This periodic change in the bias voltage is part of the normal operations of SEM and is not an indication of any problems. As the detectors age, it is important to increase the bias voltage to compensate for reduced sensitivity. This increase will improve the performance of the SEM TED detectors. ** *Contact Information for Further Information:* ESPC Operations at ESPCOperations@noaa.gov at 301-817-3880.** *Web Site(s) for applicable information:*N/A This message was sent by ESPC.Notification@noaa.gov.
