• | User Settings The User Settings dialog box allows you to save the current user settings (your current selection of operational parameters), and to retrieve
factory or previously saved user settings.
|
• | Beam Mode The ME70 collects acoustic data through a number of acoustic beams. The beam properties can be adjusted, and they are collected as beam modes. Each beam mode describes the acoustic properties. You can create and maintain several different beam modes, and use these to set up the ME70 for specific survey activities. The Mode function allows you to activate one of the pre-defined beam modes.
|
• | Range The Range function allows you to specify the maximum theoretical vertical depth covered by the ME70. The range is defined from a selected start range, and down to a value beneath the current bottom depth. The value selected and shown is by default only applied to your active echogram.
|
• | Start Range The Start Range function allows you to specify the start depth of the echogram. The value defines from which depth in the water column the presentation shall start. The depth value shown and selected is by default only applied to the currently selected echogram.
|
• | Minimum Level The purpose of the Minimum Level function is to adjust the echo sensitivity in the ME70 presentations. It controls how weak or strong an echo needs to be to be shown in the echograms. The setting is by default only applied to currently selected echogram. It is identified with a thick border. There are two minimum level buttons, one for each TVG setting (20 log R and 40 log R).
