Note 1: With “Series 3 & 2" instruments, period Ln values are calculated when a run is ≥ 1 minute
in length. (”Series 1" instruments need at least 4 minutes for broadband and 8 minutes for
narrow band.) Cumulative Ln values will be available for display as soon as a broad band
run ≥ 5 seconds duration or a narrow band run ≥ 10 seconds duration is complete.
Note 2: Available only with periods of 5 minutes or longer.
