In carrying out the permanent adjustments of a level by, the following observations were made: Instrument at peg (C) midway between points A and B, 100m apart. Readings at points A and B are 2.500m and 3.500m, respectively. Instrument at peg (D) in line of AB such that AD-120m and BD-20m, Readings at points A and B are 1.500m and 2.600m, respectively. Check whether the instrument needs permanent adjustment or not and whether the line of sight is inclined upward or downward. What should be the correct reading at (A and B) if the instrument is to be adjusted?

Ex-2-: In a levelling process the readings were recorded as following: (1.349, 1.723, 1.522, 1.634, 1.542, 1.773, 1.829 m). If the Level instrument was relocated after the fourth reading and the level of the fourth point was (30 m). Calculate the elevations of the other points and do check your calculations.
Reciprocal leveling gives the following readings in meters from a set up near A: on A, 1.110; on B, 0.887, 0.995, and 0.884. At the setup near B: on B, 1.549; on A, 1.673, 1.670, and 1.666. The elevation of A is 1045.343 m. Determine the misclosure of B. Express your answer to three decimal places and include appropriate units. Misclosure = Submit Part B elevB = μÁ Value Request Answer CHA Value Units Determine the elevation of B. Express your answer to three decimal places and include appropriate units. Units ? ?
Q2/ Complete the settlement table below and verify the correctness of the calculations. Then check the correctness of the work, bearing in mind that the length of the leveling line is 2,250 meters, bearing in mind that the required level of leveling is the third. Find the closing error and adjust the levels if necessary, suppose that the error equal for all points.

In the two peg-test methods of a dumpy level, the following observations were taken. Instrument set Instrument set up near A up near B Rod reading on A Rod reading 2.35 m 1.05 m on B 2.90 m 1.25 m [ Select ] Determine the error in the line of sight. [ Select ] If the line of sight is not in adjustment, determine the correct rod reading on A with the instrument still set up at В.
