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

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.

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.

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
The balance is a precision instrument. When the operating environment or the operating method is
inadequate, correct weighing can not be performed. Place a sample on the pan and remove it, and
repeat this several times. If the balance seems to have a problem with repeatability or to perform
improperly, check as described below. If improper performance persists after checking, contact the
local A&D dealer for repair.
Checking that the balance performs properly
Check the balance repeatability using an external weight. Be sure to place the weight in the
center of the weighing pan.
Check the balance repeatability, linearity and calibrated value using external weights with a
known value.
