TM 5-6675-329-13 & P
The Surveying Level NA2-80 is a survey instrument designed to make precise optical measurements in the field.
The precise measurement is vertical and is used to determine difference in elevation. It will perform satisfactorily if it is
carefully handled, maintained and operated as specified. While mounted on the tripod and temporarily not in use, the
Automatic Level NA-2 must be covered (use rain and dust cover indicated in Figure 1-1, item 5) to protect it from rain,
dust and physical damage. In a humid environment, the instrument must not be stored in its carrying case, or any closed
container for extended periods of time. Air must be allowed to circulate freely around it in order to prevent mildew or the
growth of fungus. (Refer to paragraph 1-3b).
