Description
Prismatic Compass :
It comprises a magnetic needle attached to a graduated circular ring made up of aluminum. The needle orients itself to the magnetic meridian if it is on the pivot. Object vane and eye slit are attached to the compass box and help in locating the line of sight.
It is a magnetic compass that measures the magnetic meridian. It is portable and hence convenient too. It can be either used in the palm or fixed on a tripod.
Object vane has thin vertical hair while eye slit has a vertical slit. A triangular prism is also attached below the eye slit to suit different sighting requirements with both horizontal and vertical faces convex.
The south end corresponds to 0° while the west end corresponds to 90° and so on. Thus, the north end is at 180° while the east end is at 270°.
Temporary or permanent adjustments are to be carried out for the compass as required. Centering, leveling, and focusing of the prism are temporary adjustments. The temporary adjustments are to be made every time the instrument is set.
