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 ten million counts. Therefore, there are
tendencies to be influenced by temperature change, air pressure change, static electrisity,
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 floor are best, as they are less prone to vibration.
The weighing table should be solid and free from vibration, drafts and as level as possible.
Level the balance by adjusting the leveling feet and confirm it using the bubble spirit level.
If static electricity is a problem at the installation site, use the electrostatic field meter and the
static eliminator.
Ensure a stable power source when using the AC adapter.
Connect the AC adapter and warm up the balance for at least 30 minutes.
Calibrate the balance periodically for accurate weighing.
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 (GX-07K)", when using the balance.
Use the waterproof option cable GX-07K, when the RS-232C interface is used with IP-65.
AX-KO1710-200, a standard 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.
8
3-2. During Use
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 using an optinal static
eliminator, AD-1683.
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 from the
influence of the magnet.
Eliminate any temperature difference between the sample and the
environment. When a sample is warmer (cooler) than the ambient
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 press the keys.
Use your finger only.
Press the RE-ZERO key before each weighing to prevent
possible errors.
Calibrate the balance periodically so as to eliminate possible errors.
Take into consideration the affect of air buoyancy on a sample
when more accuracy is required.
It is possible to check the reference card for principle operation.
Prevent foreign matter, such as powder, liquid and metal, from invading the area around
the weighing pan.
Use the "breeze break" for a precision weighing.
3-3. After Use
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.
9
Do not allow the balance to be immersed in water. Even though the balance complies 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 balance. Clean
by splashing with water.
Use the waterproof option RS-232C cable GX-07K, when RS-232C interface is used with
IP-65. AX-KO1710-200, a standard RS-232C cable, is not waterproof or dustproof.
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.
