Key Point 2

No need to repeat your measurements..

The beauty of optimus is that it records every parameter, all at the same time, so there’s no need to worry about having to repeat your measurements to record different values or functions.

This means that if you are looking at the Leq and Peak(C), your instrument is also measuring the Sound Level as well as calculating the noise exposure.
