IV. Installation
Choosing the installation location
When analytical balances are used in routine lab or industrial measure-
ment 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 at surface
3. Avoid locations in which the balance could be exposed to any of
the following:
a. Airow 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, combus-
tible, 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 inuenced by the moisture con-
densation inside the balance. In order to eliminate this inuence,
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
conditioners. Ideal working temperatures are between 5° C and
35° C (41°F and 95° F) with tempature uctuations 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 nothing 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 transportation agent immediately in order to process claims within
the proper time frame.

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
1. Press CAL key; the value of the necessary weight will ash on display
2. Put the calibration weight on the pan. Wait until the value of the calibration
weight stops ashing and is xed 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 0.000g or 0.0000g
Note: Each balance includes the necessary weight to complete external calibra-
tion
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 or 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 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 dierent 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
conrm.

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 through-
out this manual will only be eective with continuous and careful mainte-
nance 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 ow. 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 but-
tons on the control panel; use only your ngers.
• Never place anything on the pan heavier than the maximum capaci-
ty 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
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, coat-
ings, etc.. These can damage the balance and lead to early erosion
of eectiveness of the balance.
• -Use a lint-free cloth, dampened with soapy water, that does not con-
tain any abrasive surfaces, nor corrosive materials
ATTENTION!! If equipment is not properly
cleaned and cared for, technical service
will be unable to x or repair issues.
