The next step is to look deeper how we can analyze the data being stored.
It's quite simple - just click Analysis button. Since we just stored a data file, DEWESoft assumes this is the file that we want to review. If the user click Analysis in other cases, (when launching DEWESoft or from the setup screen), the file explorer would open up and we can see the sub folders of the main data folder, the file list and detailed information about the chosen file such as size, start store time, version, sample rate, number of channels, storage options and video files (if there are any).
Double click on the file which was previously stored.

If there are sub folders, we can select them by double clicking on the sub folder .
The first level data folder can be changed by clicking on the folder list drop down and selecting any upper level folder. The default folder can be saved by clicking on folder drop down and selecting Set as default project folder.

When the user selects certain file, it is pre-scanned to display important information about channels, events and data header. This information is shown in the General file information section and on the Channel info list below the file explorer. Note that there is also a Min and Max available, and that if the channel is overloaded, this will be shown in red.

 

Now we can open a file. The user can choose any display that was pre-built in Acquisition mode.

There are many ways how to review the data file. On the upper right side there is a Play button . When selecting this, you will see that the yellow cursor moves through the data, FFT is calculated, scope shows the current data and the video file is replayed. When the replay starts, "play" button changes to a Stop button. Clicking to this button stops the replay. We can even hear the sounds we have just stored. By the play button, there is also a Sound button , but with the red cross. Clicking on it displays the channel list. By selecting the only stored channel, the loudspeaker will not have a red cross anymore. Now click the Play button again and whatever was have recorded will be heard from the loudspeakers. Click Stop again to stop the replay, and select None on the loudspeaker icon to switch off the audio replay.

While playing the data, you have noticed that the yellow cursor moves through the data. You can also drag this cursor with the mouse to move through the data file quickly.

 

If the data file is really big, it can be very useful to zoom in on a specific section. Please note that, additionally, the recorder has additional two silver cursors - named  I  and  II . The user can drag these cursors to select a certain region.
