18.
Check whether the measured values are conformed to the following standard.
ALL 72 spots: ±0.1mm
Over 51 spots: ±0.075mm
If the measured values are conformed to the standard, adjustment is not needed.
Proceed to the next section.
If the measured values are not conformed to the standard, proceed to the next step to
perform the table surface parallelism adjustment.
.
19.
Calculate the reference value for the table surface parallelism adjustment.
Regard a middle value of all of the measurement spots as reference spot.
In the following case, 0.30 [A] is highest and -0.20 [B] is lowest value. Therefore,
you can regard 0.10 [C] as a reference.
We will fix the abnormal gap until the sensor head indicate the reference value by
adjusting the adjustment screw around the spots which need adjustment.

Measuring point of right and left side edges are just confirm the value because no
adjustment screws into the both side edges. Adjust them by adjacent screw.
