2-2 Installing the Balance
Install the balance as follows:
1. Place the balance on a solid weighing table. Refer to “3. PRECAUTIONS” for installing the balance.
2. In case of FZ-iWP series and FX-120iWP / FX-200iWP / FX-300iWP
Assemble the pan support, weighing pan and breeze break, on the balance as shown in the
illustration on page 7.
In case of FX-1200iWP / FX-2000iWP / FX-3000iWP
Assemble the pan support and weighing pan on the balance as shown in the illustration on page 7.
3. Adjust the leveling feet to level the balance. Confirm it using the bubble spirit level.
4. Confirm that the AC adapter type is correct for the local voltage and power receptacle type.
5. Connect the AC adapter to the balance. Warm up the balance for at least 30 minutes with nothing
on the weighing pan.
Note
The AC adapter plug is protected against dust and may be difficult to insert. When inserting the
plug, turn the plug while pushing on it.

3. PRECAUTIONS
To get the optimum performance from the balance and acquire accurate weight data, note the following:
3-1 Before Use
The meaning of IP65 is "No ingress of dust. Projected against water jets".
If a powerful water jet is used or the balance is immersed in water, the
ingress of water may cause damage to the balance.
Confirm that "the plug is inserted firmly into the AC adapter jack" and "the
RS-232C interface connector is covered using the terminal cover or the
waterproof RS-232C cable (AX-KO2737-500) is connected", when using
as a dust and waterproof balance.
When the balance is used without the terminal cover on the RS-232C
interface connector or a standard RS-232C cable is used, the balance
does not comply with IP65.
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
The FZ-iWP series and the FX-iWP 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.
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.

11
Prevent foreign materials, such as powder, liquid and metal, from invading the area around the
weighing pan.
The breeze break (FZ-iWP series and FX-120iWP / FX-200iWP / FX-300iWP ) 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
Do not allow the balance to be immersed in water. Even though the balance complies with IP code,
the balance will not withstand being completely immersed in water.
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.
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 “3-5 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.

1 Place a container on the weighing pan, if necessary.
Press the RE-ZERO key to cancel the weight (tare).
The balance displays 0.00 g. (The decimal point position
depends on the balance model.)
2 Place a sample on the pan or in the container.
3 Wait for the stabilization indicator to be displayed. Read the value.
While the stabilization indicator is on, pressing the PRINT key
will output the weight value, using the RS-232C serial interface.
Note
Peripheral equipment, that is sold separately , such as a
printer or a personal computer is required.
4 Remove the sample and container from the pan.
Notes
To use other units, press the MODE key and select an appropriate unit.
Press the SAMPLE key to turn on or off the minimum weighing value.
When the ON:OFF key is pressed with a container placed
on the weighing pan, the balance displays 0.00 g and
weighing is started,

17
5-2 Counting Mode (PCS)
This is the mode to determine the number of objects in a sample based on the standard sample unit mass.
Unit mass means the mass of one sample. The smaller the variables in each sample unit mass are, the
more accurate the counting will be. The FZ-iWP series and the FX-iWP series balance is equipped with
the Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Note
If the sample unit mass variable is too large, it may cause a counting error.
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 come 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. (The sample unit mass
stored, even if the AC adapter is removed, is maintained in
non-volatile memory.)
To improve the accuracy of the unit mass, proceed to step 8.
Notes
If the balance judges that the mass of the samples is too
light and is not adequate to be used as the unit mass, it
displays lo . In that case, store the mass by some
quantity. For example, when the model with the minimum
weighing value of 0.01 g is used and 10 pieces of samples
weigh 0.05 g. Store 100 pieces of samples as 10 and multiply
the weighing result by 10.

18
If the balance judges that the mass of the samples is too light
to aquire accurate weighing, it displays an error requiring the
addition of more samples to the specified number. In the
example above, 150-
PCS appears, requiring 25 more samples.
Add 25 samples and press the PRINT key. When the unit
mass is stored correctly, the balance proceeds to the counting
mode.
Counting operation
7 Place the samples to be counted on the pan.
While the stabilization indicator is on, pressing the PRINT key
will output the weight value, using the RS-232C serial interface.
Note
Peripheral equipment, that is sold separately , such as a
printer or a personal computer is required.
Counting mode using the ACAI function
The ACAI is a function that improves the accuracy of the unit
mass automatically by increasing the number of samples and
averaging the unit mass variable to minimize the weighing error,
as the counting process proceeds.
8 If a few more samples are added, the processing indicator turns on. To prevent an error, add three or
more. The processing indicator does not turn on if overloaded. Try to add the same number of
samples as displayed.
9 The balance re-calculates the unit mass while the processing indicator is blinking. Do not touch the
