SAFETY INFORMATION
• To avoid unnecessary damage to the balance, please pay attention to the
following tips.
• Please do not use this balance in dangerous area.
• Only the trained technicians could operate this balance.
• Please turn off the power of the balance before connect it or disconnect
it with other facilities.
• If the environment requires a higher safety standard, please follow the
relevant installation instructions.
• Excessive electromagnetic interference will make the displayed value
in this balance change. Once the interference is dismissed, the balance
could operate in normal way.
• Please avoid any liquid on the surface of the balance. A piece of lightly
damp cloth is allowed to wipe the balance.
INSTALLATION
• Please make sure the local voltage is in line with the rated voltage on the
name board.
• Please pay special attention when use RS-232 as the pins location might
be incompatible with our facilities. Please check the pins locations before
the connection and turn off the connection of different configuration.
• If the facility or the power cord has apparent damage, please turn off

7
the power, put it or them in a safe place and do not use it or them before
they are fixed.
• This balance could only be connected to our accessories or optional
fittings. We are not responsible for any modification the operator makes
to our balance, including using the facilities and cable which are not
supplied by us. However, we are always ready to offer the operation
norms information.
• Please do not open the balance. If the guarantee lable is damaged, our
quality guarantee will automatically cease being effective.
• If the balance does not work well, please contact your local distributor or
our customer service center.
PREPARATORY BEFORE USING
Storage
This balance requires an environment which is free from excessive high or
low temperature, corrosive, vibration, air current and collision.
Unfolding the package
• Unfold the package and check if there is any outer damage of the balance.
• If there is outer damage, please refer to section routain maintenance
and troubleshooting.
• Please keep all the package for possible transportation in the future.
When pack the balance, please remove all the cables to avoid unnecessary
damage.

INSTALLATION OF THE BALANCE
Put it in a proper place, please avoid the following situations:
• Much heat and direct sunlight.
• Air currents and vibrations.
• Excessive moisture.
Usage Conditions
Please do not lay the balance in a quite damp palce for a long time. If the
balance is transferred from a lower temperature environment to a higher
temperature environment, please lay it there with power off foraround 2 hours.
Installation sequence
• Assemble the parts in the
indicated order.

3. Beaker
4. Convex holder (concave holder)
1. Put the bracket on the balance and adjust it to the right angle.
2. Put the beaker support and beaker onto the bracket in proper sequence.
3. Fill the beaker 5mm from the rim of it.
4. Test the temperature of liquid with thermometer.
5. Choose the right holder and hang it on the holder.
Connect the Power Adaptor
Only the power adaptor offered by us is allowed.

Preheat Time
To assure the measure accuracy, the balance must be preheated for 30
minutes before normal operation.
Adjust the Level Gauge
Purpose:
• Adjust the level gauge of the balance, the level
gauge needs to be adjusted once its place is
changed. The two front bottom bolts are used
to adjust the level gauge.
• Spin the two bolts as shown in the figure until
the bubble in the level gauge is in the center
of the circle.
• Normally, it needs to be adjusted repeatedly.

CALIBRATION
Procedure
1. Adjust the level gauge and preheat it for 30 minutes.
2. Press key.
3. Press key, the balance will read its full range (e.g.200), press
key repeateadly, it reads the calibration point within the range (e.g.200,
100, ...).
4. Choose one calibration point and place the right weight on the pan. Press
key, the balance starts calibration, “ACAL” displayed.
5. When the external calibration is 200.000g finished, the balance reads the
value of the weight on the pan (e.g.200).
BASIC WEIGHING (Tare function)
Procedure
1. Press the key , the balance will automatically proceed system
initialization and deduct the tare weight.
2. Place the container on the weighing pan.
3. Press the key.

4. Place the simple object in the container.
5. Print the weight value pressing the key.
SOLID / LIQUID DENSITY MEASUREMENT
Applied formula:
Sample density = Weight in the air / (Weight in the air – Weight in the liquid)
* Liquid density
Test solid material density
Because the buoyancy of the liquid density depends on the temperature,
temperature varies 1ºC, the density of distilled water will change 0.02%.
In order to modify the effect of temperature on density, please set the
temperature refer to function setting section:
