ppm CO2 span 0.9983 -> 1.000 Offset: -0.95ppm H2O zero 0.8498 -> 0.8479 Offset: -12.7ppm H2O span 0.97 -> 0.9976 Offset: -0.57ppm Notes: The CO2 span was finicky. Tried a couple of small offsets from span gas value but there is anecdotal evidence that coefficient near 1.000 are difficult. Overall okay. |
| LI-7500A 75H-2667 | 2025-05-08 | Lab | Calibration | Lab | Last calibration: 2025-01-07 AGC=99.5 SDM=7 DAC1=- DAC2=- AIU sn AIU-2652, Presure A0=59.516, A1=15.503 Ambient P=101.0kPa, Tair=19.1C, Tdew=9.8C Zero Air at 100psi, AMP CA03923 488.75 at 1200 Tdewspan=13.0 CO2 zero 0.941 -> 0.9418 Offset: ppm CO2 span 1.0165 -> 1.0218 Offset: ppm H2O zero 0.8454 -> 0.8421 Offset: ppm H2O span 1.0393 -> 1.0332 Offset: ppm Notes: I started to calibrate this head yesterday but the H2O zero offset was large ~-30 and opposite for the third time. I decided to swap the internal chemicals - they were hard and needed a screw driver to pry out of the bottles. I tried to flush the body with zero air but the zeros were still high ~18ppm CO2. I let it run overnight. The chopper is a little noisy and I had to use 0.1ppm less to get the CO2 span to read right. |

| LI-7500 0976 | 2025-05-02 | Lab none | Upgrade | Lab none | I upgraded this unit from 7500 to 7500A by replacing the bottom interface plate. Following the instructions I also adjusted the AGC pot and changed the signal strength coefficients. I also swapped the internal chemical - they were pretty hard and needs prying with a screw driver to get them out of the bottles. I'll let the head run over the weekend before I calibrate it. |

I reset signal strength from 76.1 to 100.0. H2O span was less stable than I would like. The original config file downloaded from Licor was use with co2 zero = 0.8579, co2 span = 1.000, h2o zero = 0.6231, h2o span = 0.9943. SD coefs set to zero. |

Touched up scrapes on spars with nail polish |
| CS450 20010770 | 2025-04-15 | Lab none | Tested | Lab none | I tested this sensor in the lab. Its power draw was hanging up a CR1000 or maybe the Lithium power pack. I tested it on the lab power supply and it was pulling 1.4A when it should be more like 80uA. The cable is pretty beat up with lots of tape patches, cracking and one abraded spot with the internal conductors visible. Not sure if it is worth cutting off the worst parts of the cable and trying it again. |
| CS450 20010770 | 2024-12-19 | Bouldin Corn Water Level | Removed | Lab none | Removed from BC because it was shorting out all the 12V power. |

| URM06 URM06-002 | 2025-01-15 | Mayberry Range Finder water | Removed | Lab none | Removed from the tower for a newer maybe better one. The water level range data from this sensor is a bit noisy but useful for gap filling. |

| MiniCH4 38-572-25 | 2025-03-13 | Lab none | Tested | Lab none | I ran this sensor in continuous mode for 10s of minutes and it never stopped reading -10 for CH4. I removed the filter and didn't seen any obvious signs in water getting in. Need to contact ProOcenanus. |
| MiniCH4 38-576-25 | 2025-03-13 | Lab none | Tested | Lab none | Tested in the Lab. Seems okay. The CH4 was reading near zero 0.02% and I could make it climb by breathing into the filter. |
| MiniCH4 38-574-25 | 2025-03-07 | Lab none | Installed | Gilbert Tract CH4 Probe Channel | Installed at the GT channel to replace sn 38-576-25 that has been reading -10% CH4 |
| MiniCH4 38-576-25 | 2025-03-07 | Gilbert Tract CH4 Probe Channel | Removed | Lab none | This one started reading -10% CH4 for no apparent reason. It was removed for testing and replaced by sn 38-574-25 |
| MiniCH4 38-572-25 | 2025-03-07 | Mayberry CH4 Probe | Removed | Lab none | This sensor had fallen out of the cable ties and its sensor may have been in the sediment. The CH4 readings steadily rose past 4% but it was dropping out before climbing. Removed for testing. |
