Defining the file and folder settings for raw data recording
The ME70 allows you to record raw echo data. The data are saved on the hard disk, or on an external data storage device, according to the preferences you have defined.
Context
The File Setup settings control how and where the recorded files are saved on the hard disk, or on an external storage device. By adding a prefix to the file names you can identify the files you have recorded during a specific mission or survey. You can also define a maximum size of the files.
Tip
The data files will normally become very large. If you wish to record large amounts of data, make sure that you have enough space on your hard disk. Unless your computer is equipped with a very large disk, we recommend that you save the data to an external storage device.
Set up the file and folder parameters before you start the recording. If you wish to save your recorded data on an external hard disk, make sure that it is connected to the computer.
If the current file size gets too big during recording, select Split File on the Record button. This will close the current file, and then automatically continue recording to a new file. Record is located on the Operation menu.
Procedure
