Checking Level Accuracy
To check level accuracy of your Rugby, place the unit on a flat, level
surface or tripod approximately 100 feet (30 meters) from a wall.
Checking the X-Axis
Align the X-axis so that it is square to the wall. Allow the unit to self-level
completely (approximately one minute after the unit begins to rotate),
and then, using your Rod-Eye receiver, mark the position of the beam
(Position 1).
Rotate the Rugby 180°, allow it to self-level and then mark the opposite
side of the X-axis (Position 2).
Mark the position half-way between the two marks. The X-axis is within
its accuracy specification if the two marks are within ± 1/16” (± 1.5 mm)
from center.
