7. A horizontal collimation test is performed on an automatic level. With the instrument setup at point 1, the rod reading at A was 5.630 ft, and to B was 5.900 ft. After moving and leveling the instrument at point 2, the rod reading to A was determined to be 5.310 ft and to B 5.560 ft. As shown in the following figure, the distance between the points was 100 ft. What is the collimation error of the instrument, and the corrected reading to A from point 2? Rg.
