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.
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. 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 (The FZ-CT / FX-CT series) 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.
