To determine the horizontal and vertical (3D) coordinates of a ground point by manual aiming to the ferrule of the pin-pole to measure HA and then instruct the robot to search for a prism on the rod to measure vertical angle and slope distance.
This method increases the measurement accuracy by reducing the influence of a possible inclination of the rod from the vertical. A pin-pole prism is also recommended.
Note: Vertical Search Offset mode is only available for survey configurations with a robotic total station.
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 Vertical Search Offset.
Vertical Search Offset mode requires measurement of one location: manual aiming to the point to fix HA and measuring VA+SD.
After taking the measurement, MAGNET Field calculates horizontal and vertical coordinates and stores the point to the job. The stored point has the icon in point listings of the current job. The "V" symbol (Vertical Search) is automatically added to the end of text note for this point.
