Cautions:
(1)The vicinity of the hull unit (on the ship’s bottom) is too low and should be avoided, since the polarity of the measured value is reversed.
(2)When it is impossible to install the clinometer on the intersecting point of both rolling and pitching rotational axes, a special effort should be made to install it at place where the vertical distance to the intersecting point is minimum.
(3)The clinometer should be installed on the horizontal plane.
(4)Install the clinometer with the bow mark pointing in toward the ship’s bow.
