•Peak: Crosshair will be displayed, and its location is automatically drawn at the

peak energy location of the beam. Note: This operation will not function correctly if the results window is minimized.

•Origin: The Crosshair will locate to the position of the Origin.

Note: The Crosshair might not be displayed if the Origin location is outside the display window, or it might be in an upper or lower left corner.

To manually position the Crosshair, use the mouse to drag and drop it. Move the mouse pointer to the intersection point of the Crosshair.

When the pointer changes to the Crosshair drag symbol, , press and hold down the left mouse button and drag the Crosshair to a new location. Release the mouse button to drop the Crosshair.

The Crosshair can also be used to position the Manual Origin Location. If the Origin is set to Manual mode, and the Crosshair set to Origin, if you drag and drop the Crosshair the Origin will move with it.

Note: It is possible for the Crosshair/Origin to be outside of the current viewing area of the Display and thus not visible. Check the Pan/Zoom windows red dot to locate the origin.

3.2.7.13.3Grid

Check this item to cause an X/Y Grid to overlay the display. The Grid scale will vary based upon the spatial calibration setting. You can use the Grid to make rough distance measurements.

3.2.7.14 3D only

The following Beam Display dialog box items only have an effect on the 3D beam display.

3.2.7.14.1Wire Frame / Crosshatch

The 3D beam display is drawn as a wire frame. The above two check items will cause the wire frame display to have wires running only in the horizontal direction, or in a crosshatch pattern. If just the Wire Frame item is checked, the display will consist of wires running only in the most horizontal direction. If Crosshatch is also checked, the display will be crosshatched. In 3D mode, either Wire Frame or Contour (see below), must be checked.

Hint: Your display will run faster if only Wire Frame is checked.

3.2.7.14.2Contour

Check the Contour box if you want to see your beam display in a contour map style. When you turn on the Contour mode the Wire Frame/Crosshatch style display will change from
