Subject: | SGP/MFRSR/E4 - Erratic head temp and missing irradiance data |
DataStreams: | sgpmfrsrE4.b1, sgpmfrsrE4.a0, sgpmfrsrE4.00 |
Description: | This problem started out with erratic/low head temperature, and expanded to include missing irradiance data. Maintenance on 8/24 had the unexpected result of causing channels 870 and 940 to flat line. The 8/24 maintenance did not fix the head temp problem. On 9/21 maintenance fixed the temp and irradiance issue. Notwithstanding the low head temps, the irradiance data (when available) look OK. However, because the instrument is calibrated and designed to run with temps around 40, be cautious about using data covered by this DQR. |
