Check

a. Set the instrument on the tripod and level it carefully. 

b. Sight the cross-hair on a well-defined point A on the wall at

    a distance of at least 50 meters(160ft).

c. Next swing the telescope and check whether the point travels

    along the length of the vertical cross hair.

d. if the point appears to move continuously on the vertical hair

    (see fig.1), the vertical cross-hair lies in a plane perpendicular

    to the horizontal axis(adjustment is not required).

e. However if the point appears to be displayed from the vertical

    cross-hair(see fig.2), adjustment is required in the reticule 

    plate.
