14.RESECTION MEASUREMENT
Resection is used to determine the coordinates of an instrument station by performing multiple measurements
of points whose coordinate values are known. Registered coordinate data can be recalled and set as known
point data. Residual of each point can be checked, if necessary.
• Between 2 and 10 known points can be measured by distance measurement, and between 3 and 10 known
points by angle measurement.
• The more known points there are and the more points there are whose distance can be measured, the higher
the precision of the coordinate value calculation.
• It is possible to allocate Operating icons in measurement menus to suit various applications and the ways that
different operators handle the instrument.
