MEASUREMENT FOUNDATION

Ruber-X32

2) Elevation between A and B points is computed as the sum of elevations of all sections.

General formula is following:

Height of determinated point=

Height of giving point+

Sum of back staff readings-

Sum of front staff readings.

Note: This simple method doesn’t allow to determine errors. It’s better to take measurements from A point to B point

and back to A point. In this case it is possible to compute locking error.

6.2. THE MEASUREMENT OF HORIZONTAL ANGLE

Horizontal circle digitizing is made clockwise in every 10˚ (360˚).

Scale minimun value of limb 1º.

1) Use the plumb for accurate setting of the instrument over the point.

2) Point at A point and rotate the limb (8) till the overlapping of index with 0˚ (Pic.15).

3) Point at B point and take reading.

Example: 30˚ (Pic.16)
