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.
