10
3. PRECAUTIONS
To get the optimum performance from the balance and acquire accurate weight data, note the
following:
3-1 Before Use
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 which
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.
Ensure a stable power source when using the AC
adapter.
Plug in the AC adapter and warm up the balance for at
least 30 minutes.
Calibrate the balance before use or after having
moved it to another location.
Caution
Do not install the balance where flammable or corrosive gas is present.
3-2 During Use
Discharge static electricity from the material to be
weighed (hereinafter referred to as the sample). When
a sample could have a static charge, the weight data is
influenced. Ground the balance and try the following:
Eliminate static electricity using the optional
AD-1683 DC static eliminator.
Try to keep the ambient humidity above 45%RH.
Use a metal shield case for a charged sample.
Wipe charged plastic samples with a moistened
cloth.
11
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.
For balances with a minimum weighing value of 0.001g or less, use a pair of long tweezers to
place a sample on the pan to avoid placing a hand inside the breeze break.
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 (FZ-GD series (all models) and FZ-300CT/600CT and
FX-300CT/600CT/120GD/200GD/300GD) is provided as an 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.

8. FUNCTION SWITCH AND INITIALIZATION
8-1 Permit or Inhibit
The balance stores parameters that must not be changed unintentionally. There are two switches for
the purpose of protecting these parameters. Each switch can select either “permit” or “inhibit”. The
“inhibit” protects parameters against unintentional operations.
