1. TWO-PEG TEST. In the two-peg test of dumpy level, the following observations are taken: ROD READING INSTRUMENT SET UP NEAR M INSTRUMENT SET UP NEAR P 1.563 m On Point A On Point B i0.296 m 0.910 2.140 Point M is equidistant from both A and B, while P is 2,50 m away from A along the extension of line AB and 79. 27 m from B. Requirements: a. Determine the true difference in elevation between points A & B. b. Check if the line of sight is in adjustment.

1. TWO-PEG TEST. In the two-peg test of dumpy level, the following observations are taken: ROD READING INSTRUMENT SET UP INSTRUMENT SET UP NEAR P NEAR M On Point A On Point B i0.296 m 1.563 m 0.910 2. 140 Point M is equidistant from both A and B, while P is 2,50 m away from A along the extension of line AB and 79. 27 m from B. Requirements: a. Determine the true difference in elevation between points A & B. b. Check if the line of sight is in adjustment. 14 c. If the instrument needs to be adjusted, determine the following: "false" difference in elevation, inclination of the line of sight, and the error on the reading on the far rod. d. With the level still set up at P, determine the rod reading on B to which the line of sight should be adjusted. e. Perform the customary check. Fig. 16-3. Tw0-peg test. -Leveling Rod Loveling. Rod c=1.563 m d 2.140 b=0.910m a=0296m Ground Surface La (2.50 m) (76.77 m) (79.27 m)
