We do not provide support for operation instructions. We are not responsible for any accidents or damage caused by the use of this product.

Please use batteries with a size of 13.75mm or less and 13.70mm or more (※1) for the battery box. ※1 This is within the standard compliance range. ※Batteries sold at private brands such as home improvement stores are often compatible with the above sizes. ※We cannot guarantee that they are always sold at home improvement stores. ※We cannot guarantee that batteries larger than the above sizes will work. Connect to a computer with the included USB cable to display real-time measurement results. Recorded data opened with dedicated software can be graphed and saved in Excel format, which can be used for graphing and data table output. Can be used for noise measurement in factories, homes, and transportation. ◇Usage Notes: When installing the driver on Windows 10, you must configure unsigned drivers. Unfortunately, we do not support installing unsigned drivers. In our testing, we have found that configuring unsigned drivers is not necessary on Windows 8 and Windows 7. However, we will not provide support if installing unsigned drivers becomes necessary in the future. Thank you for your understanding.
