Subject: | SGP/MFRSR/E27 - Heater problem. Head temp low. |
DataStreams: | sgpmfrsrlangplotE27.c1, sgpmfrsrlangleyE27.c1, sgpmfrsrE27.b1, sgpmfrsrE27.a0, sgpmfrsrE27.00, sgpmfrsraod1michE27.c1 |
Description: | After the logger was replaced in January the head temp never rose to acceptable levels, staying just above 30 deg C. The head is designed to operate at a temp of 40 deg C. Generally it is considered OK within a few degrees of 40, but since this head is operating well below 40 a DQR is being written. It should be noted that the irradiance data look fine, and may in fact be fine, but users should be aware that the instrument is not operating within specifications. |
Suggestions: | Examine data carefully before using. Possible the c1 level data will correct any calibration issues introduced by the lower head temperature. |
