In this video we’ll look at how easy it is
to make a noise measurement with the Optimus Red Sound Level Meter. To begin a new measurement, press the Start
button. You now have the option to record a VoiceTag
of up to 30 seconds duration. To start recording, press the Record button or press skip to move
on. When you’re finished, press the Done button
and the measurement will start. On this screen we can see the current A weighted
Leq, the C weighted Peak, the C minus A and a display of the time history. Pressing the right arrow button will move
to the Octave Band view. This screen shows the real time 1:1 octave
band filters for the current measurement. Pressing the Up and Down arrow buttons will
show additional information for the current measurement. Pressing the right hand arrow key again will
move to the noise exposure or dose view. Press the Down arrow button to view the projected
exposure information. Use the left and right buttons to move between
the different information screens. Don’t forget that the instrument is measuring everything
at the same time, regardless of what is on the screen. When the measurement is complete, press the
Stop button. At this point you can use the left and right
arrow buttons to move between the different information screens to review the measurement
data that you’ve just recorded. Press the Exit button and the instrument is
ready to make the next measurement. Here’s a summary of how easy it is to make
a measurement with the Optimus Red sound level meter. Press the Start button.
Record a VoiceTag. View the measurement functions.
Press the Stop button. Review the measurement data.
Press the Exit button. Start a new measurement.

  1. there's one thing missing in this video, and that's if your interested in the max LAS values, make sure that this are in the range of the noise you are studying; don't start a measure right after an event has happened (same if you are in the middle of a measure and you have to pause-rewind) as the levels, in slow weighting, might still be going down and the value registered would be affected by this and end in a invalid measure. Same apply to the voice tags: higher LAS at the beginning by your voice.
    Regards
