A horizontal collimation test is performed on an automatic level following the procedures described in Section 4.15.5. With the instrument setup at point 1, the rodreading at A was 3.886 ft, and to B it was 3.907 ft. After moving and leveling the instrument at point 2, the rod reading to A was 4.094 ft and to B was 4.107 ft. What isthe collimation error of the instrument and the corrected reading to A from point 2?
