OPERATING INSTRUCTIONS
A. Mounting:
A 2-1/2in diameter supporting ring provides a means to
hang the scale mechanism.
B. Adjustment:
Fill the plastic bucket to the spill holes with clear water. The
bucket spill holes are located so that slightly more than
1,000 cc. will be contained. Fill the bottom of the slot to
proper level to permit spillage at 1,000 cc. Hang this on the
scale hook until the scale pointer is vertical, reading 1.000
on the outer ring of the dial. The scale is now calibrated.
C. Determining the Specic Gravity of Dry Solids:
The innermost circle marked for determining the specic
gravity of dry solids is used for this purpose. A sample of
material for determination should be dry and preferably all
-10 mesh, +100 mesh. Hang the dry empty bucket on the
pulp density scale; then pour in the sample of dry material
until the pointer indicates 1,000g (1kg) on the outer circle of
the dial. At this point the bucket will contain one kilogram
of dry material. Dump the sample material onto a rolling
cloth or paper sheet. Fill the bucket about 1/3 with clear
water. Pour the sample slowly into the bucket, making sure
that all material is thoroughly wetted, and all air bubbles are
eliminated. After wetting, add clear water until the bucket
is lled to the overow level. Hang the bucket on the scale
and read the specic gravity of the dry solids directly on the
innermost circle of the dial.
D. Taking a Sample:
Fill the plastic bucket with pulp or liquid requiring mea-
surement. The liquid level should reach the spill holes in
the bucket. Any spill on the outside of the bucket should
be washed o. Hang the bucket on the scale and determine
the specic gravity or percent of solids.

E. Determining Specic Gravity of Pulp:
To obtain this measurement, hang the lled bucket on scale
and read directly on the outer white ring where pointer
stops.

OPERATING MANUAL

F. Determining Percent Solids:
Hang lled bucket on scale. Select the correct dial ring for
the specic gravity of dry solids of your material. For exam-
ple, the specic gravity dry solids of your material is 2.2 at
the center vertical column showing specic gravity of dry
solids, 2.2 is the outer red ring, you would read the percent
solids as being 44. At 2.6 specic gravity which is the next
inner ring, the percent solids is 39, for 2.8 specic gravity the
reading is 37.25%, at 3.2 specic gravity the reading is 35%,
at 3.6: 33%, 4.0: 32% and at 4.4 the reading is 31%.
G. Changing Dial Faces:
Should the dial on the scale not cover the dry solids specic
gravity range of your sample, any of the interchangeable
dial faces may be installed as follows:
1. Remove the scale, laying it at on a table.
2. Loosen the thumbscrews on the sides of the scale and
lift o 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 se-
lected dial in both hands with the split in the dial direct-
ly above the pointer. Depress the right side of the split
dial beneath the pointer, then rotate dial 270° clock-
wise. 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.
WARNING!
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.
Each scale is furnished with the #1 dial face having the following
specic gravity range of dry solids:
#1 2.2 2.6 2.8 3.2 3.6 4.0 4.4
Interchangeable Dial Faces are supplied with the scale as fol-
lows:
