Alarm Trend Data
In addition to the interval trend data the GX-2001 also saves a file which
describes the most recent event during a particular session.If an event
occurs, then an alarm trend file is saved separately from the data file, which
shows the reading 15 minutes before and 15 minutes after the event, with
the log time every five seconds.
When an event occurs and an alarm trend data file is saved in the GX-
2001, this file remains in the unit’s memory until another event occurs.
When another event occurs, the alarm trend data file is overwritten with the
new event’s information.
Alarm trend data can always be displayed in either table and graph format.
