Pulse Laser Station NPL-302 Series Instruction Manual 71
Setting up a station using multiple point resection 40.1
A resection sets up the station using angle/distance measurements to known points.
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.
The F2 softkey is not available on the NPL-332.
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. For geometric reliability, select known point locations (or
station point locations) that are widely spaced.
