AIM: Check and note down the control lights using dumpy level

 Requirements:  dumpy level setup, area to be controlled

 Procedure: 1.  fix the tripod on a surface

2.  secondly Mount telescope on the tripod and check the level of the tripod

3.  check the level on the tripod there in a small circular Box with a bubble inside it should be at the centre of the

4.  then set the level of the telescope by putting the IPS in the centre of one of the two spinners or screws

5.  spin both the screws at the same time at the inward or outward

6.  when the level gets corrected then spend the telescope in 90 degree in short in between the next two screws

7.  now adjust the third screw and check the  level

8. if the level is correct then spend the telescope now start taking the reading

9. set the staff on the surface roughly 10 metres from the dumpy telescope

10. the reading of the staff seen through the telescope and men down upper middle and lower readings

11. next turn the  telescope to one side and more the staff as well

12. then measure the distance between the telescope and the staff distance using measuring tape

13. move the staff to one side and adjust the staff height such that middle is the same on that of the last

14. note down the upper and lower measure distance  again and measure it with a measuring tape
