DESCRIPTIONDESCRIPTION
DESCRIPTION
DESCRIPTIONDESCRIPTION
The Ohaus Dial-O-Gram® Balance is a precision weighing instruments, designed
to provide years of service with virtually no maintenance. Dial-O-Gram® Balance
employs a two-pan design based on the classic Roberval balance principle. It has
the additional advantages of magnetic damping and integral dial for direct
weighing.
Two pan Balances of this type are commonly used for comparative weighing to
determine the difference in mass between two objects rather than their absolute
value, a built-in dial assembly of 100 grams capacity is usually sufficient for this
purpose. A 225g tare beam is standard on the 2060. The Model 2060 has a
weighing range of 100g and a readability of 0.1g. Maximum Balance capacity is
2kg/5lbs. The Platforms used on the Balance are 6" diameter stainless-steel.

Dial-O-Gram® Model 2060 Balances are shipped as follows:
• Completely assembled Balance
• Instruction manual
• Warranty card
Your new precision Balance has been packed in a carton specifically designed to
protect it during shipment. Follow these instructions and your Balance will be
operational in just a few minutes. Carefully unpack and verify that all items are
on hand.
1. Remove the Balance from the carton by pulling on the cardboard insert.
2. Remove cardboard inserts from Balance.
3. Remove the two round rubber beam retainers from between the base and
beam end loops. All packing material should be retained if you anticipate
any future shipment of the Balance.
INSTALLATIONINSTALLATION

INSTALLATIONINSTALLATION
Place the Balance on a reasonably flat, level surface away from sources of
vibration and drafts. On such a surface a very near balance should be attained
with the Dial at zero and Tare Poise against its stop at the left end of the beam.

Zeroing the BalanceZeroing the Balance
To set the Balance exactly at zero, adjust the knurled Zero Adjust Knob which is
located at the right end of the Beam. It is advisable to check the zero balance
periodically because foreign material may accumulate on the Platform or the
Beams. This can produce a slight change in the zero balance position. In addition,
whenever the Scale is moved, the zero balance
appreciable change in the inclination of the working surface will affect accuracy.
The base of each Balance is leveled on a surface plate at the factory and will rest
evenly on any perfectly flat surface. The Balance may rock slightly if the working
surface is not absolutely flat. This should be eliminated by shimming under the
base. Be sure to adjust the zero balance after leveling.

Before each weighing, be sure the Dial is set at zero, and the pointer is lined up
perfectly with the zero indicator.
The specimen to be weighed is placed on the left Platform of the Balance. The
Dial is then rotated until the Beam re-balances. Notice that magnetic damping has
been provided to bring the Beam to rest quickly. Because of the damping, the final
balance position must be achieved by turning the Dial knob slowly. With a little
practice, you will become proficient in learning exactly how fast to turn the Dial to
come to the balance position the first time. Since the capacity of the Balance far
exceeds the Dial capacity, the use of additional masses is necessary to take
advantage of the full capacity. Ohaus recommends Mass set No. 213-16 (1000g
x 1g).
For weights over 100 grams to capacity, it is easier to always set the Dial at 100
grams first. Then additional weights are placed on the right Platform of the
Balance until the total of these weights comes to within 100 grams. Then
rebalance by turning the Dial in a counter-clockwise direction from 100 grams to
its balanced position.
Reading the VernierReading the Vernier
Reading the Vernier
Reading the VernierReading the Vernier
Each graduation on the Dial has a value of 1 gram. A vernier adjacent to the Dial
divides these values to .1 gram increments. To read the vernier, read the lowest
gram value adjacent to the zero vernier graduation. Add to that the vernier
graduation at the vernier line which most closely lines up with any other Dial
graduations. The following illustration indicates a reading of 67.4 grams.

Use of the Tare PoiseUse of the Tare Poise
This model is equipped with a Tare Beam assembly. A patented Tare Poise can
be used to tare off containers which weigh less than 200 grams. With the container
on the left hand Platform, slide the Tare Poise to a position on the Tare Beam which
indicates approximate balance. Rotate the Poise in either direction to position it
precisely on the Tare Beam to counterbalance the container on the left hand
Platform. When not in use, the Tare Poise is to be moved all the way to the left
of the Tare Beam. The spring inside the tare poise should also be pushed to its
left most position in order to obtain zero balance.

A Clamp and Rod Support, Ohaus part number 183-00, is an accessory used to
elevate the Balance for suspending a specimen in water. The rod is inserted into
the 1/2 inch recess on the underside of the base. By means of a fine wire or thread,
the specimen is attached to the check pin which connects the platform loop to the
check rod. The procedure for weighing a suspended specimen is the same as that
for weighing an unknown mass on the Platform.
CARE AND MAINTENANCECARE AND MAINTENANCE
CARE AND MAINTENANCE
CARE AND MAINTENANCECARE AND MAINTENANCE
The following practices will assure that your Balance will give you years of
satisfactory and trouble-free service.
When the Balance is not in use, remove any mass or weights from the Platforms.
Move the Tare Poise from zero so that the Balance is not in equilibrium. This will
stop the Balance from oscillating and prevent unnecessary wear.
Use and store the Balance in places free of vibration.
bearings. The bearings in these Balances are high grade polished agate V-blocks
and the knife edges are hardened, precision-ground steel. This type of bearing
works most efficiently when clean and dry. Keep the Balance clean at all times,
being particularly careful not to let dirt accumulate in the vicinity of the bearings. If
the bearings should become dirty, try to clean them using an air syringe. The Model
106-00 Balance Cover is recommended to keep the Balance clean when not in use.

In general, most foreign matter may be easily removed by an air syringe. If the
damper vane still does not move freely, proceed as follows:
CAREFULLY CAREFULLY
1.
CAREFULLY turn the Balance on its side.

2. Remove the four (4) screws that mount the magnet case to the underside of
the base.
3. Remove the magnet case.
4. Clean the magnet faces by pressing a piece of adhesive-backed tape against
them.
5. Reinstall the magnet case.
