The Event Trigger Method is set to
Level
.
2.
When the measured sound level exceeds the set Trigger Level, an event is triggered and a sound recording
begins. By default, the
Trigger Source
s are set to
SPL 1
and
Peak 1
. The
Trigger Level
s for these 2
sources can only be edited from the Exceedance Triggers page (press left arrow icon twice
).
Alternatively, you may select other
Triggers Sources
from the drop-down menu, and edit the associated
Trigger Levels directly from the Event Triggers page.

The recording saves 7 seconds of sound as indicated in the
Snapshot Time
field. With the checkbox in-
line with
Compression
selected, the sound file is saved using OGG compression. When this is the case,
any email alert notifications sent as a result of the exceedance include the sound recording as an
attachment.
