To define an area, click the String Measure button. Click anywhere in the sonar view to start a point. Move to the second point, then click again. Click as many times as necessary to create the required area. Double-click on the last point to finish. The area will automatically be closed, and a rectangular label will appear providing information about the area and perimeter. Move the label to a position on the screen where it is most legible, then click the left mouse button to place it.
Tip
You can place multiple areas on the display. The areas will remain on the display until you delete them individually with the Wiper function.
