Assemble the pan support, weighing pan and breeze break, on the balance as shown in the
illustration on page 4.
FX-1200i /2000i /3000i
Assemble the pan support and weighing pan on the balance as shown in the illustration on page 4.
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
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.
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.
The breeze break (FX-120i /200i /300i only) 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 “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.
3-5 Display Symbols and Key Operation

5. WEIGHING
5-1 Basic Operation (Gram Mode)
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,
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 FX-i 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 pcs (counting mode).
1
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.
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 balance or samples on the pan until the processing indicator turns off.
10 Counting accuracy is improved when the processing indicator turns off.
Each time the above operation is performed, a more accurate unit mass will be obtained.
There is no definite upper limit of ACAI range for the number of samples exceeding 100. Try
to add the same number of samples as displayed.
11
Remove all the samples used in ACAI and proceed with the counting operation using the
improved unit mass.
5-3 Percent Mode (%)
This is the mode to display the weight value in percentage compared to a 100% reference mass and
is used for target weighing or checking the sample variable.
Selecting the percent mode
1 Press the MODE key to select % (percent mode).
Storing the 100% reference mass
2 Press the SAMPLE key to enter the 100% reference
mass storing mode.
Even in the storing mode, pressing the MODE key will
switch to the next mode.
3 Place a container on the weighing pan, if necessary.
Press the RE-ZERO key to cancel the weight (tare). The
balance displays 100 0 % .
4 Place the sample to be set as the 100% reference mass
on the pan or in the container.
5 Press the PRINT key to store the reference mass. The
balance displays 100.00 % . (The decimal point position
depends on the reference value. The reference mass
stored, even if the AC adapter is removed, is maintained
in non-volatile memory.)
Note
If the balance judges that the mass of the sample is too
light to be used as a reference, it displays lo . Do not use
the sample.
6 Remove the sample.
Reading the percentage
7 Place a sample to be compared to the reference mass on
the pan. The displayed percentage is based on the 100%
reference mass.
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.
5-4 Statistical Calculation Mode
The statistical calculation mode statistically calculates the weight data, and displays or outputs the
results. To use the statistical calculation mode, set the "Application function (apf)" parameter of
“Application (ap fnc)” in the function table to “2”, as described below.
Statistical items available are number of data, sum, maximum, minimum, range
(maximum-minimum), average, standard deviation and coefficient of variation. What statistical items
to output can be selected from the three modes in the function table.
The wrong data input can be canceled by the key operation, if immediately after the input.
Turning the balance off will delete the statistical data.

7. CALIBRATION
7-1 Calibration Mode
The FX-i series balance has the following two modes.
Calibration using an external weight
Calibration test using an external weight (Calibration test does not perform calibration.)
Terms
The following terms are defined as follows:
External weight
= A weight that you have. Referred to as a calibration weight when used for
calibration.
Calibration weight = A weight used for calibration
Target weight
= An external weight used for calibration test
Caution
Calibration adjusts the balance for accurate weighing.
Besides periodic calibration and before each use, perform calibration when:
• The balance is installed for the first time.
• The balance has been moved.
• The ambient environment has changed.
Do not allow vibration or drafts to affect the balance during calibration.
To output the data for GLP using the RS-232C serial interface, set “GLP output ( info )” of
“Data output ( dout )”. For details, refer to “9. FUNCTION TABLE”.
Calibration test is available only when “GLP output ( info )” of “Data output ( dout )” is set to “1” or “2”.

5t-b 0
This parameter is for sensitive response of the stabilization indicator. Used
for exact weighing.
5t-b 2
This parameter ignores slight fluctuation of a weight value. Used to prevent
a weight value from drifting due to vibration or drafts.
Note
With “Hold function (Hold)” set to “ON (1)”, this item is used to set the
stabilization range.
Hold function ( Hold ) (Animal weighing mode)
This function is used to weigh a moving object such as an animal.
When the weight data is over the weighing range from zero and the display fluctuation is within the
stabilization range for a fixed period of averaging time, the processing indicator illuminates and the
balance displays the average weight of the animal. When the animal is removed from the weighing
pan, the display returns to zero automatically.
This function is available only when the hold function parameter is set to “1” (the animal mode
indicator ANIMAL illuminates) and any weighing unit other than the counting mode is selected.
The stabilization range and averaging time are set in “Condition (Cond)” and “Stability band width (5t-b)”.

14-3 Using Windows Communication Tools (WinCT)
When Windows is used as an operating system in a personal computer, the WinCT software, that
is downloaded from the A&D website, can be used to transmit the weight data to the personal
computer.
The WinCT has two communication methods: “RsCom” and “RsKey”.
RsCom
Can transmit commands to control the balance.
Can make bi-directional communication between the balance and a personal computer using
the RS-232C serial interface.
Can display or store the data using a text file format. Can also print the data using a printer
connected to the personal computer.
When several ports of a personal computer have balances connected, can communicate with
each balance simultaneously.
Can share a personal computer with other application software.
RsKey
Can transmit the weight data output from the balance directly to other application software
such as Microsoft Excel.
Can be used with most application software.
Using the WinCT software, the balance can do the following:
1 Analyzing the weight data and the statistics with “RsKey”
The weight data can be input directly into an Excel worksheet. Then, Excel can analyze the
data to obtain sum, average, standard deviation, maximum and minimum value, and display
them in a graph.
2 Controlling the balance using commands from a personal computer
By using “RsCom”, the personal computer sends commands such as “re-zero” or “send weight
data” to the balance and controls the balance.
3 Printing the balance GLP report using your printer
The balance GLP report can be printed using a printer connected to the personal computer.
4 Receiving weight data at a certain interval
The weight data can be received at a certain interval and data characteristic with elapsed time
can be obtained.
5 Using a personal computer as an external indicator
With the “RsKey” test mode function, a personal computer can be used as an external weight
indicator for the balance. (To do this, set the balance data output mode to stream mode.)
15. COMMANDS
15-1 Command List

15-2 Acknowledge Code and Error Codes
When the “AK, Error code (erCd)” parameter of “Serial interface ( 5if )” is set to “1”, the balance
outputs <AK> code or an error code for each command as follows:
<AK> (06h) Acknowledge in ASCII code.
When the balance receives a command to request data and can not process it, the balance
transmits an error code (EC, Exx).
When the balance receives a command to request data and can process it, the balance
outputs the data.
When the balance receives a command to control the balance and can not process it, the
balance transmits an error code (EC, Exx).
When the balance receives a command to control the balance and can process it, the balance
transmits the acknowledge code.
Among commands to control the balance, the following transmit the acknowledge code both
when the balance receives the command and when the balance has accomplished the
command. If the command can not be processed properly, the balance transmits an error code
(EC, Exx). This error can be released using the CAL command.
CAL command (Calibration command)
ON command (Display ON command)
P command (Display ON/OFF command)
R command (RE-ZERO command)
R command example
T command example
PT command example
When a communication error has occurred due to external noise, or a parity error has
occurred due to transmission error, the balance transmits an error code. In this case, send the
command again.
15-3 Settings Related to RS-232C
Concerning the RS-232C, the balance has two functions: “Data output ( dout )” and “Serial interface
( 5if )”. Set each function as necessary.
16. MAINTENANCE
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.
Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or
repair.
Use the original packing material for transportation.
17. TROUBLESHOOTING
17-1 Checking the Balance Performance and Environment

21. TERMS/INDEX
Terms
Stable value
The weight data when the stabilization indicator appears.
Environment
Ambient conditions such as vibration, drafts, temperature, static electricity and
magnetic fields which affect the weighing operation.
Calibration
Adjustment of the balance so that it can weigh accurately.
Output
To output the weight data using the RS-232C serial interface.
Zero point
A weighing reference point or the zero display. Usually refers to the value
displayed when nothing is on the weighing pan.
Digit
Unit of digital resolution. Used for the balance, a unit of minimum weighing value.
Tare
To cancel the weight of a container which is not included in the weight data.
Mode
Balance operational function.
Re-zero
To set the display to zero.
GLP
Good Laboratory Practice.
Repeatability
Variation in measured values obtained when the same weight is placed and
removed repetitively. Usually expressed as a standard deviation.
e.g. Standard deviation=1 digit: This means that measured values fall within ±1
digit in the frequency of about 68%.
Stabilization time Time required after a sample being placed, until the stabilization indicator
illuminates and the weight data is displayed.
Sensitivity drift
An affect that a change in temperature causes to the weight data. Expressed as
temperature coefficient.
e.g. Temperature coefficient = 2 ppm/°C : If a load is 300 g and the temperature
changes by 10°C, the value displayed changes by the following value.
0.0002%/°C x 10°C x 300 g = 6 mg
