Measurement data sets
(Refer to Figure 7)
Cumulative measurements made by the instrument apply for the entire measurement
duration. They do not show how the sound level changed during the period of
measurement. The instrument can also make Periodic measurements, which store
measurements acquired during a repeating interval of time. When one interval ends,
the next one begins until the periodic measurements stop.
The instrument's Profile recording function provides an additional time-history
recording channel, which may operate in parallel with either Cumulative or Periodic
data recording. The Profile time history channel can provide faster recording
resolution but for a reduced set of noise parameters.
