| Abstract: | Some amendments to the State Standard of GB 12897-91 are suggested. It is submited that the changeable compensation of the precise auto-leveller should be determined by stages,and that the auto-leveller Ni002 and some other instruments need not to determine the focusing movement error. The questions about the i-limit value for the instrument of first-order leveling and the like are discussed. |
