- 6. 1. Simple Levelling : This method enables us to determine the difference in level between two points by placing the instrument approximately mid way between the two stations , while taking the readings, the bubble remain in the center as usual. A R.L=100.00 2.200 B.S 2.700 F.S Staff reading at A = 2.200 Height of collimation = 100 + 2.200 = 102.200 Staff reading at B = 2.700 R.L of B = 102.20 - 2.700 = 99.500
