threshold may be set by the user.
The Start Date and Time, Affected Phase(s), and Duration of each swell are displayed.

5.2.9 - Alarms Menu
This menu stores and displays the last 5 alarms to go off (if any did go off) (For Alarm Setup, see Sect. 4.2.11).
The menu automatically displays the page of the most recent alarm.
Each alarm is identified by:
●
Start Date and Time;

type of parameter that exceeded the thresholds set;
●
value of the parameter which caused the alarm to go off;
●
duration of the event.
To view any previous alarms, scroll through the relevant pages using the

falls within the set values again.
