Resection
The resection program calculates the new point (occupied point) coordinates from two known point
numbers with coordinates that are stored in a job. The angle and distance is measured to each known
point and the residual error for the horizontal distance and vertical distance are shown on the display. If
the software can not calculate the new point, the massage (Calc Error) appears. Once the residual
error is accepted, the next display shows the coordinates for the new point. When the coordinates are
viewed in the job, the record number is shown in a box, ( 10 PT#: 12).
The example below shows how to compute the resection point.
Operating procedure
1
Press [F3] for the New Point option.
2
Press [F2] to compute a resection point.
3
This screen allows the user to type in a point
number for the new resection point. After
typing in the print number press the (ENT)
key to continue.
4
Input the instrument height. Type in the
instrument height and press the (ENT) key.
5
Enter the first point number to measure that
will be used to calculate the resection point.
6
Enter the prism height and press the (ENT)
key.
7
Sight the instrument on to the first point. Once
the instrument is locked on the point, press
the [F5] key to measure the angle and
distance. The [F6] key will return back to step
5).
