7 OFFSET SHOTS
General pictures of measurement
OFFSET SHOTS can be used when the Prism cannot be positioned because of an
obstacle in the way. With this type of measurement, the Target coordinates are measured and
stored indirectly. Coordinates values input can be omitted by designating the Station point number
whenever the Station coordinates are stored in the internal memory.
