Alarm Trend Data
In addition to the interval trend data, the GX-2009 also saves
files that describe the most recent gas alarm events. If a gas
alarm event occurs, then an alarm trend file that is centered
around the event is saved separately from the interval trend data
files. It shows the readings up to 30 minutes before and 30
minutes after the event, with the log interval time every five
seconds. The gas readings logged at the alarm event time are
highlighted in red and the gas readings logged every 5 seconds
around the alarm event are the peak (minimum for oxygen)
readings for the previous five seconds. If the GX-2009 has not
been on for 30 minutes before the alarm event occurs, the data
during this time is left blank. If the GX-2009 is turned off less
than 30 minutes after an alarm event occurs, the data file will
only have logged data until the unit was turned off.
The GX-2009 saves up to 8 alarm trend files. When an alarm
event triggers an alarm trend file to be saved, subsequent alarm
events must occur 15 minutes after the previous triggering event
in order to trigger the saving of another alarm trend file. If 8
alarm trend files are already saved in the GX-2009’s memory,
the oldest alarm trend file is overwritten when a new alarm trend
file is saved. Alarm trend data can always be displayed in either
table or graph format.
