Logged Data

Logged measurements compute the peak, maximum, minimum, sound exposure, and average values over a run-time at the user selected logged interval.

When in a run (or a session), logged data is automatically stored in the instruments memory. The summary data is viewable on the display of the instrument while the logged data is viewable in DMS. Below is an example of DMS’ logged data chart.

Windscreen

The SE-400 Series features a removable windscreen, which is primarily used to help reduce noise effects from wind with minimal effects on the readings. It is recommended to place and use the windscreen over the microphone at all times to help protect the microphone.
