• ढिलो: Provides an averaged reading over a longer period (sampling rate: 1 time/second). Suitable for measuring stable noise levels.

4. Max Hold Function:

थिच्नुहोस् अधिकतम button to display the maximum sound level recorded since the function was activated. Press again to exit Max Hold.

5. Data Recording:

थिच्नुहोस् Rec button to start recording data. The device can store up to 32,000 readings. Press Rec again to stop recording. Recorded data can be downloaded to a computer using the supplied software.
