（１）
For one direction (for example the X-direction,) follow the above procedure for
“Leveling in one direction.”
（２）
Repeat the procedure for the other direction (the Y-direction.)
（３）
When adjusting in one direction, it is possible that the perpendicular direction will
be affected and no longer level. It may be necessary to repeat steps (1), (2),
several times to bring the two axis into level.
When the reading is zero for the gauge placed in any position, the surface is level.
