When the trigger function detects an event, identified by the overcoming of the trigger thresh-
old, or when ENTER is pressed, a time marker is recorded.
Similarly, when the end of event conditions are sensed, as identified by the deactivation
threshold being reached, or by the external TRGIN signal, or when ENTER is pressed, and after the
set stop delay has elapsed, another time marker is recorded. After the time marker, when the event
is closed, the record containing the Event group information is logged.
When the event trigger uses the Profile view sound level as source (Menu >> Trigger >>
Source: LEV), the event data are recorded only when the trigger threshold (Menu >> Trigger >>
Trigger Threshold) exceeds the minimum duration time (Menu >> Trigger >> Minimum Duration).
The following figure shows the recording flow for the Measurement, Report and Event
groups. The Measurement group recording is enable only during the event; outside the events, only
Reports are recorded. In the following example a report is recorded every 10s.

When the trigger threshold is exceeded for a shorter period than the minimum duration time, the re-
cord containing the Event group information is not logged.
