12.5 Check and adjust optical plummet
Adjustment
is
required to make the line
of
sight
of
optical plummet telescope coincide with the vertical
axis ( as otherwise the vertical axis will not be in the
true vertical when the instrument
is
optically plumbed.)
Check
a. Coincide the center point with the center mark
of
optical plummet telescope by adjusting optical
plummet.
b. Revolve the instrument 1800
or
200g around the vertical axis
and check the center mark.
If
the point
is
properly centered in
the center.mark, adjustment
is
not required. Otherwise, adjust
in
the following manner:
Adjustment

Unscrew the adjustment section cover
