| LI-7700 TG1-0211 | 2023-06-15 | Hill Slough | Calibration | Hill Slough | Calibration Location: Hill Slough
Last calibration: 2022-11-30 RSSI=73%, Optical RH=23% Ambient P=100.9kPa, Tair=17.0C Zero Air at 1200psi, AMP CA04119 4.2238 at 1000 CH4 Zero Offset: -.003ppm CH4 Span Offset: n/a Notes: Windy! Did not set the span because the sensor value would "stabilize" at different number that would vary by >0.25ppm. The "stable" value would change whenever a gust would blow through. |

Since the optics RH=13% which is pretty good, we did not flush its headspace or change its desiccant. The heater and cleaning settings were set to the default (maybe because of recent power outages). I updated both to what I remember to be our usual settings. |

| LI-7500A 75H-2669 | 2023-04-07 | Lab none | Maintenance | Lab none | Chemical swap. The magnesium perchlorate was a white powdery mass and had to be loosened with a screwdriver before it would all come out. The Ascarite II came out easily. I had tried to calibrate the sensor eariler in the day but the H2O zero offset was -38.3 mmol/m3 and took a long time (45+min) to stabilize. The H2O span never stabilized. |

Attempted calibration on 4/7 but the H2O zero offset was -38.3 after needing a long time (45+min) to stabilize. The H2O span offset never stabilized. I decided to swap the chemicals then and this is the first calibration since chemical swap. |
