rent logging run (=cumulative period).

Period: A series of measurements is made at regular user-determined

intervals, and period results calculated and stored. Up to four profiles

may also be stored for each logging run.

Event: Start time (after a user-set delay), duration above a user-set

threshold, maximum sound level reached, time at which reached, SEL

calculated for the event are stored. A 1 sec SPL max. profile of the first

five minutes may also be stored.
