8.6 File Format Description
The sound level meter is using FAT table for file management, and supports FAT16,
FAT32 format, when formatting the SD card, it will turn to default FAT32 format. All
saved measurement result files are saved in a folder, user can name the folder.
Measurement results are saved in a file with the extension name “AWA”. Record file is
WAV format which can be opened through an audio player. Extension name “AWA” file is
a kind of standard text file format, it is recommended to use EXCEL to open the files.
The unrepeated file name is automatically generated by the instrument every time
during measurement. For file name, usually the first three characters represent the
saved content of the file, and the last four characters represent the sequential number
of measurement events. Each time the statistical analysis generates two files,
“STA.AWA” and “NUM.AWA”. If the sequential number of the last four characters is the
same, the measurement results are generated from the same measurement event.
