3.Precautions
To get the optimum performance from the balance and acquire accurate weighing data,
note the following:
3-1 Before Use
The maximum resolution of the precision balance is one million counts. Therefore, there are
tendencies to be influenced by temperature change, air pressure change, vibration and
drafts where the balance is placed.
Install the balance in an environment where the temperature and humidity are not
excessive. The best operating temperature is about 20°C / 68°F at about 50% relative
humidity.
Install the balance where it is not exposed to direct sunlight and it is not affected by heaters
or air conditioners.
Install the balance where it is free of dust.
Install the balance away from equipment that produces magnetic fields.
Install the balance in a stable place avoiding vibration and shock. Corners of rooms on the
first fl oor ar e best , as they ar e les s pr one to vi brat io n.
The w eighi ng tab le s houl d b e soli d a nd fr ee fr om vi br ati on, dr aft s an d as lev el as pos sibl e.
Level the balance by adjusting the leveling feet and confirm it using the bubble spirit level.
Ensure a stable power source when using the AC adapter.
Connect the AC adapter and warm up the balance for at least 30 minutes.
Cali brat e t he bal an ce per io dic ally for acc ura te wei gh ing .
When the balance is installed for the first time or has been moved, warm up the balance for
at least 6 hours to allow the balance to reach equilibrium with the ambient temperature, and
then perform calibration before use.
The meaning of IP-65 is "No ingress of dust. Projected against water jets".
If a powerful water jet is used or the balance is immersed in water, it may cause a damage
that is due to ingress of water.
Confirm that "the plug is inserted firmly into the jack" and "the terminal is covered using the
waterproof cover or the waterproof RS-232C cable (AX-KO2737-500JA)", when using the
balance.
Use the waterproof option cable AX-KO2737-500JA, when the RS-232C interface is used
with IP-65.
AX-KO2466-200, a st andard RS-232C cable, is not waterproof or dustproof.
Confirm that the weighing pan does not touch to rim.
Do not install the balance where flammable or corrosive gas is present.

Draft
Weighing Pan
Grounding
Shock
Discharge static electricity from the weighing material. When
weighing sample (plastics, insulator, etc.) could have a static
charge, the weighing value is influenced. Ground the balance, and
Eliminate the static electricity by AD-1683 as an accessory.
Or try to keep the ambient humidity above 45%RH at the room.
Or use the metal shield case.
Or wipe a charged material (plastic sample etc.) with the wet cloth.
This balance uses a strong magnet as part of the balance
assembly, so please use caution when weighing magnetic
materials such as iron. If there is a problem, use the underhook on
the bottom of the balance to suspend the material away f rom the
influence of the magnet.

material
Eliminate any temperature difference between the samp le and the
environment. When a sample is warmer (coole r) than the amb ient
temperature, the sample will be lighter (heavier) than the true

weight. This error is due to a rising (falling) draft around the
sample.
Make each weighing gently and quickly to avoid errors due to
changes in the environmental conditions.
Do not drop things upon the weighing pan, or place a sample on
the pan that is beyond the balance weighing capacity. Place the
sample in the center of the weighing pan.
Do not use a sharp instrument such as a pencil to p ress the ke ys.
Use your fing er only .
Press the RE-ZERO key before each weighing to prevent
possible err ors.
Cali brat e t he bal an ce per io dic ally so as to el i minat e p ossi ble err ors .
Take into consideration the affect of air buoyancy on a sample
when more accuracy is required.
Prevent foreign matter, such as powder, liquid and metal, from invading the area around
the weighing pan.
3-3 After Use
Use t he "b reez e br eak " for a pr eci sio n weig hi ng.
Avoid mechanical shock to the balance.
Do not disassemble the balance. Contact the local A&D dealer if the balance needs service
or repair.
Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth
that is moistened with warm water and a mild detergent.
12
Do not allow the balance to be immersed in wa ter. Even thou gh the ba lance comp lie s with
IP code, the balance will not withstand being completely immersed in water.
The weighing pan, pan support and draft gate can be removed to clean the ba lance. Clean
by spl as hi ng w it h w a ter .
3-4 Power Supply
Do not remove the AC adapter while the internal mass is in motion, for example, right
after the AC adapter is connected, or during calibration using the internal mass.
If the AC adapter is removed under the conditions described above, the internal mass
will be left unsecured, that may cause mechanical damage when the balance is
moved.
Before removing the AC adapter, press the ON:OFF key and confirm that zero is
displayed.
When the AC adapter is connected, the balance is in the standby mode if the standby
indicator is on. This is a normal state and does not harm the balance. For accurate
weighing, keep the AC adapter connected to the balance and AC power unless the
balance is not to be used for a long period of time.

4-1 Smart Range Function
The GX-8202MD, GF-8202MD, GX-32001MD and GF-32001MD are equipped with two ranges of
"precision range" of a higher resolution and "standard range" of normal resolution.
The range is switched automatically depending on the value displayed.
Placing a heavy container on the weighing pan and pressing the RE-ZERO key allows the
balance to weigh in the pr ecision range. (Smart range fu nc t i on)
The range can be fixed to the standard range, by pressing the SAMPLE key.
Note
Once the range is switched to the standard range, it will not switch to the precision range
automatically even when the displayed value becomes within the precision range value. Press
the RE-ZERO or SAMPLE key to use the precision range again.
Example
GX-32001MD and GF-32001MD, precision range = 6.2 kg x 0.1g,
standard range = 32.2 kg x 1 g.
Step 1 Press the RE-ZERO key.
The balance will start weighing, using the
precision range.
Step 2 Place a container on the weighin g pan.
When the weighing value exceeds the
precision range, the range will be
switched to the standard range.
Step 3 Press the RE-ZERO key.
The balance will be switched to the precision
range.
Step 4 Place a sample on the pan.
When the weighing value is within the
precision range, the balance will perform a
weighing using the precision rang e.

This is the mode to determine the number of objects in a sample based on the standard sample unit
mass. Unit mass means the mass of one sample. The smaller the variables in each sa mp le un it ma ss
is, the more accurate the counting will be. This series balance is equipped with the Automatic
Counting Accuracy Improv em ent ( ACAI) function to improve t he counting accuracy.
Note
* For counting, use samples that have a unit mass at least ten times greater than that of the
minimum display in grams.
* If the sample unit m ass variable is too large, it may cause a counting error.
* To improve the counting performance, use the ACAI function frequently or divide the samples
into several groups an d count each group.

Note
* If the balance judges that the mass of the samples is too light to
acquire accurate weighing, it displays an error requiring the addition
of more samples to the specified number and press the PRINT..
key. When the unit mass is stored correctly, the balance proceeds to

Danger：Sensor may be damaged
The GX-M / GF-M series has a function to detect impact to the mass sensor section and to display
the impact level.
By lowering the impact level at the time of loading, it is possible not only to alleviate variation in the
weighing value but also to r educ e t he r isk of failure of the mass sen sor section.
Especially when incorporating the balance in a production line, etc. and weighing by means such as
an automated system, impact to the sensor may be applied greater than expected.
When designing automatic systems and the like, it is recommended that you minimize the impact
level as much as possible while checking the shock indicat or.
Impact level display is from level 0 to level 4, 5level.
