While carrying out the permanent adjustment of a dumpy level by two peg method, the following obervations were made:
Check whether the instrument needs adjustment or not and whether the line of collimation is inclined upwards or downwards. What should be the correct reading at C if the instrument is to be adjusted at F?
| Instrument At | Reading on C | Reading on D | Remark |
| E midpoint of CD | 2.000 | 3.000 |
CD = 100 m; CF = 120 m; DF = 20 m; |
| F | 1.500 | 2.75 |
