A differential leveling circuit began on BM Rock (elevation 243.897 m) and closed on BM Manhole (elevation 240.100 m).The plus sight and minus sight distances were kept approximately equal. Readings (in meters) listed in the order taken are 0.288 (+S) on BM Rock, 0.987 (-S) and 0.305 (+S) on TP1, 1.405 (-S) and 0.596 (+S) on BM 1, 1.605 (-S) and 0.661 (+S) on BM2, and 1.992 (-S) and 1.056 (+S) on TP2, and 0.704 (-S) on BM Manhole. Prepare, check and adjust the notes.
