We know that compensator is made up of metal material and glass material, the temperature can affect these materials results in slight changes of compensator, then causes change of i. The instrument without temperature offset is always very large. In the diagram, the green area where between the red lines is a acceptable area when the compensator is changed along with the temperature's change (FOIF standard: ±0.5"/℃). The red thick line A is a change curve for i of level without temperature offset. Our DS03 precision level add a device of temperature offset, it can correct the change value of i when changing the temperature. The green thick line B is a change curve for i after offset, the instrument can be good work in the mal-conditions of large temperature change, especially apply to transformation observation at a long time.
