Archiving
As the Datalogger database grows it will begin to take longer to perform a query. It is recom-

satisfactory performance of the Datalogger program. The archived data will be removed from
the current database, however, you can restore it at anytime. To archive the Datalogger data-
base select Archive from the main menu and then choose the Unit's database to archive. Next,
enter the date range to archive (typically one or more months, a quarter, or year). Follow the
prompts to complete the process. The archived data will be stored in a file that includes the
“from” and “to” date range in a yr/mn/dy format. After archiving it’s recommended that you
Pack the Datalogger database to free memory and reduce the file size. To do this select Pack

Be careful not to exceed the file size limits when combining an archive database with your cur-
