The submenu is used to specify the start and stop times for an alarm campaign (see figure 73).

the ,, and  keys, then validate again.
The name can be at most 8 characters long. Several campaigns may have the same name. The available alphanumeric characters
are the uppercase letters from A to Z and the digits from 0 to 9. The last 5 names given (in the transient, trend, and alarm modes)
are kept in memory. When a name is entered, it may then be completed automatically.
Notes: The start date and time must be later than the current date and time.
The stop date and time must be later than the start date and time.
It is not possible to program an alarm campaign if an inrush current capture is in progress.
Once the programming is done, start the campaign by pressing the key. The icon of the status bar blinks to indicate that
the campaign has been started. The key replaces the key and can be used to stop the campaign before it is finished.
Alarms in progress (not yet ended) are recorded in the campaign if their duration is equal to or greater than their programmed
minimum duration.
