INTENDED USE

The SE-400 Series Sound Level Meter is intended to measure sound pressure levels in air
and provide sound and noise detection measurements. It is fitted with12 keys for powering
on/off, viewing and/or running/stopping measurements, navigating and setting parameters
(See Figure 1 for more information). For suitability and proper use follow local regulations and
refer to all information supplied. For more information contact a safety professional/3M
