[ LEVELING A SURFACE ]
Leveling in one direction.
（１）

0-Cal Button.
（

）
Rotate the instrument 180° in the same location on the surface, and once the
display has stabilized press the 1/2-Cal Button.
（

）
Adjust the tilt of the surface to make the instrument's display read zero.
（
4
）
Rotate the instrument 180° again to confirm that the reading is zero and the
surface is level.
If it does not read zero after rotating, then repeat steps (1) ~ (4) above.
Note: If there is a large tilt in the roll direction (perpendicular to the measurement
axis) there will be some display error and it will be difficult to level the surface. In
this case, please also adjust the surface so that the roll direction is also level.
