B. PROCEDURE 1. Establish corners of the designated field and mark these corners as stations A, B, C, D, and E with flaglets. 2. Set up and level the Engineer's Transit at station A. 3. Unlock the needle lifter of the compass box to enable movement of the compass needle. 4. With the telescope in normal position, sight station A then lock the upper and lower clamps to prevent unnecessary movement of the upper plate. When the needle becomes stationary, read the north end of the needle to determine the bearing of line AB. Record the obtained data in the accompanying table. - The telescope is in normal position when the eye piece of the telescope is in the south end of the compass needle or when the eye piece is above vernier A. -In reading bearings, the north end of the needle is the ane without the attached copper wire. 5. Transfer to the next station and repeat steps b, c, and d for bearings of lines BC, CD, DE, and EA. Record each obtained data in the accompanying table. 6. Measure the lengths of lines AB, BC, CD, DE, EA. Record the obtained distances in the accompanying table. dha Ba da dos
