SGP/EBBR/E15 - Questionable data due to low voltage at E15

On November 11, 1993 at 0300 GMT the voltage level of the battery for the
EBBR at Ringwood (E15) dropped to too low a level for most of the
sensors to perform properly.  By 0700 GMT virtually all sensors were not
indicating properly.  This condition continued through 1830 GMT on November
15, 1993.  No data from this EBBR should be considered valid during the
period indicated, since the quality of data from all sensors is
questionable.
