Q2 (a) (b) In a two peg test of an automatic level, the following readings were taken: (i) Instrument at B, midway between A and C where AB=BC Staff reading on A = 1.726 Staff reading on C = 1.262 (ii) Instrument at D where CD= AB/10 Staff reading on A = 2.245 Staff reading on C = 1.745 Determine whether the instrument is in adjustment? (5 marks) The following consecutive readings in meter were taken with an automatic level: (0.795, 1.855, 3.190, 3.015, 0.655, 0.625, 0.955, 0.255, 1.635, 0.860, 2.375). The level was shifted (moved) after the fourth and eight readings. The first reading was taken on a benchmark whose Reduce Level (R.L) is 550.605 meters. Create a page of a level book and enter the readings. Calculate the reduced levels of the stations by the Rise and Fall Method and apply arithmetical checks. Note: Use Appendix 1 to answer this question.
