Local Measurement Data

Data saves internally to the monitor and once a cloud connection is established, the data is sent and processed in our cloud system to give you real-time access and alerts via SMS and Email depending on the user preferences.

The unit can be setup to measure Lmax LAeq L10 L90 with A or C weightings. The unit can log in 1 minute intervals up to 1 hour. Octave and thirds can be collected on a device enabled with the frequency option. Audio recordings can be captured on the device and uploaded to the cloud for Automated Noise Identification with the Audio Capture option with pre and post trigger settings available in the menu.

Enable low power mode and limit the WiFi hotspot period from always to a time you wish to set to save power. Simply reset the device to reissue a WiFi hotspot period.

Calibration

To calibrate your noise monitor you will need either a 94 dB or 114 dB calibrator with a 1/2 microphone input or adapter. Place the calibrator on the end of the microphone and navigate to the monitor control panel via your mobile phone.

Connect via WiFi to the device by the displayed name Sonitus Systems 00123 (Serial Number) and enter the password. Once the password has been accepted (can take up to three attempts), proceed to the calibration panel and enter the output level on the calibrator and define the calibration test period, normally minimum 20 seconds is recommended. After 20 seconds, the unit will ask you to apply the change and will reboot.

Jubiliee Clips

Slide the two jubilee clips and pole supports through the rail to fix to a pole. Do not over tighten the jubilee clips. 

Microphone Mounting Using S Pole

The microphone can be attached to the S pole using zip ties or jubilee clips. Run the cable down the pole. Mount the S pole to the back of the noise monitor slotting the bracket into the back of the rail (use a spacer washer to allow sufficient room for the bracket.

Pole Mounted Noise Monitor

When installing your noise monitor, keep it as free-field as possible away from trees and obstacles. If you must install it within 1 metre of any reflective surface, it is possible to apply a reduction adjustment to the input sensitivity to account for reflections which increase the sound level.
