XL2 - The Flexible Solution

Numerous measurement variations are simultaneously available. Actual level (live), Lmin, Lmax, Leq and Lpeak may be measured in combination with frequency weighting A, C or Z and time weightings fast, slow and optional impulse. All results are simultaneously available and may be stored automatically for later documentation.

Customers may log all acquired level information onto a removable SD card. Additionally the XL2 offers wav-file recording for a complete documentation of the measured sound pressure levels. Voice notes may also be added to each measurement.

Real Time Analyzer RTA

The RTA perfectly suits tasks such as optimization of sound systems and rooms. The XL2 measures and logs wideband values and the real time spectrum in 1/1 or 1/3 octave-band resolution according to IEC 61260 class 0. The sound level meter results of the wideband and RTA spectrum are simultaneously available.

Features

  • 1/3 octave, 1/1 octave
  • Frequency weighting: A, C, Z (=flat)
  • Time weighting: Fast, slow and optional impulse
  • Percentile statistics for Lxy (x= A, C or Z, y= F or S ): 1 - 99% (optional)

Data Analysis and Reporting

The XL2 stores all data and audio onto the SD card for direct transfer to the computer. Audio data is stored as .wav files. Data reports and log files are stored in plain text format, which can be opened with any text editor (Notepad, Wordpad, etc). The data is tab-delimited, so dropping the .txt file into a spreadsheet application will conveniently show the results in columns.

A series of free MS Excel application templates provide a convenient way to view the measurement results of specific tasks and create simple reports.
