SV 307 User Guide
5
In accordance with best measurement practices and ISO 1996-2 if measurements
take place over longer periods of time, e.g. over a day or more then the meas-
urement system should be checked either acoustically or electrically at regular
intervals, e.g. once or twice a day.
Following the ISO 1996-2 recommendations the SV 307 has been equipped with
an
Acoustic System Check (ASC)
that can be activated remotely; either auto-
matically or upon manual request. The ASC is located in the top of the tube direct-
ly above the microphone of the SV 307.
System Check
The ASC is based on a small speaker and the three MEMS microphones in the
SV 307. Activation of the ASC enables the speaker and triggers an alarm if any of
the three MEMS microphones reports a different noise level than the others.
Remote System Check
System check configuration is available in SvanNET Configuration tab. Simply go
to SvanNET / Configuration / Calibration - Automatic System Check to schedule
the system check time.
System Check in SvanNET APP
To perform a manual system check simply open SvanNET application, select your
SV 307 station and click the System Check button.
