| Abstract: | This paper introduces the structures and basic working principles of digital levels and staff with code, such as ZEISS DINI 20 and TOPCON DL 102. According to analysing the results of the experiment which test the function of DINI 20's eompengator and DL 102's stall with code, as well as the experiment precision, the conclusion can be drawn that DINI 20 and DL 102 can be used in third-order and fourth-order leveling generally, in certain condition it can also be used in second-order leveling,In addition, some problems in surveying practice have been pointed out. |
