| Description: | The instrument was incorrectly installed with an incorrect range setting in the logger
program. The program for lamp calibrating the instrument was used, and not the operational
program. The scale ranges are different, and this resulted in over-ranging conditions
when the signal exceeded the upper end of the measurement scale. Affected times are
centered around solar noon, nominally +/- one-hour around solar noon. This lasted until
mid-Aug, when the highest signals were no longer exceeding the logger range. |
