Agilaire 8872 Manual
Chapter 2 Configuration
To configure an individual task in the
Task Scheduler
(
Configuration Editors
> Task
Scheduler
), click the
Add
button in the ribbon at the top of the screen and select one of the
following categories:
Alarm Processing Task
reviews alarm Triggers for matches, creates alerts, and tells the
8872 when to process a particular alarm rule. If you use task groups and designate tasks to
run in sequence, you can designate alarms to processed immediately after a data poll.
(Alarm Processing is not used in the 8872.)
Average Data Purge Task
purges or archives old data from the database. Eventually, the
8872 database becomes so big that it takes a long time to back it up, so it is helpful to
remove and/or save old data, in particular minute data. You can choose any average interval
to be scheduled for Purge or Archive. Purged data will be permanently deleted from the
database. Archived data is copied to an external file before purging. Archived data is stored
with all flags and annotations and can be re-imported later.The Model 8872 uses specialized
data keys so sites and channels can be renamed or renumbered and archived data can still be
correctly imported. Select the age of the data to purge:
Purge Data Older Than
a specified
number of seconds, minutes, hours, days, weeks, or years. We recommend purging 1-minute
data older than 1 year to keep the database within allowable size.
Note:
Average Data can be purged manually via the
Utilities menu>Purge Average Data
.
A checkbox option allows you to
retain data during calibrations
. If selected, any data
flagged with the
C
flag will not be purged. This allows you to retain minute data from
calibrations (e.g., for use in the Calibration Trend Graph’s Response Plot) while still
removing old minute data.
