3-2 During Use
The FX-
i
WP series balance has a casing with high sealing
performance due to its dust-tight and waterproof design.
Therefore, a very subtle change in the atmospheric
pressure in the installation site, for example, generated by
opening or closing the door, affects the weighing and may
yield an unstable weight value. Wait for the atmospheric
pressure to stabilize before weighing.
If the residue of a powdery or liquid material is left on the
waterproof diaphragm or the pan boss, it may cause
weighing errors. Clean them before weighing.
If the waterproof diaphragm is deformed due to
overloading, it may cause weighing errors. Remove the
load and wait for the waterproof diaphragm to restore to
the original shape before continuing with weighing.
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.
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.
