A-, C- or Z-weighted signal from the measurement transducer
The average level of the signal is kept within a 40 dB range, or the gain can be fixed
Sound is buffered for the pre-recording of sound. This allows the beginning of events to be recorded even if they are only detected later.
Manual Control of Recording: Recording can be manually started and stopped during a measurement using a push button or an external signal
Automatic Control of Recording: Start of recording when measurement is started. Minimum and Maximum recording time can be preset.
Manual Control of Recording (using Manual Event or Back-erase push button, or an external signal): Recording during all of the event, or for preset minimum and maximum duration. A Sound marker is set while recording. Selectable pre- and post-recording time
Manual Control of Recording (using touch screen): Recording for the selected time period (subject to the limitations of the pre-recording buffer). A Sound marker is set for the selected time period.
Automatic Control of Recording: An event can be triggered when a broadband level is above or below a specified level. Recording during all of the event or for preset minimum and maximum duration. Selectable pre- and post-recording time
Automatic control or Recording: Start of recording when measurement is started.
Playback of sound recordings can be listened to using the earphone/headphones connected to the headphone socket.
The recording format is 16-bit wave files (extension .wav) attached to the data in the project, easily played back afterwards on a PC using Type 7815, 7820 or 7825. Calibration information is stored in the wav file.
