SD-200 Overview
SD-200 Overview
The SD-200 is intended to provide measurements of sound pressure levels in air.
With five easy-to-use keys, the keypad is used for powering on/off, viewing and/or
running measurements, navigating, and setting parameters. (See Table 1-2 for
more information.)
Note: for typical sound measurements when determining hearing protection,
the SD-200 may be set to “A weighting” with “Slow” response.
