Works great
I got somewhere between 40-50 hours of db logging before the batteries died. The instruction manual was good for telling you how to operate the device, however there's not a lot of detail about how to view the data once it's collected.
Familiar with another Omega device I assumed that I was going to need the software. The software is definitely not needed unless you want to chart the data and view it in real time with your PC.
To start logging simply turn on the device, use the manual to choose your device settings (the one thing that I felt the manual did really well was tell you how to set up the device) press record then press logger.
It will start recording decibels into a "Text (Tab delimited)" file with 5 columns of data onto the supplied SD card.
Place Date Time Value Unit
The only value that probably needs a more detailed explanation is the Place value. The device creates a Text (Tab delimited) file and begins recording with the place value of 1, 2, 3,... all the way up to 30,000. Once it reaches this value it creates a new file and begins recording again starting at 1,2,3...
You'll get 2 data files (or more depending on how long you record) and you can then combine all the data into one file and manipulate it with Excel.
It worked great once I figured out how to use the device and to view the data. I hope this helped.
