The pitch of a screw gauge is 0.5mm and there are 50 divisions on circular scale. When there is nothing between the two ends (studs) of screw gauge, 45th division of circular scale is coincide with screw guage, and in this situation zero of main scale is not visible. When a wire is place between the studs, the linear scale reads 2 divisions and 20th divisions of circular scale coincides with references line. For this situation mark the correct statement(s).

Answer:
To ensure accurate focusing
Explanation:
It's crucial to leave the focusing screw alone to achieve precise focusing.
Screws for focusing to direct the levelling staff. This screw is located next to the eyepiece in some levels whereas it is on the right side of the telescope in others.
By adjusting the eyepiece and the focusing screw, you can focus. The eyepiece is adjusted such that the diaphragm crosshairs are plainly visible. A white piece of paper is utilised to provide clear visibility of the cross hairs and eliminate parallax mistake.
To examine the clear picture of the objective or staff, the focusing screw is adjusted. When the crosshairs clearly divide the target or staff, focus is said to be achieved.
It's time to take the necessary places or points after finishing the aforementioned temporary changes. The telescope is turned such that it cuts over the staff or objective line. The levels are documented at various sites, and the values are chosen based on a recognised benchmark point in that region.
