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 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 caused by the evaporation of moisture
from the sample or the absorption of moisture by the sample.
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 eliminate 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.
Keep the balance interior free of dust and foreign materials.
The breeze break (The FZ-

(only)) is provided as a
standard accessory. An anti-static treatment has been applied to the breeze break components,
but they may be charged with static electricity when they are unpacked or when the humidity is
low. If the weight value is unstable even when there are no drafts or the balance has a problem
with repeatability, remove the breeze break. Or wipe the clear plates with a moistened cloth, use
the optional AD-1683 DC static eliminator 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.
The edge of the weighing pan is sharp. Use much care when cleaning the pan.
Avoid dust and water so that the balance weighs correctly. Protect the internal parts from liquid
spills and excessive dust.
3-4 Power Supply
When the AC adapter is connected, the balance is in the standby mode if the standby
indicator is on (refer to “4. DISPLAY SYMBOLS AND KEY OPERATION”). This is a normal
state and does not harm the balance. For accurate weighing, warm up the balance for at least
30 minutes before use.
