 1. Introduction

1. Introduction
Shimadzu UW/UX series of toploading balances are a product of our 80 year history of developing and
manufacturing weighing instruments.

For Basic Operation

Shimadzu UW/UX series of toploading balances utilize the patented Shimadzu UniBloc sensor, intro-
duced in 1989, to achieve high performance, fast response, and durability. Available features include
multiple units of measure, piece counting, checkweighing functions, auto print, and GLP/GMP/ISO out-
put including date and time data from a built-in clock.
The new series also features Shimadzu’s WindowsDirect communication, requiring no software instal-
lation to quickly integrate balances with lab or business software. This function eliminates data input
errors and offers extensive flexibility for application development without compromising compliance or
data security.
The UW series balance incorporates a motor-driven built-in calibration weight that can automatically
calibrate sensitivity without the use of external weights.

Read this manual carefully before using this instrument and keep it with the balance for future refer-
ence.

This manual refers to the different types of UW and UX series (UW/UX series) balances as follows:
H type: UW/UX H
S type: UW/UX S
Where: represents the figure indicating the capacity, H indicates high resolution and
S indicates standard resolution.
Suffix “V” is added for models with EC Type Approval.
The type of balance is classified as “large pan” or “small pan” depending on the capacity. The small
pan models with minimum display of 0.001g come with a standard windbreak. Accordingly, the models
are classified into the following three groups in “4. Installation”.
a. Large pan models: Capacity 2200g or higher
b. Small pan models: Capacity 820g or lower (minimum display 0.01g)
c. Small pan models: Capacity 1020g or lower (minimum display 0.001g, windbreak standard)

4.5 Span Calibration

Note
Using a verified balance as a legal measuring instrument in using region:

For Basic Operation

Span calibration must be performed once the balance is installed and
before using the balance as a legal measuring instrument in using region.
Span calibration must be performed with the internal calibration weight to
maintain the verification valid. The balance must be connected to power
and warmed up for at least 2 hours prior to span calibration and use as a
legal measuring instrument.

It is necessary to calibrate the balance after it is moved.

Verify that the balance is stable before performing the span calibration. To achieve a very stable state,
ensure that the balance has been turned on with the gram-display for at least one hour, that the tem-
perature is constant, that there are no breezes or vibrations and that the balance is in an area isolated
from the normal traffic flow.

 6. WindowsDirect Function

6. WindowsDirect Function
6.1 Introduction: Experience it!
The UW/UX series balance can transfer data directly to a computer running MS-Excel, mass input win-
dow of analytical instrument software or other applications on Windows®* OS, as if the displayed value
were typed from the keyboard to the cursor position. This function is called WindowsDirect. As this func-
tion directly accesses the Windows® OS, communication software-installation troubles are eliminated.
A cable and a few simple settings are all that is needed to enable data transmission from the balance.
For bi-directional communication between the balance and the computer, software is required. Win-
dowsDirect does not send commands from the computer.
• Only numerical values can be transferred through WindowsDirect.

6.2 Set Up WindowsDirect

Simple settings are made for the balance and the computer. Connection is by RS-232C cable (15.2.1)
specified by Shimadzu.
If bi-directional communication software is used: WindowsDirect function should be turned off. Set up the opti-
mal communication parameters for the software according to “15.3 Communication setting”.

6.2.1 Setting Up the Balance

1 Press the [MENU] key twice from the gram-dis-
play. “Setwin” appears.

2 Press the [O/T] key. Verify the stability mark is

illuminated with “Setwin” display. All the communi-
cation settings for WindowsDirect have been made.

3 Go to “STAND-BY” by pressing the [POWER]

key several times and unplug the AC adapter
from the balance. Unpluging the balance once is
necessary after the above setting.

Notes
• Individual communication parameters can be changed at any time using the communications set-
tings menu. If WindowsDirect communication settings have been previously made, the → (stability
mark) may appear with the “SEtwin” display even after communication settings are changed and
become invalid for WindowsDirect. To restore WindowsDirect optimal settings, first go to the "SEt-
win" display and remove the stability mark by pressing the [O/T] key. This restores the default com-
munication settings. Then, reset “SEtwin” following the procedure described in 6.2.1.
• Refer to 15.3 for details of communication settings.

 6. WindowsDirect Function

6.3 Troubleshooting the WindowsDirect

Communication Function
If the WindowsDirect communication function doesn't run properly, check the following points.
If this doesn't resolve the problem, contact your Shimadzu representative.

Q1 WindowsDirect communication has been set but it is not operating at all.

A1
• Check the type of communications cable used for the connection (Shimadzu authorized part or
another part available on the general market) and the soundness of the connection.
• If a USB serial converter is used, depending on the circumstances at the setup there is a possibility
that it has been automatically set to a COM port number higher than 4, and in this case you should
reassign it to a COM port number that can be used by serial key devices (COM1 to COM4).
• It is possible that the driver used as an accessory with the USB serial converter has not been set up
properly. Try uninstalling the driver and installing it again.
• Some notebook PCs feature a setting for disabling RS-232C ports as a power-saving measure.
Before trying to use the WindowsDirect communication function, make the setting that enables the
use of RS-232C ports.
• Communications with other applications and PCs via a LAN may interfere with the serial key device
settings. Try using WindowsDirect communication without using the LAN.

Q2 The WindowsDirect communication function won't work after I restart the PC.
A2
• Some PCs don't recognize that a serial key device has been set when they start up. For details on
how to deal with this, contact your Shimadzu representative.

Q3 I want to use the WindowsDirect communication function with Windows Vista or

Windows 7.
A3
• Windows Vista doesn't have the serial device setting screen that is required to set the WindowsDi-
rect communication function. For details on the setting, contact your Shimadzu representative.

Q4 Data is input to the PC as garbled characters.

A4
• Either the balance or the PC is not set for the WindowsDirect connection function. Make the settings
again.

28
 6. WindowsDirect Function

Q5 When data is input into Excel, the cursor doesn't move to another cell.
A5
• If a function for conversion to 2-byte characters is available in Windows, turn the setting for this func-
tion off.
• Click the [Edit] tab under [Options] in Excel and check [Move selection after Enter] (if cells move in
response to keyboard input there is no problem).
• Check the input data in another application (e.g. Notepad).

Q6 The operation is sometimes abnormal.

A6
• Depending on the processing capability of the PC, malfunctions may occur if the communications
speed is high. Set 300 bps for the communication speed. Malfunctions may also occur if the interval
for data transmission from the balance is too short. Ensure that one batch of data is displayed on the
screen before the next batch of data is sent. And if there is limited processing capability, don't use
the continuous output function.
• When data is sent from the balance, don't touch the PC's keyboard or mouse.

11.1 Overview
Settings on the balance can be changed to compensate for the installation environment such as the
degree of vibration or air movement or for the purpose of weighing a solid, liquid or powder.

11.2 Stability and Response (Averaging)

It is possible to match the stability of the display and the degree of response with the requirements of
specific applications or the installation environment. One of the five modes can be selected. Note that
adjustments for stability and response conflict with each other, although the UW/UX series is designed
to meet both.

Auto mode: Select menu item 22 .

Read Chapter 7 Before Use of These Pages

The balance automatically performs optimum averaging dynamically while
observing the load data. This is the recommended setting and should be used
unless special circumstances exist.

Pouring mode: Select menu item 23 .

(Filling, dosing) This mode is particularly suitable for dosing or filling purposes.
Note that this mode is very sensitive to wind and vibration.

(Environmental setting in Pouring mode)

Pouring mode allows further adjustments to the surrounding environmental
conditions. Choose the optimal setting for your installation site observing the
response and stability.

Every time the circle in the right part of the [O/T] key is pressed during weigh-
ing in Pouring mode, the environmental setting will be changed and cycles in
the following order. Upon changing the setting, the new setting is briefly dis-
played as shown in “ ”.
normal environment ( “norm E” ) → unstable environment, ( “UnStb E” )
→very stable environment, ( “StAbL E” ) → normal environment, ( “norm E” ).

During use, the current environmental setting of Pouring mode can be con-
firmed by observing the position of the W symbol in the display.

most part of [O/T] key. Press the center or the left part of [O/T] key for tar-
ing or zeroing.

Standard mode: Select menu item 24 .

This mode is suitable for weighing in a normal environment. Averaging is
fixed and does not change dynamically as in the Auto mode.

Anti-vibration mode: Select menu item 25 .

Use this mode when the balance is used in a location where there are large
vibrations and the display fluctuates in the Auto mode.
Response is deteriorated at small mass amount changes.
Read Chapter 7 Before Use of These Pages

Anti-wind mode: Select menu item 26 .

Use this mode when the balance is used in a location where it is exposed to
airflow that causes the display to fluctuate in the Auto mode.
Response deteriorates further than the Anti-vibration mode, but weighing is
comparatively stabilized.

Note
If weighing cannot be performed efficiently even with the Anti-wind mode,
change the installation site of the balance or use the optional windbreak
(large).

11.3 Stability Detection and Settings

Stability detection is an auxiliary function used for the following purposes.
(1) When the weigh is stabilized during measurement, Stability mark is prompted as an auxiliary
indication of measurement stability.
(2) Operations such as data output and auto zeroing of the below listed functions are triggered by
stability detection. Some data output functions operated with communication commands
(15.2.3) are also linked to stability detection.
(Functions that employ stability detection)
Auto Print (See 13.3), Auto Zero (See 13.4), Taring/Printing at Stability (See 13.6), Peak Hold
(See 14.3), Auto-Memory and Zeroing (See 14.5), Animal Weighing (See 14.6), Formulation
Mode (See 14.7).

50
 11. Environment

It is possible to adjust the operation with the following stability detection settings.
(a) Stability Detection Band (11.3.1)
(b) Timing of Stability Mark Illumination and Automatic Output (11.3.2)
It is not usually required to change these settings as they are optimized at default. However, it is
allowed to change according to 11.3.1 and 11.3.2 when: wishing to ease the criteria of stability detec-
tion under very unstable environmental or sample conditions, or wishing to accelerate automatic data
output when using a function that employs stability detection.

Note
Stability mark is an auxiliary device to inform measurement stability. The
displayed value may change while the stability symbol remains illuminated
if the load is changing slowly, or depending on the stability detection set-
tings.

Read Chapter 7 Before Use of These Pages

11.3.1 Stability Detection Band
The default setting is “1 count” and the measurement is regarded to be stable when the display has
remained within one display count for a fixed length of time. If stability detection band is set at
“2 counts”, it will be regarded to be stable when the display has remained within two display counts.
Selecting a larger stability detection band generally eases the criteria and makes stability mark illumi-
nate more readily. However, it will be more likely for the display to further fluctuate after prompt of sta-
bility mark.
Try a larger stability detection band when data outputs triggered by stability detection is slow due to
very unstable environmental and/or sample conditions.

Zero Tracking Function

When the display is zero, tracking functions as “zero tracking” to keep the
zero display as long as possible. “Zero tracking” automatically cancels
small zero drift.
It is recommended to set tracking off when measuring slight mass change
such as in the process of drop addition or liquid evaporation.

Note
Using a verified balance as a legal measuring instrument in using region:
Even when Tracking is ON, the range where it works is restricted to the
vicinity of the zero, and it is subjected to conditions, according to the regu-
lations.

Analog display section

The UW/UX series balance has an analog bar graph located on the left side of the display. This graph
can be conveniently used for checkweighing or cumulative weighing.
The graphic display functions include the two display modes of checkweighing, the target mode, and
full scale mode. Only one of them can be used at a time. Refer to 9.1 for the full scale mode and the no
bar graph display.
Upon selection of either the checkweighing mode or the target mode, the numerical value for threshold
or target is requested. Numeric values are memorized independently for each graphic display mode.
When one of the checkweighing modes is selected, a signal corresponding to HI, GO, or LO in the-
graphic display can be transmitted via the RS-232C/AUX connector.
Target, limit, upper, and lower values are set as numeric values only. Set the correct numerical value
for the unit that will be used for weighing.
• In weighing mode, changing the displayed unit does NOT change the target, limit, upper, or lower
numeric values. For example, when the upper limit has been set at 10g, switching the unit from “g” to
“kg” does not change the limit to 10kg. It will be 0.01kg.
The decimal point is invisible in the value setting display. Determine its position based on the resolution
of the balance. For example, if the balance’s minimum display is 0.01g, 150g must be set by inputting
“15000” in the display.

13.1.3 Target Mode

Read Chapter 7 Before Use of These Pages

This mode is useful for constant amount weighing of liquid or judgment of excess and shortage.
The target value is the numeric value that is the desired amount in the unit that is used for weighing.
The limit value is the numeric amount above or below the target value that is acceptable. The target will
be indicated as the center line in the analog display. The limits will be indicated as triangle marks. A
moving bar represents the current weight on the pan.

13.5 Zero Range

The “Zero Range” value is used in the following functions as a reference for judging whether the sam-
ple is loaded: Auto Print (13.3), Auto Zero(13.4), Peak Hold(14.3), Add-on Mode(14.5), Animal Weigh-
ing Mode(14.6), and Formulation Mode(14.7).
If the display is within the Zero Range, the balance determines that the balance is not loaded. If the
display reaches five times the Zero Range or more, it determines that a sample is loaded. Functions
which involves judgment of whether a sample is loaded or not work in accordance with the Zero Range
setting.

Example: Samples are weighed one after another with UX2200H (minimum display 0.01g) and each
measurement result is automatically output with the Auto Print “on Ld” function (13.3).
Suppose Zero Range is set to 10. As 1 count for UX2200H is 0.01g, Zero Range is 0.10g in
this case. When a sample of 0.50g or more is placed, it is judged to be loaded and the data
will be output. When this sample is removed and the display returns below 0.10g, it is
Read Chapter 7 Before Use of These Pages

judged that the balance is unloaded, then it is ready for the next sample. If it does not return
below 0.10g, the previous sample is not judged to be unloaded. Therefore, even when the
displayed value reaches 0.50g again by next loading, the data will not be automatically output.
Select Zero Range value according to the influences of environment (causing difficulty in
zero-return), the weight of the samples, etc. so that Auto Print functions properly.

Set the “Zero Range” value with menu item 48 using the number of counts displayed in gram-display.
The setting range is 01 to 99 with 10 being the default value. Even when weighing will be done in
another unit, Zero Range setting is made by only gram value.

Notes
• Zero Range value is a common setting for all the Zero Range-linked
functions.
• The application of Zero Range value is different depending on each
function. Refer to the section of each function using Zero Range.
• When a Pretare value is set, the thresholds to determine that there is
“no load” becomes “− Pretare ± Zero Range”.
• When minimum display is changed to 10d (See 9.2), number of counts
used for load/unload judgment is counted based on the 10d minimum
display. Therefore, the Zero Range value optimized for 1d display can
be too large for 10d display. This may cause failure of linked operation,
e.g. automatic output upon loading. Optimize Zero Range value again
when switching minimum display 1d/10d.

Notes
• On the premise of weighing animated objects, the stability detection
band is automatically extended in the Animal Weighing mode. Repro-
ducibility of the measurement data is slightly less than with other modes.
If a larger stability detection band is selected with the menu (See 11.3.1),
stability detection is more readily made and the output of measurement
result usually becomes faster. However, the accuracy may become
poorer. When changing stability detection band, select according to the
specific measurement’s requirements on accuracy, observing the repro-
ducibility on the test run.
• If the balance is slow to automatically return to the zero display, set a
larger Zero Range value.

(1) Basic format

An example of data format of a negative value (-186.65g) with delimiter of C/R is shown.
The data length varies depending on attached information, unit expression and delimiter as
explained in (2).

Read Chapter 7 Before Use of These Pages

Remarks
Position 1: For a positive value, " " (space) (20H), and for a negative value, "-" (2DH) is
in this position.
Positions 2 to 9: The absolute value. When the numerical value does not use all the 8 posi-
tions, the code for space is entered to each excessive position as shown in
this example.
Positions 10,11: One or two letters indicating the weighing unit. As shown in this example,
the code for space is entered at position No.11 if only one letter is used for
the unit.
Position 12: Code for delimiter.

(2) Information of additional bytes

(i) Output with stability information
When outputting data with stability information (Refer to 15.2.3 (4)-(i)), either of the following
characters is added in front of Character No.1 in the example. Consequently, the data
becomes 1 byte longer.
When stable: S
When unstable: U
(ii) Verified balance as a legal measuring instrument
The brackets “[ ]” bordering auxiliary indicating device of legal measuring instrument can also
be outputted. In this case, “[” and “]” are inserted according to their positions in the weighed
data. They come to the positions before and after Position No.9 in the example. Conse-
quently, the data becomes 2 bytes longer.
(iii) Unit expressed with three letters
Some weighing units are expressed with three letters. Therefore one more byte is inserted
after Position No.11 in the above example. Consequently, the data becomes 1 byte longer.

83
 15. Connecting Peripheral Instruments

(iv) When the delimiter “C/R+L/F” is selected (Menu item No. 96 . Refer to 15.3.7.)
The delimiter information requires one more character. Therefore one more byte is added
after Position No.12 in the above example. Consequently, the data becomes 1 byte longer.

(3) Data format in case of “oL” or “-oL” (Overload)

The below is the data format for “oL”.

15.2.3 Using Command Codes

Note
If communication conditions are incorrectly set, a communication error
message “ComErr” is displayed.

(1) Commands that end with a number, character, or symbol other than [=]: Transmit to the balance
with a delimiter for each command code.

Example 1: PRINT<CR> ... The same operation as pressing the [PRINT] key

(2) Commands that end with a [=]: Transmit the number to the balance with a delimiter.

Example 2: TIME=1234 <CR> .. 12:34 is set as the current time.

Example 3: P.TARE=1.23 <CR> (example of type of the second decimal place).

Read Chapter 7 Before Use of These Pages

...1.23g is set as a Pretare value.

Example 4: P.TARE=0.00 <CR> (example of the second decimal place)

...Clears (cancels) the Pretare value.

Note
Number of digits, decimal point, position of decimal point of the numeral
transmitted succeeding to ‘=’ are the same as the case of setting the
numeric value using the AKB-301 Application Keyboard.
Use the same number of decimal places as in the gram-display.
This restriction does not apply to USER=, SOLID=, and LIQUID=.

Example 5: MENU=4630 <CR> (4-digit number after [=])

This is the same in the following operation.
.. from mass display, press the [CAL] key five times, then press the [O/T] key
once and the press the [CAL] key six times. This returns to the same display
as if the [CAL] key was never pressed.
Press the [O/T] key once, then [CAL] key three times, and the [O/T] key
once more.
This example indicates that menu item 25 (Anti-vibration mode) is selected.

Notes
• If there is 0 in the four-digit number, the setting is complete at that point
and menu selection is ended.
• The result of this command varies depending on the type of the balance.

Example 6: #=2.56 <CR>

Example 7: #=12.345.67 <CR>

on the balance.
With the commands in Example 6 &7, [#2.56] and [#12.345.67] are displayed
on the balance. When the operator presses the [PRINT] key, the character
string '2-56<CR>' and '12-345-67<CR> are output from the balance.

(3) Echo back command

Read Chapter 7 Before Use of These Pages

The balance again transmits the character strings of N pieces included between an echo back
command ‘{‘ or ’}’ and the delimiter.
An unprocessed echo back command is not left in the receiving buffer of the balance, N ≤ 30.

Example 8: ABCDEFG12345<CR>
... After receiving this command, the balance outputs ABCDEFG12345<CR>.

15.2.4 Multi-Connection Mode

A maximum of 26 UW/UX series balances can be connected to one personal computer at the same
time. This is called “Multi-Connection mode.” To use the balance in this mode, prepare RS-232C
cables in the number of balances connected, and the optional IFB-102A RS-232C Interface.

Connecting Method
Example for connecting 10 units of UW/UX series balances to one personal computer is shown in the
diagram below.

Personal computer IFB IFB

UW or UX [j] UW or UX [i] UW or UX [a]

Assignment of Identification Name

In this example (10 balances connected to one computer), assign the identification name in lower-case
alphabets.
Since 10th character of alphabet is “j,” assign “j” to the balance closest to the personal computer, “i” to
next closest balance, and so on, back to “a.”

Setting to Multi-Connection Mode

1 Adjust the communication menu settings of all

the balances to the specification of the personal
computer, and then, turn off the power to all bal-
ances.

2 Start supplying the power to the whole system.

Wait until all balances display OFF.

3 Send “[α] <delimiter>” from the personal com-

puter.
α is the name of the balance next to the personal
computer. In the example above, lower-case “j.”
This command is valid only one time after turning
the power ON.
Respective balances automatically enter the
Multi-Connection mode and the mass is dis-
played.

90
 15. Connecting Peripheral Instruments

On this process, the name smaller than the sent

command by one, i.e. “[i] <delimiter>”, is returned.

4 This procedure completes the setting to the

Multi-Connection mode.

Only the commands shown below are valid in the Multi-Connection mode.
(α is the name of the balances.)
[α]TARE Same as the operation of pressing the [O/T] key of the balance “α”.
[α]T Same as the operation of pressing the [O/T] key of the balance “α”.
[α]POWER Same as the operation of pressing the [POWER] key of the balance “α”.
[α]Q Same as the operation of pressing the [POWER] key of the balance “α”.
[α] PRINT Same as the operation of pressing the [PRINT] key of the balance “α”.
[α]D05 Same as the operation of pressing the [PRINT] key of the balance “α”.

[α]CAL Same operation as sending the CAL command to the balance “α”.
[α]UNIT+ Same as the state of holding down the [UNIT] key of the balance “α”.

Format of Output Data from the Balance

The output data from the balance “α” is performed with the following format.
“[α]” data <delimiter>
Format of the load data is the same as the normal output form (Format EB type).
Operation is not guaranteed for the data containing characters, such as printing of date, time, and cali-
bration document etc.

91
 15. Connecting Peripheral Instruments

Restricted Items in the Multi-Connection Mode

• Multi-Connection mode is not designed for each balance to independently send the data.
This mode is for sampling the data by control of multiple balances with one PC. This is not the func-
tion to support multiple balances for sending the data separately.
When multiple number of data and commands exist on the system at the same time, the balance
may not operate normally. For example, multiple data may exist simultaneously on the system when
using multiple balances in the Application Measurement mode such as Auto Print or Continuous
Output, or pressing the [PRINT] key. Normal operation cannot be guaranteed.
• Peripheral instruments connected to the DATA I/O or IFB-102A connector, such as an EP-50 Elec-
tronic Printer, cannot be used.
• The communication formats can only be used with “Format EB type”. Delimiters cannot be used with
menu items 97 or 98 (setting for WindowsDirect).
• It will take an average 0.05×N seconds for the data from the personal computer to reach balance unit
N, even at setting of 38400 bps. Also, it will take almost the same time for the data from the balance
in the Nth position to reach the personal computer.

Cancellation of Multi-Connection mode

Multi-Connection mode cannot be canceled unless the power for all balances is turned OFF.

15.3 Communication Setting

15.3.1 Overview
This menu is used to set the specifications for communication between the balance and a personal
computer or electronic printer.

Notes
• This menu affects both the RS-232C and DATA I/O at the same time.
For the instrument to be connected to the DATA I/O connector such as
an electronic printer, select the communication setting of the balance to
the default settings, which are menu items 76 , 77 , 83 , 89 , 92 , 94 .
However, select WindowsDirect setting (6.2.1) and follow the manual of
the electronic printer when using EP-80 or EP-50WIN Electronic Printer

simultaneously with WindowsDirect.
• When WindowsDirect function is set by the procedure described in
6.2.1, the communication settings are the same as selecting menu items
74 , 77 , 81 , 89 , 92 , 97 .

15.3.2 Handshaking
Handshaking determines whether the peripheral equipment can receive communication data from the
balance. This function does not relay the status of the balance to the peripheral equipment.
The balance is able to receive as long as there is space in the receiving buffer of the balance. This
function operates once “oFF” is displayed, operation in other states is not guaranteed.
When the balance output is retained by handshaking, the display of the balance is locked. Determine
the specifications for handshaking.

To have software handshaking not performed, select menu item 73 .

To have software handshaking performed as the following, select menu item 74 .

After the balance receives X-OFF (13H), the balance output is retained.
After the balance receives X-ON (11H), the balance output is initiated.

To have hardware handshaking performed as the following, select menu item 75 .

When DTR is OFF, the output from the balance is retained.
When DTR is ON, the output from the balance is initiated.

To have timed hardware handshaking performed, select menu item 76 .

16. Maintenance and Transportation

16.1 Maintenance
Use a soft damp cloth containing a neutral detergent to clean the balance.
Avoid using organic solvents, chemicals, or dusting sprays as they may damage the coatings of the
balance or the display panel.
Attach the protective in-use cover (standard accessory) when the balance is used in an environment
where it is susceptible to being soiled.
The pan can be removed and washed with water. Verify that the pan is completely dry before replacing
it on the balance.

16.2 Moving the Balance

To carry the balance, hold the balance firmly with both hands.
To transport the balance, use the shipping carton used to deliver the balance.

For UW balances: Before placing the balance into the shipping carton, remove the pan and pan
supporter caps and verify that the transportation screws in the bottom of the
balance have been tightened clockwise until they stop. Refer to 4.3.
For UX balances: Remove the pan and pan supporter caps and place the balance in the packing
case as it was shipped.

Caution
Failing to tighten the transportation screws, placing the balance on its side
when turning the transportation screws, or failing to remove pan supporter
caps before placing the balance upside down may cause serious damage
to the mechanism.

Note
Using a verified balance as a legal measuring instrument in using region:
Span calibration must be newly performed with the built-in calibration
weight after the balance has been moved and re-installed.

A-6. Performance Checks

Not applicable to a verified balance as a legal measuring instrument in using region

Notes
• Performance checks should be conducted in a room where there are no
sudden temperature changes. Refer to the installation guidelines for the
environmental factors that assure optimal performance.
• The following is a standard method used to determine whether the bal-
ance is working properly.
• The specific criterion should be set according to each user’s quality goal.

Repeatability

1 Allow the balance to warm up sufficiently by

turning ON the power and leaving it at the gram-
display at least two hours before starting the per-
formance checks.

2 Choose a weight that is near half the capacity

of the balance. Load and unload the weight five
successive times and record the following items:
Xi: Displayed value when the weight is loaded.
Yi: Displayed value when the weight is unloaded.

3 Use the formulas shown below to calculate the

values Rx and Ry.

4 Balance repeatability is considered normal

when both Rx and Ry are within five counts.
* One count corresponds to one minimum dis-
play unit of the balance model.

Load and unload a weight which is

near the capacity of the balance five
successive times.

Load : X1, X2, .....Xi, .....X5

↑
↓
Unload : Y1, Y2, .....Yi, .....Y5

Rx = X (max) − X (min)
Ry = Y (max) − Y (min)

Cornerload Performance

1 Allow the balance to warm up sufficiently by

turning ON the power and leaving it at the gram-
display at least two hours before starting the per-
formance checks.

2 Use a weight that is approximately 1/4 of the

balance capacity and place it sequentially at five
5 4
different positions on the pan in the order shown.
1 Record the readings in each of the five positions.

2 3 3 If the difference between the readings at the

center position and each of the off-center posi-
tions (eccentric error) is within five counts, the
balance cornerload performance is considered
normal.
* One count corresponds to one minimum dis-
play unit of the balance model.
