Browsing through measurement data works a little differently than in other modules, since
the amount of data associated with a measurement file can be very large. In many cases, it
will not be practical to inspect the data from the device itself, and data will be downloaded
to a PC first.
The blue buttons are used to browse through all earlier log files stored on the device. Note
that each file may span anywhere between a few seconds and many hours, depending on
how much time elapsed until the "stop" button was pressed. Within each file, you can scroll
through the data with the red arrow buttons (single arrow to scroll line-by-line, double
arrow to quickly scroll page-by-page). Each line shows the time, the current level for the
corresponding measurement interval, the average LAEQ and an indication whether or not
the limit was exceeded.
Long sessions may be broken into multiple files by pressing stop and (immedi-
ately) again start. If the device crashes unexpectedly (e.g. in case of power fail-
ure), there is a chance that (part) of the log file may be lost. By breaking the
session up in multiple files, the risk of losing data is reduced.
For long sessions (>3 hours), you will need to power the device from an external
power source (such as a PC, power bank or the USB charger).
Note that the log file contains more information than shown on the device. In
particular, not just the time but also the date is stored. Make sure that the date
and time are set correctly (though the settings module).
