Temporary Adjustment of an IOP Level |
Temporary adjustment of a tilting level requires the same operations as in case of a dumpy level except the operations involved in leveling. During leveling, first the IOP instrument is leveled roughly with the leveling screws till the circular bubble is in the centre. Then, the bubble of the level tube is brought to the centre by using the tilting screw. In case of IOP level, the bubble is required to be leveled using tilting screw before each reading is taken. |
