Use any NL Series Meter with sound pressure waveform recording capability
The -WR option enables high resolution audio recording of up to 24bit audio at 48kHz. The audio recorded can be played back via a computer or can be used with Rion's audio waveform post processing software AS-70 for further analysis.
Sound pressure waveform information is stored on the memory card, there are two recording modes, called event mode and total mode.
Event mode has three recording options: manual recording, level recording, and interval recording.
- Allows recording the sound pressure waveform for any duration during auto store operation. This type of recording is suitable when the operator needs to control the recording function as necessary.
- The sound pressure waveform is recorded automatically when a selected level is exceeded. This type of recording is suitable when higher level sound information should be recorded.
- Recording is carried out at selected intervals (10 minutes, 1 hour), for 15 seconds, 1 minute or 2 minutes. This type of recording is suitable for capturing environmental sound at specific intervals.
- In the auto store setting, all sound pressure waveform information is recorded as long as the mode is active. In the manual store setting, measurement followed by a store operation records the sound pressure waveform for the entire period while measurement is carried out.
The -EX option is required to be installed before the NX-42WR
