1. In the two peg-test of a dumpy level, the following observations were taken: ROD READING INSTRUMENT SET-UP INSTURMENT SET-UP NEAR NEAR A NEAR B On point A On point B 1.505m 0.938m 2.054m 1.449m a. Determine if the line of sight is in adjustment. b. If the line of sight is not in adjustment, determine the correct rod reading at A with the instrument still set-up near B. c. Determine the error in the line of sight for the net distance AB.
