CEL633C Sound Level Meter

Measurement Stores

The CEL633C comes with a number of noise measurement stores:

Time History - usually set to a fast rate, such as 1 second, to provide a detailed graph of the sound level over time
Periodic Measurements - usually set to 5 minutes, 15 minutes or 1 hour depending on applications. Can also be fixed periods. These are the most important environmental noise measurements, including parameters such as LAeq, LAmax and LA90.
1/3 Octave Band - storing the frequency analysis spectra
Audio Recordings - recordings of the actual sound so you listen and make a positive identification of the noise source.

All these measurement stores are included with the CEL633C sound level meter, even if you choose not to buy the additional software. There is more information below about the different download options.

The more advanced Insight software can be downloaded free of charge for 30 days in case you are not sure whether you need the extra reporting features that it offers.

CasellaDrive Free Software

When the CEL633C sound level meter is connected to a computer it works like a memory stick, so there are no complicated driver installations. However, the files are coded and compressed so you won't be able to read them directly.

The CasellaDrive software decodes the files and makes them available to copy into Excel or any similar spreadsheet program.

Most files are simple Comma Separated Text (CSV) files that can be read into many different programs. Audio recordings are in the standard WAV format, to be listened to using standard media playing applications.

More information on the CasellaDrive page.

Insight Software

The Insight software is an option that can be purchased with the meter or at a later date. A trial version can also be downloaded - this is a full featured version of the software but time limited to 30-days, after which time you need to buy a licence to continue using it.

This software downloads the measurements from the sound level meter, storing them on your computer. You can carry out analysis of the sound levels and produce a number of reports.
