II. PROCEDURE a. Mark off points on pavement with chalk about 150 to 200 meters apart and call these BM-1 and BM-2. The elevation of BM-2 is to be determined while the elevation of BM-1 is known or assumed. Also, imagine that there is an intervening deep ravine or wide river between these two points. b. Set up and level very carefully the instrument at a point (A) near BM-1. c. Take and record a series of three consecutive backsight rod readings on BM-1 and six consecutive foresight rod readings on BM-2. d. Move the instrument to point B (on the opposite side of the imaginary ravine and near BM-2, set up, and level the instrument carefully. e. From the new set up, take and record three consecutive foresight rod readings on BM-2 and six consecutive backsight rod readings on BM-1. f. Tabulate observed and computed values accordingly. INSTRUMENT SET UP NEAR BM-1 Station BS FS 1
