before an alarm event or is not on for 15 minutes after the alarm event,
only the time that the unit was on is shown in the alarm trend file. If a
GX-2003 or the GX-2009 has not been on for 30 minutes before the
alarm event or is not on for 30 minutes after the alarm event, only the
time that the unit was on is shown in the alarm trend file.
Once the maximum number of alarm trend files are already saved in an
instrument’s memory (one for the GX-2001 and 8 for the GX-2003 and
the GX-2009), the oldest alarm trend file is overwritten when a new alarm
trend file is saved. If an alarm trend file is overwritten before data is
downloaded to the Data Cal 2000, that file is lost. At least two data points
must be saved for the alarm trend file to be viewable in both table and
graph format.
To view and perform desired operations with the alarm trend files:
1. While in the Logs window, open folders in the left side of the
window until the Alarm folder you wish to open is visible.
2. If you are viewing data in base view format with the data organized
by type, expand the Alarm folder. Folders organized by year/month
will appear below the Alarm folder. Click on the folder whose
contents you wish to see. The alarm trend files in the folder will be
shown in the upper right side of the Logs window.
