VI. 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 eective with continuous and careful maintenance of the equip-
ment
• 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 fl w. 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 finger .
• Never place anything on the pan heavier than the maximum capacity of the bal-
ance, 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 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 eectiveness of the balance.
• -Use a lint-free cloth, dampened with soapy water, that does not contain any
abrasive surfaces, nor corrosive materials
ATTENTION!! If equipment is not properly
cleaned and cared for, technical service will be
unable to fix or epair issues.

V. 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 o, press the OFF key on the panel and the display will shut o. If the
balance will be unused for an extended period of time, disconnect it from the power supply.
Calibration
3. Remove the weight from the pan
4. The balance will enter weighing mode and will display 0.000g.
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 TARE key and the reading on the display will automatically be set to 0.000g; tare is
complete
3. If the receptacle is removed from the pan, the corresponding weight, with negative value
will be displayed.
4. Press the TARE 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, ct, oz, and lb
Piece counting function
1. Press the PCS button
2. Press the CAL button repeatedly to cycle through dierent counts. This function can be used
with counts of 10, 20, 50, 100, 150, 200, 250, or 500 pieces.
3. Put the corresponding number of pieces on the pan, press the PCS button to confi m.
4. Remove the pieces from the pan and the balance is ready to be used in piece counting
mode.
5. To return to weighing mode, simply press the PCS button again.
1. Press and hold down CAL key, when it shows ”CAL” on display, release the keys; then 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. 100.000 g, 200.000g, etc., depending on the model).

IV. Installation
Choosing the installation location
When analytical balances are used in routine lab or industrial measurement environ-
ments, 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 fl t surface
3. Avoid locations in which the balance could be exposed to any of the follow-
ing:
a. Airfl w 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 influen ed by the moisture condensation inside the balance.
In order to eliminate this influen e, it is best to leave the scale unplugged in
its new location for at least two hours before next use.
7. Avoid extreme temperatures or exposure to direct sunlight or air condition-
ers. Ideal working temperatures are between 5° C and 35° C (41°F and 95° F)
with tempature flu tuations of less than 1° C (1.8° F) per hour.
8. Keep the balance clean.
9. 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 noth-
ing has been damaged:
• Balance
•Pan
• Power Cable
• External Calibration weight
• Draft Shield Pieces
In case the balance or any component is damaged during transport, tell your transpor-
tation agent immediately in order to process claims within the proper time frame.
