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
