| Subject: | SGP/MET/E15 - Temperature/humidity sensor occasionally failed 6-month field calibration |
| DataStreams: | sgpmetE15.b1 |
| Description: | The temperature/humidity sensor has not been calibrated since 4/7/2009. The temperature reading failed four 6-month field calibration checks during this time, but has passed field calibration checks after 4/19/2011. In general, the relative humidity may have been subject to drift during this time. The manufacturer characterizes sensor drift at <1% / year. |
| Suggestions: | Please contact the mentor for specific information regarding the field calibration check results, if necessary. |
