Enhanced logging software - BZ 7225

With the optional Enhanced Logging Software enabled, Type 2250 is optimised for long-term noise monitoring. It has the functionality of the Logging and Frequency Analysis software but, in addition, it will:

Measure continuously, limited only by data memory and power supply.
Reboot automatically and resume operation in case of power failure
Save data in manageable portions (every 24 hours), selectable for download
Make periodic reports – useful for analysing sound levels over days or weeks
Let you browse easily between markers (like sound recordings)
Measure L_dn, L_den, L_day, L_evening and L_night as required by US and EU regulations

A periodic report is similar to the Measurement Total of the Logging software, except it is made periodically. It is useful for analysing sound levels over days or weeks. If you combine periodic reports with level triggered event markers and Sound Recording (option) you have an overview as well as a focus on essential details.

A typical setup for 24 hours of unattended monitoring might be:

Continuous measurement
Hourly periodic reports
Level triggered marker for events above L_AF = 60dB(A)
Sound Recording of events (Sound Recording Option)
Logging of other parameters as required (Logging Software)

After the measurement, you can check L_dnor L_den, the total and the periodic reports, and then browse the events and sound recordings to verify the quality of your measurements.
