The NSRTW_mk2 supports a mode of operation where it periodically connects to a server (a Windows PC running the Instrument_Listener application) through WiFi™. This feature is designed to let the instrument record autonomously, periodically report the levels recorded since the last connection, and optionally send emails with noise-level or low-battery alerts. When set, this feature will work, even if the instrument is reset, or if it loses and regains battery power (for instance if the instrument is reconnected to a charger after the battery has been completely drained).

 

This PC-server being connected-to does not have to be in the vicinity of the instrument. It can be a continent apart, as long as it is reachable through the internet, and all firewalls have been set to allow the connection.

 

The instrument connects to a WiFi™ Router or Access Point that is in its vicinity. From there, it will find the server to connect to, either by its IP address, or by its domain name.
