V. Installation
Choosing the installation location
When analytical balances are used in routine lab or industrial
measurement environments, the weighing speed will be much
quicker, and the results more accurate. The location should meet the
following conditions:
1. Work room should be clean and dry
2. Balance should be placed on a solid, stable, plain flat surface
3. Avoid locations in which the balance could be exposed to any of the
following:

9
a. Airflow from air conditioners, fans, doors, or windows
b. Vibrations from surrounding or nearby equipment
c. Direct sunlight or radiation
4. Do not use the balance anywhere exposed to explosive,
combustible, or corrosive gases.
5. Do not use the balance in areas with high humidity or high levels of
dust
6. When moving from a cooler to a warmer place, the accuracy and
reliability of the scale will be influenced by the moisture
condensation inside the balance. In order to eliminate this
influence, it is best to leave the scale unplugged in its new location
for at least two hours before next use.
7. Keep the balance clean.
8. Do not leave material on the balance when not in use.
Unpacking and inspection
Check that all of the items indicated below are included in the package
and that nothing has been damaged:
·Balance
·Pan
·Power Cable
·External Calibration weight
·Manual
In case the balance or any component is damaged during transport,
tell your transportation agent immediately in order to process claims
within the proper time frame.

VI. Using the Balance
Level adjustment
Once the balance is placed at its location, check the bubble level; if
bubble is not well-centered, turn the adjustable feet so the bubble
moves to the center and the balance is properly leveled.
Start
1. Connect the balance to the power supply and press ON key on the
panel. Wait 30 minutes after powering on for best performance.
2. After warming up, calibrate the balance.
3. After calibration, the balance will enter weighing mode
4. To turn the balance off, press the OFF key on the panel and the
display will shut off. If the balance will be unused for an extended
period of time, disconnect it from the power supply.
Calibration
1. Press EXT CAL key; the value of the necessary weight will flash on
display
2. Put the calibration weight on the pan. Wait until the value of the
calibration weight stops flashing and is fixed on the display (e.g.
100.0000 g, 200.0000g, etc., depending on the model)
3. Remove the weight from the pan
4. The balance will enter weighing mode and will display 0.0000g

11
Note: Each balance includes the necessary weight to complete
external calibration
Tare function
1. Put the receptacle on the weighing pan; its weight will be displayed
2. Press “→T←” or “→0←” key and the reading on the display will
automatically be set to 0.0000g; tare is complete
3. If the receptacle is removed from the pan, the corresponding
weight, with negative value will be displayed
4. Press the “→T←” or “→0←” key again and the value on display
will be set to zero again
Weighing unit selection
Press UNIT key to select the desired weighing unit from g, lb, ct, oz, gn,
ozt, dwt, dr, MM, tl.j, tl.T, tl.H, tola
Counting
1. Press “PCS” to enter the piece counting mode
2. Prepare the sample, for example, prepare 10pcs samples and put
them on the pan gently
3. Press 10, and until the display shows 10pcs. Then remove the
samples gently. And it can work
4. Press to get back

VII. Maintenance and Cleaning
To get the best results and for product longevity, be sure to follow the
suggestions below.
Note: All of the suggestions and guidelines mentioned below and
throughout this manual will only be effective with continuous and
careful maintenance of the equipment
·Follow all processes outlined in the manual
·Make the manual available to all users of the equipment
·Prevent the balance from any sudden movements or falls, as well as
from direct sunlight or air flow. The balance is a precision instrument
and must be handled carefully.
·Balance must be plugged into a grounded electrical outlet and the
socket should be easily accessible to unplug in case of emergency
·Never unplug the balance by pulling on the wire, do so from the base
·Never use the balance in a wedged-in location, such as a shelf
·Never use other objects such as pens, pencils, etc. to press the
buttons on the control panel; use only your fingers.
·Never place anything on the pan heavier than the maximum capacity
of the balance, or the sensor could be damaged
·Do not submerge the balance, nor spill any liquids on it
·If any liquid does come into contact with the electrical parts of the
balance, immediately disconnect it and send it in for service to be

13
checked and adjusted if necessary
·Always use only original components and supplies. Other devices
and parts may appear similar, but can damage the equipment.
Cleaning
·Never use scourers or substances that can grate to clean metallic
parts. This include, but is not limited to, stainless steel, aluminum,
coatings, etc.. These can damage the balance and lead to early
erosion of effectiveness of the balance.
·Use a lint-free cloth, dampened with soapy water, that does not
contain any abrasive surfaces, nor corrosive materials
