Digital Theodolite for measurement of vertical angle.
1)Taking out digital theodolite for box and fix it on tripod over required station.
2) Accurate centering and aapproximate leveling by leg adjustment is done..
3) Levelling the digital theodolite using foot screws by usual method i.e. plate level parallel to pair of foot screw and perpendicular position
4) Focusing of eyepiece and object glass is done using eyepiece and focusing screws.
5) Switch on the digital theodolite.
6) Direct the telescope toward the object of which angle is to be measured say A, bisect it. Clamp the instrument, accurate bisection is done by slow motion screw.one.
7) Press hold button, LCD gives required vertical angle from zenith point or horizantal plane as per setting of the instrument.
