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 angle. The instrument without temperature offset is always not to reach the standard of nation(GB/T10156-1997). 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 (Company standard: O.5"/℃). The red thick line A is a change curve for angle  I of level without temperature offset. The DSZ3 levels add a device of temperature offset, It can correct the change value of angle I when changing the temperature. The green thick line B is a change curve for angle I after offset, the instrument can be good work in the mal-conditions of larger tempe rature change, especially apply to transformation observation at a longtime.
