Warning and safety use instructions
•To avoid damage of the balance, please read the operation manual carefully
•before use.
•Please do not use it in dangerous environment.
•Please cut off the electricity without use for more than one week.
•Please power off the balance when it connects with output device or before cut off the connection.
•Magnet or static interference will affect the accuracy of balance, when these
•interference removed, balance will recover to normal use.
Spare Parts
•The spare parts we used are the most compatible with the balance.
•Any revision to the balance or use the third party’s cable and other device, it’s end user’s
responsibility to check and correct the power and voltage.
•Please do not open the out case, if the safety label is damaged, warranty
•will not be guaranteed.

Overview
•LCD backlight display, easy and clear.
•Operator-friendly, direct weigh, directly read the weighing result.
•Highly smart, tare and back to zero within the whole weighing scope, overload
•display.
•Multi-mode choice: counting, percentage weigh, density weigh.
•RS-232C interface, easy to connect with printer and PC
Remarks
•Do not wash with water;
•Do not install the balance in places where is too hot or too wet, with vibration,、corrosion, strong
magnet or with the risk of explosion;
•Do not load excess samples (not over the max capacity
•If the balance is not used for a long time , please clean it up ,pack it by plastic bag with drier in ;
•Please pre-heat for 60 minutes before use the balance.
Preparation before Use
•Adjust level before use.
Use the air bubble and feet under the front to adjust the level until the bubble move to the centre
of the circle.
•Put the balance on the stable and flat table, not on shaking or vibrating plate, to make the balance
stable. (Recommend to use aseismic marble)
•Avoid to put balance in place with big temperature change or air flow, such as the place with direct
sunlight or cold air outlet.
•Please use the separate power socket to avoid the interruption by other device.
•Please do not put anything on the scale when power on the balance.
•Make balance adjust itself to the change of temperature.
When change the balance from lower temperature to higher temperature or reverse, please put
the balance in the new environment for about 2 hours, then pre-heat the balance , make it conform
with the new room temperature.

Density
By using this procedure user can measure the density value for solid or liquid so
that judge the sample desirable or not. (need to buy the optional density kits).
First measure the solid density in air, and then the density of the solid in a certain liquid ( the density of the
liquid must be known in advance)
