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.
The breeze break (GX-200/300/400/600/800/1000 only) and the clear main unit cover are
provided as accessories. The breeze break components may be charged with static electricity
when they are unpacked or when the humidity is low. If the weighing value is unstable or the
balance has a problem with repeatability, remove the breeze break. Or wipe the clear plates
with a moistened cloth, use an accessory DC static eliminator, AD-1683, or apply an anti-static
spray.
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.
Avoid dust and water so that the balance weighs correctly. Protect the internal parts from liquid
spills and excessive dust.
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
