sound level meter Frequently Asked Questions

A high-speed SD card with a transfer rate of 10 MB/s or higher is required. Also, please do not mix numerical data from regular measurements and sound recording data (in WAV format) on the same SD card.

In the situation described above, if data is saved in that manner, small gaps may occur after deleting numerical data, leading to the possibility of writing WAV data intermittently later, which could result in data loss. It is recommended to format the storage in advance when performing sound recording.

• When using a high-speed data transfer SD card for the first time, please format it in the menu of the sound level meter.
