3.3 Time weightings S50 Sound Level Meter handles two time constants: 0.125 seconds for time weighting F (FAST) 1 second for time weighting S (SLOW) One of the time weightings can be selected at a time. Copyright ©Sigicom AB 2003-2014... -
Page 13: Level Ranges
One of the level ranges can be selected at a time. 3.5 Display devices S50 Sound Level Meter shall be connected to the INFRA Field Monitoring System which has several capabilities of displaying the measured signals. The resolution is 0.1 dB. Copyright ©Sigicom AB 2003-2014... -
Page 14: Interval Files
In order to enable long cables and low power of the communication, the transfer capabilities between S50 and the Datalogger are rather slow. It transfers approx. 0.15 s of S50-data per second or 0.4 s of vibration sensor data per second. Copyright ©Sigicom AB 2003-2014... - Page 15 If the recording length is set short, the transient memory will be splitted into two or more transient files. This enables that more than one transient file may be recorded before the memory becomes full. Copyright ©Sigicom AB 2003-2014...

The definitions used here are described in the standards IEC 61183 and ANSI S1.10. Free-field frequency characteristics of the measured sound pressure level for various angles of incidence. The calculated random incidence is also illustrated. Copyright ©Sigicom AB 2003-2014... -
Page 17: Mounting
This short distance implies that the measured sound pressure level (of the lower frequencies) will be 6dB higher compared to a situation See section 8 Accessories. Copyright ©Sigicom AB 2003-2014... - Page 18 6 dB increased measurement is not done in the S50, but can be setup in the post-processing. Measured sound pressure level as function of the frequency because of total reflections for three distances between the center of the microphone and the wall (sinusoidal sound wave).
