4 Applications You can use a maximum of 10 points in a resection. Measurements can be distance and angle, or angle only. Calculation starts automatically when enough measurements are taken. You can delete poor observations and recalculate if necessary. You can also select the BS point. B Tip – If the angle between known point 1 and known point 2 (measured from the station point) is extremely acute or extremely oblique, the resulting solution will be less reliable geometrically.
4 Applications 7. Measure to PT2 and press [ENT]. When the instrument has enough data, it calculates the station (STN) coordinates. – If more than the minimum required data is available, a standard deviation screen appears. – To take measurements to strengthen geometry of the resection, press the Add softkey. For information about the View softkey, see Advanced feature: Viewing and deleting a measurement in resection, page 67. 8. When the results are satisfactory, record the station.
4 Applications B Tip – The minimum data required for a resection is either three angle shots, or one angle shot and one distance shot. If you use a distance shot, the distance between the target points must be greater than the measured distance. Stn-Z is calculated from distance-measured data. If no distances are measured, then Stn-Z is calculated using angle-only measurements to points with 3D coordinates.
4 Applications – To reset the horizontal angle, enter a value in the HA field and then press [ENT]. – If you do not need to reset the horizontal angle, leave the HA field blank and then press [ENT]. The Stn Setup menu appears. Remote BM Select this option to determine the station elevation. 1. Press [4] or select Remote BM from the Stn Setup menu. 2. Enter the BM point and press [ENT].
