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.
Cancel the temperature difference between a 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 a 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 cancel
possible errors.
Take into consideration the affect of air buoyancy on a
sample when more accuracy is required.
Keep the balance interior free of dust and foreign
materials.
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.
Do not allow the balance to be immersed in water. Even though the balance complies with
IP65 (Dust-tight and Protected Against Water Jets), the balance will not withstand being
completely immersed in water.
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 (refer to “3-5 Display Symbols and Key Operation”). 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.
