Check
①
Set the instrument on the tripod and carefully level it.
②
Sight the cross-hair on a well-defined point A on the wall at a distance of at least
50 meters. (160ft )
③
Next swing the telescope and check whether the point travels along the length of
the vertical cross-hair.
④
If the point appears to move continuously on the vertical hair, the vertical cross-hair
lies in a plane perpendicular to the horizontal axis.(adjustment is not required.)
●
Adjustment
①
Unscrew the cross-hair adjustment section cover by revolving it in the counterclockwise
direction, and take it off. This will expose four eyepiece section attachment screws.
②
Loosen all four attachment screws slightly with the accessory screw-driver. (while
taking note of the number of the revolutions) make vertical cross-hair coincide with A by
turning eyepiece and tighten the four attachment screws.
