This standard software, included in the basic package for Types 2250-S and -W and 2270-S and –W, provides a single, wide dynamic range that is combined with simultaneous measurement of RMS and peak levels with different frequency and time weightings so you can gather all information in one go.

The sound level meter template also offers a large, easily visible display for more accurate measurements – for example, observing measurements from a distance removes acoustic reflections from your body that would influence the measurement.
