Introduction
Thank you for purchasing a Shimadzu TW/TX/TXB series
electronic balance.
The TW/TX/TXB series models are high performance electronic
balances that we condently recommend based on over 80 years of
precision balance manufacture. While these models are of course
capable of fast and accurate weighing, the TW/TX models all
use the Unibloc cells that Shimadzu started using for electronic
balances in 1989, and the TXB models use our unique, newly
developed and robust load cells, improving the reliability of the
balances still further.
The new TW/TX/TXB series balances also feature operation keys
for four directions, improving operating convenience and making
the balances easier to use.
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 TW/TX/TXB 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 classied and
indicated as shown below.
!

eld
Instru ction s
Instru ction s
Install the balance on a
strong and stable at table
or oor.
Placing the balance in an unst able site
could lead to injury or t rouble with
the bala nce.
When selecting the installation site,
take into account the combined
weight of the balance and the item to
be weighed.
After a power outage, turn
the power back ON.
When a power outage occurs, the
power is shut off automat ically.
Therefore, begin operation from
"Turning the Power ON" (^ page
31) again.
Instru ction s
Instru ction s
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 pan and pan
suppor ter. Grasp it rmly with bot h hands to car ry it.
If the balance has to be stored for a long t ime, store it in
the packaging box in which it was delivered.
Use the correct weighing units.
Using incorrect weighing un its can lead to accidents as
a result of weighing errors.
Check that the weighing u nits are cor rect before
star ting weighing.

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
simplied 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.
12
Action for Environment (WEEE)
To all user of Shimadzu equipment in the European Union:
Equipment marked with this symbol indicates that it was sold on or after 13th August 2005,
which means it should not be disposed of with general household waste. Note that our equipment
is for industrial/professional use only.
Contact Shimadzu service representative when the equipment has reached the
end of its life. They will advise you regarding the equipment take-back.
With your co-operation we are aiming to reduce contamination

Installation
Choosing the Installation Site
The measuring performance of the balance is greatly inuenced by the environment where it is
installed.
Observe the following points to ensure safe and accurate weighing.
! Caution
Do not use the balance anywhere
exposed to explosive, combustible
Prohibi tions
or corrosive gases.
This could cause re or t rouble.
Instru ction s
Prohibi tions
Use the correct power supply and voltage with the balance.
Using an incorrect power supply or voltage with the balance will lead to re or trouble
with the balance.
Note also that if the power supply or voltage is u nstable or if the power supply capacit y
is insufcient, it will not be possible to obtain sat isfactory perfor mance from the
balance.
Precautions on Use
Avoid locations where the balance will be exposed to any of the
following.
Air ow from an ai r conditioner,

Adjusting the Level of the Balance
The level of this balance is maintained by three-point suppor t involving a single xed foot at
center rear on the underside of the main body and two level screws on left and right at the f ront
of the underside of the main body.
The large pan model also has level screws on left and right at the back, but they are used in an
auxiliary role to prevent the balance from tilting when a heavy sample is placed on the pan.
Operation of the level screws
