Introduction
Thank you for purchasing a Shimadzu ATX/ATY series electronic
balance.
The ATX/ATY series models are high performance electronic
balances that we condently recommend based on over 90 years of
precision balance manufacture. While these models are of course
capable of fast and accurate weighing, the models all use the
Unibloc cells that Shimadzu started using for electronic balances
in 1989, improv the reliability of the balances still further.
These balances also feature a variety of other functions that
make it more convenient for customers to use them for their
own applications, including the WindowsDirect communication
function, which enables measuring results to be transferred to a
PC without installing any software.
To ensure that you can make full use of the performance and
functions of your ATX/ATY series balance, read this instruction
manual carefully and use the balance correctly in accordance with
the directions in the manual. When you have nished reading the
manual, keep it in a safe place together with the balance so that
you can refer to it at any time.
For information on the following points, please contact your
Shimadzu Balance representative.

Safety Precautions To be strictly observed
To ensure that you use the balance safely and correctly, read the following precautions carefully and observe
them.
The levels of danger and damage that will arise if the balance is used incorrectly are classied and
indicated as shown below.
! CAUTION
Indicates a potentially hazardous situation which, if not avoided, may result in minor to
moderate injury or equipment damage.
Precautions are classied and explained by using one of the symbols below, depending on the nature
of the precaution.
Instructions
Indicates an action that must be
performed.
Prohibitions
Indicates an action that must
NOT be performed
! CAUTION
Prohibitions
Do not use the balance
outdoors or anywhere where
it will be exposed to water.
You could sustain an electric shock or
the product could operate abnormally.
Prohibitions
Never disassemble, modify or attempt to
repair this product or any accessory.
You could sustain an electric shock or the product could
operate abnormally.
If you believe that the balance has failed, contact your
Shimadzu representative.
Instructions
Use the balance with the correct power
supply and voltage.
Use the balance with the attached AC
adapter.
Using the balance with an incorrect power supply or
voltage will lead to re or trouble with the balance.
Note also that if the power supply or voltage is unstable
or if the power supply capacity is insufcient, it will not
be possible to obtain satisfactory performance from the
balance.
Prohibitions
Do not connect anything other than
peripheral devices specied by Shimadzu
to the balance’s connector.
If you do, the balance may stop working normally.
In order to avoid trouble, always connect peripheral
devices in accordance with the directions in this manual.
Instructions
If you detect anything
abnormal (e.g. a burning
smell) disconnect the AC
adapter immediately.
Continuing to use the balance with
an abnormality could lead to re or
an electric shock.
Prohibitions
Do not use the balance
anywhere exposed to
explosive, combustible or
corrosive gases.
This could cause re or trouble.

9
Precautions on Use
Prohibitions
Avoid locations where the balance
will be exposed to any of the
following.
You may not be able to obtain correct weight
readings.
Air ow from an air conditioner, ventilator,
door or window
Extreme temperature changes
Vibration
Direct sunlight
Dust, ne particles, electromagnetic waves
or a magnetic eld
•
•
•
•
•
Instructions
Treat the balance with care and respect.
The balance is a precision instrument. Subjecting it to
impacts could cause it to fail.
When moving the balance, remove xing of the glass
door, pan, pan supporter and pan rings. Grasp it rmly
with both hands to carry it.
If the balance has to be stored for a long time, store it in
the packaging box in which it was delivered.
Instructions
Install the balance on a
strong and stable at table
or oor in the room.
Placing the balance in an unstable site
could lead to injury or trouble with
the balance.
When selecting the installation site,
take into account the combined
weight of the balance and the item to
be weighed.
Instructions
Use the correct weighing units.
Using incorrect weighing units can lead to accidents as
a result of weighing errors.
Check that the weighing units are correct before
starting weighing.
Instructions
After a power outage, turn
the power back ON.
When a power outage occurs, the
power is shut off automatically.
Therefore, begin operation from
"Turning the Power ON" (^page
29) again.

Shimadzu Balances and 21 CFR Part 11
21 CFR Part 11
21 CFR Part 11, Electronic Records, Electronic Signatures, Final
Rule (often referred to as Part 11) is the United States Food and Drug
Administration (FDA) regulation affecting computer resources and
electronic records that are used for any document that is required to be
kept and maintained by FDA regulations.
Requirements concerning computer resources security are key
elements in Part 11.
The controls implemented as a result of security related requirements
are intended to result in trusted records.
Shimadzu CLASS-Balance Agent
Shimadzu provides a means for compliance with 21 CFR Part 11 with
Shimadzu CLASS-Balance Agent software, part of a comprehensive
laboratory data management system, Shimadzu CLASS Agent.
Ask your Shimadzu representative about it.
Shimadzu WindowsDirect
When Shimadzu balances are integrated with laboratory software by
means of our WindowsDirect function, no communication software is
required or used.
The Shimadzu balance functions as a primary device in the system,
just as a keyboard, mouse or other data entry hardware does.
For this reason, system validation and compliance may be greatly
simplied with the use of Shimadzu balances.
Two-way Communication
Shimadzu balances have always been computer friendly and they can
be set up for bi-directional communication as part of a fully automated
production system or LIMS.
This manual includes the command codes and information needed by
programmers to integrate Shimadzu balances with their software.

11
