8.2 Leveling on the X-axis bed (table bed)

※ Setting the reference point for the X-axis level
(1) Place the level in the center of the table and read one-end gradation of the water
bubble of the level.
(2) Turn the level by 180 degrees and read the gradation in the same direction.
(3) With a plain screwdriver, adjust the reference point screw to set the level to an
intermediate gradation between initial gradation (before rotation) and gradation after
180 degrees of rotation.
(4) Repeat steps 1) through 3) above until rotation in either direction comes up with the
same result.
※ Reading the level (example)
Negative (-)
(Right end of the water bubble + Left end) ÷2＝
Level gradations (-50 + -40) ÷2＝- 45
▪ The level in the picture is 45μ/m higher at the
left side.
▪ In most cases, reading either one-end gradation is much easier than reading both for the
level setting or leveling work.
