To determine the horizontal and vertical (3D) coordinates of an inaccessible point using distance and angle measurements to two prisms located on the slanted rod touching this point.
To enter this offset mode, click in the top left corner of the Topo Survey (Optical) dialog, click Measure to expand the sub-menu and select Hidden Point.
Hidden Point mode requires measurements to two prisms on the rod: HA+VA+SD measurement to the top prism and HA+VA+SD measurement to the bottom prism.
Note: Enter the distance between the pole tip and the bottom prism in the HR (height of the target) field.
After taking two measurements, MAGNET Field checks the tolerance (if enabled), then calculates horizontal and vertical coordinates and stores the inaccessible point to the job. The stored point has the icon in point listings of the current job.
