Option 6: Level versus time measurements

  • Print
  • Measures the time “Profi le” (level vs. time) of the noise signal with preset time resolution simultaneously with the overall “Global” measurement
  • Selection of preset intervals within the 1 second to 199 hours interval range
  • Automatic level versus time storage of LAeq, LAmax and LCpeak (or LZpeak)
  • Automatic multispectrum storage of Leq and Lmax if option 1 is installed
  • Level versus time measurement continues during a paused Global measurement
  • Markers identify any pause, stop or continue of the measurement
  • Real-time graphical and numerical display of the level versus time results

Automatic markers:
A pause marker is inserted into the time profi le in pause mode. A recorder marker is inserted when the instrument is doing a sound recording, and an overload marker is inserted if overload occurs.
