I) Procedure for measurement of horizontal angle with digital theodolite:
1) Taking out digital theodolite for box and fix it on tripod over required station.
2) Approximate leveling by leg adjustment and centering by judgment .
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 diaphragm and object using eyepiece and focusing screws,
5) Switch on the digital theodolite.
6) Seleclt the left or right direction mode by press button L/R
7) Direct the telescope towards initial object, bisect it, clamp the theodolite using horizontal clamp screw, make accurate bisection by using slow motion screw.
8) Press the button for zero reading,
9) Unclamp the clamp screw and bisect the final object, clamp it by clamping the clamp screw. Accurate bisection by the slow motion screw.
10) Press the hold button, LCD gives required horizontal angle between two point
11) The process may be repeated for required number of times to get mean reading.
b) Procedure for measurement of vertical angle with digital theodolite:
1) Taking out digital theodolite for box and fix it on tripod over required station.
2) Approximate leveling by leg adjustment and centering by judgment.
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 diaphragm and object using eyepiece and focusing screws,
5) Switch on the digital theodolite.
6) Direct the telescope toward A, bisect it. Clamp the instrument, accurate bisection by slow motion screw.
7) Press hold button, LCD gives required vertical angle from zenith point.
8) Similarly bisect and take the reading at B.
9) Difference of two angle gives required vertical angle AOB
