reliable. It provides a high level of operating convenience and response
sensitivity to facilitate determination of the weight of your samples. U.S.
Solid’s dedicated customer service staff are available to answer any
inquiries regarding applications and accessories.
Please read the manual completely and follow the usage instructions
before installation and operation as this will help you to make full use of
the functions and performance of the USS-DBS83 Analytical Balance.
1.1 Safety Precautions
The U.S. Solid USS-DBS83 Analytical Balance qualifies as state-of-the-art
technology and complies with all recognized safety rules. Improper use
or handling, however, can result in damage and/or injury. Please follow
the precautions below to ensure safe and trouble-free operation of your
balance.
•The balance has a 3-pin power socket equipped with a
ground terminal. To prevent electric shock and to maintain

2
stability in operation of the balance, be sure to ground the balance.
•Avoid getting the balance wet as it is not water resistant. Any leakage
of liquid into the balance may damage the balance or cause an electric
shock to the user.
•Use a power source (voltage, frequency, outlet type)
adapted to the specification of the balance. If excessive
voltage is used, the balance may overheat and be damaged or cause a
fire.
•Operate the balance on a stable, rigid and flat table.
•Handle the balance carefully. It is a precision device,
subjecting it to impact may result in a malfunction.
•If the device is not be used for a long period of time, the power
should be turned off and disconnect the power cable.
•Do not disassemble, remodel or repair this product or accessories.

3.2 Selecting the Location
Measurement performance of your balance depends largely on the
surrounding environments.
Please follow these guidelines to make sure the proper environmental
conditions are met:
•Select a firm, horizontal location that is free from vibrations.
•Make sure that the ambient temperature is between 5°C and 30°C,
the relative humidity is around 50% and that non-condensing conditions
are met.
•Avoid direct sunlight and ensure that there are not any excessive
temperature fluctuations.
•Ensure the balance is places a sufficient distance from heat-sensitive
materials in the vicinity of the instrument.
•Avoid the effects of air currents from air conditioners, ventilators,
open doors, or windows.
•Keep away from objects or equipment that are magnetic or capable
of generating magnetic fields.
•Surroundings should be as free from dust as possible.

3.3 Installing Components
1. Place the balance main body
on the installing location.
2. Push the side glass door open.
3. Gently attach the pan on the
center axis of the weighing
chamber.
4. Push the side glass door close.
3.4 Leveling the Balance
Accurate horizontal positioning necessary for repeatable measurements
and exact results. To compensate for small irregularities or tilts at this
location, the instrument needs to be leveled.
Adjust the leveling feet of the analytical balance until the air bubble in
the indicator is centered. The level indicator is located under the cover
towards the rear of the analytical balance.

3.5 Connecting the Power
Warning:
•To prevent electric shock, be sure to use the 3-pin power cord with
equipment grounding connector.
•Check to make sure the voltage indicated on the analytical balance
data label matches the local line voltage. Do not connect the balance to
the power source if it does not match.
Connecting a power cable:
a. Insert the female end of the power cord into the power inlet located
at the rear of the main unit.
b. Plug the male end of the power cord into the outlet.
Note:
To obtain accurate results, the analytical balance must be warmed up for
at least one hour each time it is connected to an AC power source or
after a power outage of more than 30 minutes.
Only after this length of time will the balance reach the required
operating temperature.

Settings
4.1 Display Speed
If the operating environment meets the requirements, the display speed
of the balance can be adjusted to reduce the time required for the
balance to stabilize, thereby improving work efficiency.

Depending on the environment in which the instrument is used,
carefully select the display speed to avoid instability that might be
caused by excessive speed.
1. Press the “SET”button several times in succession until the “SPEED”is
displayed.
2. Press “TARE”to enter the selection of display speed mode.
3. Press “UNIT”to select required speed and confirm by pressing “TARE”.

4.2 Stability
According to different operating environments, the balance is kept in a
relatively stable state by adjusting its stability.
It is recommended that the balance be adjusted appropriately in an
environment that guarantees its normal operation.

4.3 Restore Factory Defaults
If the balance is improperly set or operated, all settings can be restored
to factory defaults, which will ensure that the balance is suitable for
most operating habits and environments. When the balance is found to
be abnormal and unstable, the stability of the balance can also be
adjusted by restoring the factory settings.
1. Press the “SET”button several times in succession until the
“DEFAULT”is displayed.
2. Press “TARE”to confirm and an audible signal will sound.
3. Then it will back to the splash screen, the factory defaults have been
restored.
* The setting is only applicable to situations where settings are confusing
due to incorrect operation. Factory defaults should NOT be performed
frequently.

15
Calibration
Calibration is a necessary step to assure the analytical balance will
accurately weigh the sample.
Perform calibration operations in the following situations:
•Changes in the location of use (including moving in the same room).
•Changes in ambient conditions.
•Prior to each use.
The balance must be fully warmed up for one hour to stabilize the
weighing before calibration.
Procedure:
1. Press “TARE”to zero the balance in the weighing state.
2. Press the “CAL”button and the “CAL-200”flashing displayed.
3. Place the 200g calibration weight on the weighing pan.
4. Then “200.0000g”will be displayed. External calibration is completed.

Weighing and Applications
6.1 Weighing
Note: Please warm up for at least one hour and calibrate before using.
1. Press “TARE”to zero the balance in the no-load state.
2. Open the glass door of the weighing chamber and place the weighing
sample on the weighing pan, then close the glass door.
3. Wait for the display to stabilize. The appearance of the stability mark
indicates a stable state.
4. Read the value displayed.
Weighing a sample that needs to be in a container:
1. Open the glass door of the weighing chamber and place the weighing
container on the weighing pan, then close the glass door again.
2. Wait for the display to stabilize.The appearance of the stability mark
indicates a stable state. Then press “TARE”to tare, and the displayed
value will return to zero.
3. Open the glass door and place the sample(s) to be weighed in the
weighing container, then close the glass door.
4. After the display stabilizes, read the value displayed.

6.2 Unit of Weight
The USS-DBS83 Analytical Balance has multiple sets of weight units. The
unit selection function can be used to meet the unit requirements in
various usage situations.
1. Press the “UNIT”button to select required unit.
2. Press “TARE”to zero the displayed value and begin to weighing the
sample.
To avoid the deviation of the weighing record caused by unit misreading,
please ensure that the selected unit is the one required.

6.3 Counting Function
The U.S. Solid USS-DBS83 Analytical Balance has a built-in counting
function that meets various industrial counting requirements, especially
the counting function for small components.
To ensure the accuracy of the counting function for small components, it
is necessary to ensure that the weight of all samples is consistent, and
that the weight of a single object is ≥0.5mg.
1. Press the “SET”button several times in succession until the “COU”is
displayed.
2. Press “TARE”to enter the counting function, “COU 5PCS”will be
displayed.
3. Press “UNIT”to select the quantity and put the corresponding
quantity of samples. Press “TARE”to confirm and “COU ---PCS”will be
