HEAVY DUTY
SOLUTION BALANCE
Instruction Manual
INTRODUCTION
This manual contains installation, operation and maintenance instructions for the
Ohaus Heavy Duty Solution Balance, Model 1119D. To ensure proper operation of
the Balance, please read this manual completely.
DESCRIPTION
The Model 1119D Heavy Duty Solution Balance is a dual beam mechanical balance
with a maximum capacity of 20 kilograms and a readability of 1 gram. A dual-faced
Indicator Plate allows front and rear weighing. The base and beam are constructed
of cast aluminum and finished with a durable epoxy powder coating which is
resistant to commonly used acids. Many other components including the large
platform are made of stainless steel for corrosion resistance. A large lockable tare
allows for balancing of containers up to 2270 grams (5 Lbs). Fine balancing may be
accomplished using the small spring loaded tare poise. Magnetic damping speeds
up the weighing process. Readings up to 1100 grams may be taken directly off the
two beams and the slotted mass set provided extends the weighing capacity to 20
kilograms.
UNPACKING AND SET-UP
1. Place the opened carton with the Beam Pointer facing toward the right.
2. Remove the corrugated liners from the front and rear of the carton. Remove
the Scale Plate from the rear liner and set it aside. Remove the corrugated
box, that contains the Slotted Masses, from the left end of the carton and set it
aside.
3. Grasp the Balance at both ends and lift it from the carton.
4. Remove the corrugated liner (that protects the Base) and the wooden wedge
from under the Scale Plate support.
5. Place the Balance on a bench or other level surface.
6. Remove the wire from the Mass Hanger Assembly, the Poises, and the left end
of the Beam. Remove the wooden beam end block.

UNPACKING AND SET-UP (Cont.)
7. Place the Scale Plate on the four vertical Support Posts, with the solid weld
stud resting on the left front Post (with the two Lock Nuts). Hook the mass
Hanger Assembly on the Ring that is located at the right end of the Beam.
8. Unpack the Slotted Masses from the corrugated box and place them on the
Mass Rack.
USING THE BALANCE (ZEROING)
1. Move all four Poises to their ZERO positions at
the extreme left end of travel. The Rear Poise is
equipped with a pin that will position it
accurately in the notches.
2. If the Balance does not come to rest exactly at
zero, it can be rebalanced by using the two
knurled, brass Adjustment Nuts of the Balance
Compensator Assembly. When correct balance
has been restored, be sure to lock the Balance
Nuts against each other to prevent movement.

WEIGHING
Net Weight can be determined rapidly by following
these steps:
1. Counterbalance the EMPTY container with the
two Tare Poises. Loosen the Thumb Screw of
the larger Tare Poise and move both Poises to
the right. The larger Tare Poise is used for
COARSE balancing and then is locked with the
thumb screw. The smaller Tare Poise is used
for FINE balancing. It is spring-loaded to protect
against accidental movement.
Tare Poise
2. Place the specimen as near the center of the Scale Plate as possible.
3. Move the Rear Poise to the right until it is in the first notch that will cause the
Beam to DROP below the Balance Indicator at the pointer end of the beam.
Move it to the left one notch and the Beam will RISE.
4. Move the Front Poise to the right until balance is obtained.
5. Read the weight of the specimen directly by adding the values indicated by
the Poises.
6. If the Rear Poise can be moved to the extreme right notch but it does not
cause the Beam to DROP, return both the Front and Rear Poises to ZERO
and add Slotted Attachment Masses to the Mass Hanger Assembly. Add
sufficient masses to cause the Beam to DROP below the Balance Indicator
at the pointer end of the Beam. Remove the smallest (lightest) mass and
follow Steps 3, 4 and 5. Add the total value of the Attachment Masses on
the Mass Hanger Assembly to the values indicated by the positions of the
two poises to obtain weight of the specimen.

CARE AND MAINTENANCE
The following practices will ensure that your Heavy Duty Solution Balance will give
years of satisfactory and trouble-free service.
1. When not in use, remove any load from the Scale Plate and place the Slotted
Masses on the Mass Rack. Slide one of the Poises away from ZERO, so that
the Balance is not in equilibrium. This will stop the Balance from oscillating
and prevent unnecessary wear.
2. Use and store the Balance in places that are free from vibration, which can
cause unnecessary wear.
3. Keep the Balance clean at all times, being particularly careful to not let dirt
accumulate in the vicinity of the bearings. Never use oil, or any lubricant, on
the knives or bearings. Lubrication will reduce the readability and accuracy of
the Balance.
4. Occasionally, it will be necessary to clean accumulated debris from the Magnet
Faces in the base of the Trig Loop Post Assembly. Insert a piece of adhesive-
backed tape into the Magnet slot that the aluminum Damper Vane enters.
Press the tape against the Magnet Face with a ruler or a similar thin strip. Dirt
or magnetic particles will adhere to the tape when it is removed and the
Damper Vane will be able to oscillate freely.
