Offset measurements are performed in order to find a point where a target cannot be installed directly or to find the distance and angle to a point which cannot be sighted.
• It is possible to find the distance and angle to a point you wish to measure (target point) by installing the target at a location (offset point) a little distance from the target point and measuring the distance and angle from the survey point to the offset point.
• The target point can be found in the three ways explained in this chapter.
• The instrument station and backsight must be set before the coordinates of an offset point can be found. Station and backsight setup can be performed in the Offset menu.
Occupy setup: "14.1 Entering Instrument Station Data", Backsight setup: "14.2 Azimuth Angle
Setting".
• It is possible to allocate softkeys in measurement menus to suit various applications and the ways that different operators handle the instrument.
