STUDY OF THEODOLITE EXP:01 DATE: TRANSIT THEODOLITE:It consists of a telescope which can be revolved through a complete revolution about its horizontal axis in a vertical plane. PARTS:Leveling head, telescope, vertical circle, index frame, A frame lower plate, upper plate, level tubes, plumb bob LEVELING HEAD:The leveling head consists of two parallel triangular planes known as tribrach plates. The upper tribrach has three arms, each carrying a leveling screw. The lower tribrach has three arms each carrying a leveling screw. The lower tribrach plate or foot plate has a circular hole through which plumb bob may be suspended. TELESCOPE:The telescope is an integral part of the theodline and is mounted on a spindle known as horizontal axis or trunnion axis. In most of the transits, internal focusing telescope is used. VERTICAL CIRCLE:The vertical axis is a circular graduated arc attached to the trunnion axis of the telescope consequently the graduated arc rather with the telescope when the latter is turned about the horizontal axis. INDEX FRAME:- The index frame is a T-shaped frame consisting of a vertical leg known as clipping arm and a horizontal bar known as vernier arm of index corm. At the two extremities of the index arm are fitted two verniers to read the vertical circle.

STUDY OF THEODOLITE A FRAME:Two standards resembling the letter A are mounred on the upper plates. The trunnion axis of the telescope is supported on these. LOWER PLATE:The lower plate is attached to the outer spindle. The lower plate carries a horizontal circle at its leveled edge and is therefore also known as the scale plate. UPPER PLATE:- The upper plate or vernier plate is attached to the inner axis and carries two verniers with magnifiers at two extremities diametrically opposite. The upper plate supports the standards.
