Introduction
The SoundPro SE and DL series of sound level meters (SLM) from 3M are advanced
instruments with highly adaptable characteristics. This manual explains the features
and functions of all models in the series and points out distinctions between the
models.
Models and options
There are twelve models in the SoundPro SE and DL series. The differences between
models are accounted for by three primary characteristics: accuracy of measurement,
frequency resolution, and the types of data stored. The table in Figure 1-1
summarizes the characteristics of all twelve models and includes add-on features for
Reverberation, Speech Intelligibility and Acoustic Spectral Curves.
