In the two-peg test of a dummy level, the following observations are taken. *INserted Photo* Point M is equidistance from both A and B, while P is 2.50m away from B along the extension of line AB and 90 meters from B. Requirements: Determine the true difference in elevation between point A and B. Answer: ____________ With the level still set up at P, determine the rod reading on A and B to which the line of sight should be adjusted. Answer: ____________
Situation 1: A two-peg test is used to check whether the ine of sight of the level is in perfect adjustment and the following rod readings are taken, with instrument set up near A, backsight on A is 1.623 m. and foresight reading on B is 2.875 m. With the instrument set up near B, backsight on B is 1.622 and a foresight on A is 0.362 m. a. Find the difference in elevation. b. What should be the correct rod reading on A to give a level line of sight with instrument still set up near B? c. What should be the correct rod reading on B to give a level line of sight with instrument still set up near A?
