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 ex-
treme 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 Ad-
justment 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.
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 unnec-
essary 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 accumu-
late 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.
