Customize the USE_LAST_GOOD_VALUE_ON_BAD_DQ key value

Note: For information on overriding default configuration settings, see Modify configuration settings.

This USE_LAST_GOOD_VALUE_ON_BAD_DQ key is used when a bad analog or rate point value is returned. It determines whether the analog or rate point value will be krunched or not krunched and the last known good value for analog or rate point used. If the key value is set to FALSE, then the analog or rate point value is krunched and the value is marked as STALE. If the key value is set to TRUE, then the analog or rate point value will not be krunched, and the last good analog or rate point value will be used. The analog or rate point will also be marked as STALE. For more information on data quality, refer to volume 1 of the RealTime Administrator documentation.
