| CMP 11 996981 | 2023-08-03 | Lab none | Repair | Lab none | I took this pyranometer apart and soldered a new short cable to the contacts on the bottom side of the sensor. The wiring colors are the same: red+, blue-, shield. There was a white wire that doesn't seem to be used which I replaced with a yellow so that it is accessible outside the case. It needs new desiccant and probably a longer wire spliced on to be used on a tower. There is a scratch on the outer dome and it needs an inter-comparison. |

| 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. |

Flushed headspace to 12% optics RH after calibration and swapped in a new desiccant bottle. |

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. |
