When carrying out the permanent adjustments of a dumpy level by two-peg method, the following observation were made. Instrument at E midway between C and D, 100 m apart. Reading at point C = 2.000 m Reading at point D = 3.000 m Instrument at F in line of CD such that CF = 120 m and DF = 20 m. Reading at point C = 1.500 m Reading at point D = 2.750 m Check whether the instrument needs permanent adjustments or not, and whether the line of sight is inclined upwards. What should be the correct reading at C if the instrument is to be adjusted?
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?
