Determining Specific Gravity of Pulp:
To obtain this measurement, hang the filled bucket on scale and read directly on
the outer white ring where pointer stops.
Determining Percent Solids:
Hang filled bucket on scale. Select the correct dial ring for the specific gravity of dry
solids of your material. For example, the specific gravity of dry solids of your
material is 2.2 at the center vertical column showing specific gravity of dry solids,
2.2 is the outer red ring, you would read the percent solids as being 44. At 2.6
specific gravity which is the next inner ring, the percent solids is 39, for 2.8 specific
gravity the reading is 37.25%, at 3.2 specific gravity the reading is 35%, at 3.6: 33%,
4.0: 32% and at 4.4 the reading is 31%
Changing Dial Faces:
Should the dial on the scale not cover the dry solids specific gravity range peculiar
to your operation, any of the interchangeable dial faces may be installed as
follows:
1.
Remove the scale, laying it flat on a table.
2.
Loosen the thumbscrews on the sides of the scale and lift off the clear cover
and retaining ring.
3.
Remove the two screws and washers near the center of the dial. Do not
remove or bend the pointer.
4.
With pointer pointing directly at your body, take the selected dial in both
hands with the split in the dial directly above the pointer. Depress the right
side of the split dial beneath the pointer, then rotate dial 270° clockwise. This
then places the dial beneath the pointer. turn dial to correct position lining-
up with the two screw holes and the four positioning marks on the outer rim
of the dial.
5.
Replace the two screws and washers. Replace the glass cover plate and
retaining ring, tighten thumbscrews.
CAUTION:
The scale has been factory set. Do not remove the back cover plate of
the scale or change any internal adjustment. The scale has been constructed for
trouble-free operation and will provide accurate measurement if the mechanism is
not altered. Pulp density scales are accurate to +/- 10 g.
