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 byturning the leveling feet so thatthe bubble in the bubble spirit level is inside
the red circle.
Make sure that the bubble is in the center of the red circle.
Ensure a stable power source when using the AC adapter.
Plug in theAC adapter and warm up the balance for at least one hour.
Calibrate the balance before use or after having moved it to another location.

11
With the FZ-iWP/ FX- iWP series
The meaning of IP-65 is "No ingress of dust. Projected against water jets".
If a powerful water jet is used or the balance is immersed in water, it may cause a
damage that is due to ingress of water.
Confirm that "the plug is inserted firmly into the jack" and "the terminal is covered using
the waterproof cover or the waterproof RS-232C cable (AX-KO2737-500)", when using
the balance.
If the terminal cover for the RS-232C is removed from the balance or the waterproof
RS-232C cable (AX-KO2737-500) is not used for the balance, the balance is prevented
from having the dustproof and waterproof performance.
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 optionalAD-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.
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.

12
With all models of FZ-i/FZ-iWP/FZ-GD series and the 120/200/300 of the FX-i/FX-i WP/FX-GD
series (including 500 for the FX-i series), a breeze break is provided as a standard accessory.
Since an anti-static treatment has been applied to the breeze break components, there are
cases where they may be charged with static electricity for a while after they are unpacked or
when the humidity is low. If the weight value is unstable even when there are no drafts in the
measurement environment or repeatability cannot be obtained properly, try removing the
breeze break from the balance. Or wipe the clear plates using a cloth dampened with water to
resolve the problem by discharging them. As another approach, using the optional AD-1683 DC
static eliminator or applying an anti-static spray is also effective.
With the FX-iWP/ FZ-iWP series
The balance has a highly airtight case due to it having dustproof and waterproof performance.
Therefore, there are cases when the values displayed with the balance become unstable due to
minute indoor pressure fluctuations such as when opening or closing the room door. Try
measuring after stabilizing the pressure fluctuations.
If water droplets or powder remain on the diagram for achieving waterproof performance or on
the pan support boss, there may be cases where proper performance cannot be obtained from
the balance. Use the balance after cleaning those.
If the diagram for achieving the waterproof performance is deformed for reasons such as
excessive load being applied, there may be cases where the values displayed on the balance is
unstable until the deformation is fixed.
3.3. After Use
Do not apply excessive shock to the balance or allow it to be dropped.
Do not disassemble the balance.
Do not use organic solvents or chemically treated cloth to clean the balance. When cleaning
other than the breeze break, wipe using a lint free soft cloth dampened with water and a mild
detergent.
An anti-static treatment has been applied to the breeze break components. Wipe them with dry
and a lint free soft cloth. Wiping them using a cloth dampened with water or a mild detergent
repeatedly or washing them using water may cause the anti-static treatment performance to
decrease.
When cleaning the weighing pan, handle it carefully so that your fingers are not injured by the
edges.
3.4. Power Supply
When theAC 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.

With the zero point setting, tare and weighing range
About the operation at when power is turned on
The balance will determine the reference zero point when the ON:OFF key is pressed to enter the
weighing mode.
Depending on the load condition at that time, it will automatically judge whether to perform zero or tare
operation. The condition for determining which is used is "power on zero range", and when power on
zero range is exceeded, the tare subtraction operation is performed.
About re-zero operation
By pressing the RE-ZERO key, the display can be changed to zero.
Re-zero with the RE-ZERO key will automatically determine whether zero or tare operation is
performed.
The condition for determining which is used is "zero range",and when zero range is exceeded, the tare
subtraction operation is performed.
About measurement range
For the balance, the range that can be weighed is determined by model.
The total amount (net amount + tare quantity) up to the maximum display of each model is displayed,
and when the maximum display is exceeded, E is displayed to indicate that the weighing range is
exceeded.
When in excess in negative, -E is displayed.

6.4. Counting Mode (PCS)
This is the mode to determine the number of objects in a sample based on the standard sample unit
mass. The unit mass means the mass of one piece of the sample. The smaller the variables in each
sample unit mass are, the more accurate the counting will be. The balance is equipped with the
Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Notes
For counting, use samples with a unit mass of at least ten or more times the minimum
weighing value of the balance,.
If the sample unit mass variable is too large, it may cause a counting error.
To improve the counting performance, use the ACAI function frequently or divide the samples
into several groups and count each group.
Selecting the counting mode
1 Press the MODE key to select 1pcs (counting mode).
Storing a sample unit mass
2 Press the SAMPLE key to enter the sample unit mass
storing mode.
Even in the storing mode, pressing the MODE key will
switch to the next mode.
3 To select the number of samples, press the SAMPLE key
several times. It may be set to 5, 10, 25, 50 or 100.
Note
A greater number of samples will yield more accurate
counting result.
4 Place a container on the weighing pan, if necessary.Press
the RE-ZERO key to cancel the weight (tare). The number
specified in step 3 appears.
e.g.: 25 0 is displayed if 25 is selected in step 3.
5 Place the number of samples specified on the pan. In this
example, 25 pieces.
6 Wait for the stabilization indicator to turn on. Press the
PRINT key to calculate and store the unit mass. The
balance displays 25 pcs (counting mode) and is set to
count samples with this unit mass.
To improve the accuracy of the unit mass, go to step 8.
