Check the mounting surface and the abutment surface of
the scale for dust or dirt. Check if the mounting surface and
Datum surface are free from dust or dirt. If not, wipe the
surfaces with gauze moistened with alcohol.

Insert the scale between the scale clamp and the mounting
surface while pressing the scale lightly against the reference
abutment surface (Note). Tighten alternately screws A and
B of the scale clamp shown in the figure, gradually.

Note
When pressing the scale against the reference surface,
lightly press two points on the edge of the scale surface
opposite the reference surface with your fingers with a force
of less than 9.8 N=1 kgf as shown in Figure 1 below. If the
middle part of the scale is pressed with a force of
4.9 N (0.5 kgf) or more, as shown in 2 below or if the scale is
installed with deformation, the specified accuracy cannot be
achieved.
(This also applies to the following procedures. If it appears
that the scale has been bent with force, loosen the scale
clamp and mount it again properly.)

Leave the scale in this condition for over one hour until the
scale temperature stabilizes.

Fix the remaining scale clamps by alternately tightening
the screws.
