To adjust a dumpy level by peg method of adjustment, two points A and B were set up. With the instru- ment at point A, the rod reading at A was 1.623m and the foresight at B was 2.875m. The level is transferred at Band the backsight at B was 1.622m while the rod reading at A was 0.362m. Find the true difference in elevation between A and B. What is the error in the line of sight? Determine the correct rod reading at A that will give the level line of sight with the instrument still at point B.
