When using 1s interval setting – don’t use the threshold to trig recordings. • When using threshold on the Leq channel – don’t setup shorter interval time than 5 minutes. • Contact Sigicom support if you need to violate any of these limitations. Copyright ©Sigicom AB 2018... -
Page 9: General Description
The Sensor Cable supplies the S51 Sound Level Meter with both electrical power and all necessary communication. To present data correctly, use the latest firmware in the INFRA Datalogger (1.15.1-1.15.1 or later). A Sound Level Meter connected with INFRA Datalogger in a minimal configuration.

S51 Sound Level Meter handles two time constants: • 0.125 seconds for time weighting F (FAST) • 1 second for time weighting S (SLOW) • No time weighting (PEAK) One of the time weightings can be selected at a time. Copyright ©Sigicom AB 2018... -
Page 12: Level Ranges
One of the level ranges can be selected at a time. 3.5 Display devices S51 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 2018... -
Page 13: Interval Files
In order to enable long cables and low power of the communication, the transfer capabilities between S51 and the Datalogger are rather slow. It transfers approx. 0.15 s of S51-data per second or 0.4 s of vibration sensor data per second. Copyright ©Sigicom AB 2018... - Page 14 • 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 2018...

3. Every time you press F2, the “Live-value” is updated. 4. If you have several nodes connected to your Datalogger, press ▲ or ▼ until the “Live-value” of your S51 is displayed. Read more about the Live functionality in the Infra Master Manual. Copyright ©Sigicom AB 2018... -
Page 24: Consider This
Use the included windscreen to prevent undesirable wind noise to be added to the measured signals. • The sensor cables supplied by Sigicom are designed to work properly with the system. Please don’t use other types of cables. -
Page 25: Post-Processing Of Data
Post-processing can be done in the web application InfraNet. • Data is sent from the Datalogger to an Internet accessible database server where each Infra customer has its own database instance. • See further in documentation of the InfraNet application. Copyright ©Sigicom AB 2018... -
Page 26: Maintenance And Calibration
7 Maintenance and calibration • Send the device to Sigicom AB for calibration and adjustment. See contact information below. Recommended calibration interval is 12 months. • If sent to repair, please carefully write down the description of the problem. It is also recommended contacting Sigicom before sending the unit for repair. -
