Getting to know your comparator balance
In this Section you will be given basic information about your comparator balance. Please read right through this Section carefully
even if you already have experience with METTLER TOLEDO balances; please pay special attention to the safety warnings!
1.1
Introduction
Thank you for choosing a METTLER TOLEDO comparator balance.
To ensure that we can offer you personal service and provide you with the most efficient support, this product is accorded special
treatment: Not only complete installation of the balance, but also the instruction are handled by a specialist from your country who
has been specially trained on the appropriate balance. Adjustment work may be performed only by this specialist.
However, a top quality balance and optimal installation are not enough. To obtain the best possible measurement results, the
environment of the balance must be given careful attention. We recommend a basement room which is as free from vibrations as
possible and where the temperature and air humidity remain constant.
These Operating Instructions apply only to the AX12004 comparator balances. Please read these Operating Instructions carefully
right through so that you can derive maximum benefit from all the possibilities your comparator balance offers.
You will find instructions for using the “WeighCom” application for mass comparison, which is delivered with the comparator balance,
in the enclosed “WeighCom Application” Operating instructions.
The comparator balances combine a large number of weighing and adjustment possibilities with exceptionally convenient operation.
With these balances software updates can be downloaded from the Internet and loaded into the balance.
1.2
Introducing the AX12004 comparator balances
The following features are common to the AX12004 comparator balance:
– Built-in applications for mass comparison (“WeighCom”) as well as for normal weighing. Further applications can be downloaded
from the Internet onto your computer as required, and from there into the comparator balance.
– Integral RS232C interface.
– Touch-sensitive graphics terminal (“TouchScreen”) for easy, convenient operation.
– Two programmable sensors for hands-off operation (“SmartSens”) to speed up frequently recurring tasks.
1.3
Conventions and symbols used in these operating instructions
The following conventions apply throughout these operating instructions:
– The illustrations in these operating instructions are based on the AX12004 comparator balance.
– Key designations are indicated by double angular parentheses (e.g. «On/Off» or «4»).
These symbols indicate safety notes and hazard warnings which, if ignored, can cause
personal danger to the user, damage to the balance or other equipment, or malfunctioning of the balance.
This symbol indicates additional information and notes which make using your
comparator balance easier, and help you to use it correctly and efficiently.

Safety first
To ensure safe and trouble-free operation of your comparator balance, please observe the following instructions:
Read right through these operating instructions carefully, even if you already have experience with METTLER
TOLEDO balances. Always operate and use your comparator balance only in accordance with the instructions
contained in this manual.
The instructions for setting up your new comparator balance must be strictly observed.
The comparator balance may only be used in enclosed interior rooms. It is not permitted to use the balance
in hazardous environments.
Use only the AC adapters delivered with your balance, and check that the voltage printed on it is the same as
your local power supply voltage. Only plug the adapters into a socket which is grounded.
Do not use sharply pointed objects to operate the keyboard of your comparator balance!
Although comparator balance is very ruggedly constructed, it is nevertheless a precision instrument. Treat it
with corresponding care, and it will reward you with many years of trouble-free service.
Do not open the balance or the control unit: It does not contain any parts which can be maintained, repaired,
or replaced by the user. If you ever have problems with your comparator balance, contact your METTLER
TOLEDO dealer.
Use only balance accessories and peripheral devices from METTLER TOLEDO; they are optimally adapted to
your comparator balance.

2.3
Selecting a location
Your comparator balance is a precision instrument. Its accuracy and reliability depend on its being placed in an optimal location:
The surface on which the comparator balance stands should
• Transmit as few vibrations as possible,
• Not bend during the work,
• Be antimagnetic (no steel top),
• Be protected against static charging (not plastic or glass),
• Preferably be in a corner of the workroom, because the corners are the most rigid
points in a building with the least amount of vibration.
• Be reserved as the work place for the comparator balance.
The workroom should
• Be as insensitive as possible to shocks and vibrations,
• Have only one door (drafts),
• Have as few windows as possible (hazard due to direct sunlight),
• Be as free from drafts as possible (important with air conditioning systems).
30°
20°
10°
0°
Temperature
• The room temperature should be as constant as possible to avoid temperature drift
of the weighing result,
• Avoid weighing in the vicinity of radiators (temperature drifts, air currents).
Atmospheric humidity
• The relative humidity should be between 40 and 70 % (max. fluctuations: ±2 %).
Light
• Avoid direct sunlight (e.g. wall without window).
• Light fixtures should be at a sufficient distance from the balance to avoid disturbances
due to thermal radiation, particularly in the case of light bulbs. Fluorescent lamps are
less critical.
• Always leave the light switched on.
Setting up the comparator balance

Air
Avoid weighing,
• In the vicinity of air conditioning units or devices with fans (e.g. computers),
• Next to a door.
Leveling
The comparator balance is adjusted to be level when it is delivered. The air bubble must
always be in the inner circle of the level indicator.
If ever the air bubble is not in the inner circle of the level indicator, please contact the
METTLER TOLEDO distributor responsible for the comparator balance.
2.4
Location change
Before any location change, please contact the METTLER TOLEDO organization or our distributor.
2.5
Power supply
Your balance is delivered complete with an AC adapter and a country-specific power
supply cable. The AC adapter is suitable for all power supply voltages in the range:
100 – 250VAC, -10/+15%, 50 – 60Hz.

Operating the dial weights
The AX12004 has an electrical weighing range of 111 g. This is adapted to the respective weighing range by adding the corresponding
dial weights. The dial weights must be placed on the hanger by hand. To do this, proceed as follows:
– Turn the lever (6) upward. The window opens and any dial
weights which have already been added are lifted off the
hanger.
6
– Place the necessary dial weights (see table above) on the
hanger.
Caution: The hanger for the dial weights and the
weighing pan are mechanically interconnected and
must never bear a joint load of more than 12 kg
(dial weights + weight on the weighing pan =
12 kg, e.g. 2 kg + 10 kg).
– Turn the lever (6) downward. The window closes and the dial
weights are lowered onto the hanger.

the window again.
– Open the draft shield (2) by hand.
– Place the reference weight on the surface of the turntable (3).
Important! Place the reference weight as centrally as possible on the surface of the
turntable. This saves unnecessary centering operations.
– Turn the turntable through 180° with the lever (5). The reference weight is now over
the weighing pan.
– Place the test weight(s) on the (free) surface of the turntable (3).
Important! Place the test weight(s) as centrally as possible on the surface of the
turntable. This saves unnecessary centering operations.
– Close the draft shield (2) by hand.
– Center the reference weight. Turn the lever (4) to lower the reference weight onto
the weighing pan and wait until the weighing pan stops oscillating. Then turn the lever
(4) to raise the weight again. Repeat this operation until the weighing pan no longer
oscillates when the weight is placed on it, and the weight no longer changes its
position. With good prepositioning this should be possible in about 3 operations.
– Turn the lever (4) to raise the turntable and then turn the lever (5) to turn the turntable
through 180°. The test weight(s) is/are now over the weighing pan.

– Turn the lever (4) to lower the weight onto the weighing pan. Then press the «1»
key.
– As soon as the stability detector symbol (the small ring to the left of the weight
display) goes out, the display is stable and you can read the weighing result. In the
illustration at left, the stability detector symbol is still visible, and the weighing result
is therefore not yet stable.
– Turn the lever (4) to raise the reference weight from the weighing pan. Then turn the
lever (5) to turn the turntable through 180° and turn the lever (4) to lower the test
weight(s) onto the weighing pan.
– As soon as the stability detector symbol (the small ring to the left of the weight
display) goes out, the display is stable and you can read the weighing result. In the
illustration at the side, the stability detector symbol is still visible, and the weighing
result is therefore not yet stable.
– Test weight = reference weight + display value (conventional weighing values).
Note: If you are working with the “WeighCom” application, you will be guided through
the mass comparison procedure (see separate operating instructions for the “WeighCom”
application).

When this key is pressed, the weighing result is transmitted via the interface to, for example, a printer. However,
other devices, such as a PC, can also be connected. There are no restrictions on the data that can be
transmitted.
The keys in the dark field at the bottom edge of the terminal are for carrying out the weighings.
4.2
The display
The illuminated graphics display of your terminal is a “TouchScreen”, or in other words, a screen which is sensitive to touch. You
can use it not only to read data and settings, but by touching the display surface you can also make settings and carry out functions.

The display is divided into a number of zones:
1 In the upper left-hand corner, the currently active application and the current user
profile are displayed. By touching this zone, you can call up a menu in which
you can select the desired application (you can also call up this menu with the
«6» key).
2 In the top right-hand section, the date (2a) and time (2b) are displayed. By
touching these zones, you can change the date and time.
3 In this zone the current weighing result is displayed. If you touch this zone (3a),
a small menu appears in which you can select the font for displaying the
weighing result. If you touch the weighing unit (3b), a window opens in which
you can select the desired weighing unit.
4 This zone displays additional information (information fields), which make your
work easier. Touching this zone opens a menu in which you can specify which
information fields and function keys should be displayed (the same menu is also
available under the «7» key).
5 This zone displays the “SmartTrac”, which is a graphical weighing-in aid that
shows you at a glance how much of the weighing range has already been used
and how much is still available. By touching this zone, you can choose between
various different display styles for “SmartTrac”, turn it off completely, or include a
small stopwatch in the display.
6 This zone is reserved for the function keys, which give you direct access to frequently
used functions and settings. If more than 5 function keys are activated, you can use
the arrow keys to switch between them.
Basic operating concepts for the terminal and software
22
4.3
The software on your balance
The software controls all the functions of your balance. It also makes it possible to adapt the balance to your specific working
environment. Please read the following Sections carefully; they form the basis for operating your balance.
The software comprises the following levels:
– User profiles
– Applications
– Settings
User profiles
The purpose of user profiles is to adapt the balance and its applications to your personal way of working, or
to specific weighing tasks. A user profile is a collection of settings which you can define yourself and which
are available to you at a keystroke.
3
When the balance is switched on, it automatically loads the “Home” profile. The “Home” profile is a starting
point to which you can return at any time by touching the «3» key. Before leaving the factory it has been
programmed with standard settings which all users can work with.
4
As well as the “Home” profile, 8 other user profiles are available in which you can change the settings at will.
(Two of the user profiles have been programmed at the factory for very fast and very accurate weighings and
have been given the corresponding names “Fast” and “Accurate”). You can use the «4» key to call up the
desired user profile.
Note: The “Home” profile can be changed at will in the same way as the 8 other profiles. However, we
recommend you not to change the settings in the “Home” profile that were made at the factory, but to change
one of the other 8 user profiles instead.
Applications
6
Applications are software modules for carrying out specific weighing tasks. 2 applications are loaded
onto the balance before it leaves the factory (for normal weighing and comparative weighing “WeighCom”). When the balance is switched on, it starts the application for normal weighing. The other
applications can be accessed with the «6» key. You can also download additional applications from the
Internet if required (see Section 6).
Settings
The software differentiates between two sorts of settings:
7
– Application-dependent settings: The range of available settings differs depending on the application
selected. The multi-page menu for application-dependent settings can be accessed with the «7» key.
You will find information about the individual settings that are possible in the chapters relating to the
respective applications.
– System settings which are not application-dependent (e.g. the dialog language setting): The range of
available settings of this type is the same in all applications. To call up the system settings touch the
«7» or «6» key and then the “System” button. You will find information about the individual settings
that are possible in Section 5.
Both types of setting are assigned to the currently active user profile and stored with it.

5.3
Specifiying the weighing parameters
“Weighing mode”
You can use this setting to match the balance to the type of weighing. Select “Sensor
mode” weighing mode. This setting delivers a slightly filtered weighing signal and is
suitable for the used applications.
Note: “Universal”, “Dosing” and “Checkweighing” have no function on the AX12004
comparator balance.
Factory setting:
“Sensor mode”
“Environment”
You can use this setting to adapt the balance optimally to the environmental conditions
at the workplace. If you work in surroundings which are practically free from temperature
fluctuations, drafts, and vibrations, select “Very stable”. On the other hand, if you work
in surroundings where the conditions are constantly changing, select “Very unstable”.
In between these two settings there is a choice of three further settings.
Factory setting:
“Standard”
“Measurement release”
You can use this setting to specify how rapidly the balance considers the measurement
value to be stable and releases it. The “Very fast” setting is recommended if you require
rapid results and their repeatability is of secondary importance. The “Very reliable”
setting gives very good repeatibility of the measurement results, but lengthens the
stabilization time. In between these two settings there is a choice of three further settings.
Note: If you choose a setting other than “Reliable + fast”, a window appears with
additional information about the selected setting.
Factory setting:
“Reliable + fast”
System settings
26
“AutoZero”
This switches auto-zeroing (“AutoZero”) on and off. If auto-zeroing is switched on, the
balance continually corrects any zero point drift that may occur.
Factory setting:
5.4
“Off” (= switched off)
“SmartSens” settings
“SmartSens left”, “SmartSens right”
You can use this setting to define the function of the left-hand and right-hand
“SmartSens” sensors.

“Off”:
SmartSens is inactivated
“Door”:
Has no function on the AX12004 comparator balance.
“1”:
Resets the display to zero
“Print”:
Prints out (same function as the «8» key).
Factory setting:
“Off” (= switched off)
System settings
27
5.5
Renaming the user profile
“User Name”
Here you can change the name of the current user profile. Both large and small letters,
as well as figures, can be used for the name. The maximum length for the name is 20
characters. Use a name for the user profile that allows unambiguous identification.
Factory setting:
“Fast”, “Reliable”, “User X” (“X” = 3 – 8)
Note: At the factory, the first two user profiles have already been given settings for very
fast and very reliable weighing, respectively. So that this is immediately clear, these two
profiles have been given the names “Fast” and “reliable”.
“Language”
Here you can select the language in which you wish the balance to communicate.
Factory setting:
Depends on the language package which has been installed.
The factory setting is usually the language of the destination
country.
“Password”
Here you can specify the password for the current user profile. The password protects
the following areas of the current user profile:
– Access to the system settings
– Calling up the user profile.
If one of these areas is called up, the corresponding password must first be entered.
Note: If a password is defined for the “Home” profile, it only protects access to the system
settings.
The password consists of a sequence of up to 18 characters. You can use the “Clear”
button to delete the current password and thereby deactivate password protection. If no
password is specified, “no password” appears in the display.
Warning: Make a note of your password! If you forget it, contact your METTLER TOLEDO
dealer.
Factory setting:
No password

5.6
Selecting peripheral devices
Various peripheral devices can be connected to your balance. In this menu you can
specify which device should be connected. Important: In contrast to the other system
settings, these settings apply to all user profiles.
The following settings can be selected:
– “Printer”:
Printer
– “Host”:
External computer (bidirectional commounication: the
balance can send data to the PC and receive commands or data from it)
– “Feeder (LV11)”:
METTLER TOLEDO LV11 automatic feeder.
– “Secondary display”:
Secondary (auxiliary) display
– “Bar code”:
Bar code reader
– “AT cont. mode”:
Peripheral devices which use “AT Continuous Mode”.
The same settings are available for each of these devices. “Off” means that no device
of this type should be connected to the RS232C interface. “RS232 fixed” activates the
interface for the selected device. Important: You can only activate one single device
(“RS232 fixed”), all other devices must be deactivated (“Off”). If you activate another
device, the device that was formerly selected is automatically deactivated.
If you have activated a device, you can use the “Define” button to set the interface
parameters for communication with this device (baud rate, parity, handshake, end-ofline characters, and font). The parameters are preset for the correspondingly optimal
METTLER TOLEDO devices (for accessories and options, see Section 8).
Note: No interface parameters can be defined for the “Secondary display” setting: they
are preset to fixed values.
Factory setting:
“Host”
(9600 baud, 8 data bits/no parity, XON/XOFF protocol,
end-of-line characters <CR><LF> ANSI/WINDOWS-font)
Important: To enable correct printing of special characters (e.g. “°C”) on METTLER
TOLEDO printers, the balance and printer must both be set to 8 data bits.

Terminal settings
“Brightness”
Here you can set the brightness of the display. Touch the arrow buttons to adjust the
brightness in the range 0 % to 100 % as required. Each time one of the two arrow
buttons is touched, the brightness is instantly adjusted so that the change can be seen
immediately.
Factory setting:
80 %
Note: If the balance is not used for 15 minutes, the brightness of the display is
automatically reduced. This increases the life of the backlighting. The next time either
a key is touched or there is a change in weight, the brightness is changed back to the
value selected here.
“Contrast”
Sets the contrast of the display in the range 0 % to 100 %. Adjustment is done in the
same way as for brightness.
Factory setting:
50 %
“Font”
Selects the font for displaying the weighing result. There is a choice of 3 fonts.
Note: You can also make this adjustment directly in weighing mode by touching the
weighing result. A window appears in which you can select the font directly.
Factory setting:
Round letters (first setting at top of list)
“Beep”
Sets the volume of the beep in the range 0 % to 100 %. Setting to 0 % switches the beep
off. To make the setting, there is a sliding adjuster similar to those for setting the
brightness and contrast.
Factory setting:
75 %
System settings
30
“Touch Function”
If you switch off the touch function for the “Touch Screen”, the display no longer responds
to touch in weighing mode, and so you can no longer make settings by touching the
display (exception: function keys). Important: In setting mode the touch function is
always active, because otherwise you can no longer make any settings.
Factory setting:
“On”
“Touch adjustment”
If you have the impression that the balance no longer reacts correctly, you can adjust
the “Touch Screen” by touching a certain point of the display. When you touch the
“Activate” key a window appears and you are prompted to touch the flashing surface.
This operation can be repeated several times. (It can be terminated at any time with the
“C” key.)
5.8
Resetting to the factory settings
Here you can reset all the settings to the factory settings. Important: Resetting affects
all the settings (application-dependent settings and system settings) for the active
user profile!
If you select “Set”, for safety reasons you will be asked whether you really want to reset
to the factory settings. Select either “OK” to reset to the factory settings or “C” to keep the
existing settings.

5.9
Date and time
Important: In contrast to the other system settings, the settings for date and
time apply to all user profiles!
“Date Format” (for the display)
The following date formats are available:
“D.MMM.YYYY” Example:
3. APR. 2001
“MMM D YYYY” Example:
APR 3 2001
“DD.MM.YYYY” Example:
03.04.2001

“Time”
Sets the current time. Enter the current time in 24-hour format (hh.mm.ss), irrespective
of the time format you selected for the display. The input window is the same as for the
date, except that there are two additional buttons “+1H” and “–1H” which can be used
to put the time forward or back by one hour respectively. This makes it possible to
change over quickly to summer time or winter (standard) time. Note: You can also set
the time directly in weighing mode by touching the time in the display.
System settings

5.10
Energy-saving function and battery change date
“Standby”
Here you can specify how long the balance can remain unused before it switches over
to “Standby” mode. “Standby” mode is the same status as when the balance is switched
off with the «On/Off» key. To switch the balance on again, the «On/Off» key has to be
pressed.
Factory setting: “Off” (“Standby” mode deactivated)
Note: Irrespective of the setting for “Standby” mode, the brightness of the display is
automatically reduced if the balance is not used for 15 minutes. This increases the life
of the backlighting. The next time either a key is touched or there is a change in weight,
the brightness is automatically changed back to the value selected here.
“Battery change”
Your balance has a memory which is protected by a battery so that all the settings are
saved even if the balance is disconnected from the power supply. The average service
life of the battery is about 5 years. The battery can only be changed by a service
technician. After the battery has been changed, the service technician enters the date for
the next battery change. When this date is reached, the battery symbol appears under
the time display in weighing mode to remind you that the battery should be replaced.
You cannot make any changes in this field: You can only check the date when the next
battery change is due.

5.11
Balance information
“Balance ID”
Here you can assign an identification to the balance (up to a maximum of 20
characters). This can be used, for example, to identify the balance within a network. The
balance identification is also printed out on adjustment records and weighing reports.
This makes it possible to link the records and reports to a specific balance.
Factory identification: No balance identification
Important: Unlike other system settings, the balance ID applies for all user profiles!
“Balance information”
This window displays important information about your balance, such as balance type,
serial number, etc. You should always have this information ready when you contact
your METTLER TOLEDO authorized representative. The date for the next service is also
displayed.

continuously developed further and improved. To make it as easy as possible for you as our customer to gain rapid benefit from these
further developments METTLER TOLEDO provides the latest versions on the Internet. The software available on the Internet has been
developed and tested by Mettler-Toledo GmbH in processes which comply with the guidelines of ISO 9001. However, Mettler-Toledo
GmbH accepts no responsibility for any consequences of using this software.
6.1
Operating principle
You will find full information about your balance together with updates on the METTLER TOLEDO website at the following address:
www.mt.com/ax
We recommend you to put a bookmark in your web browser at this address so that in the future you can go direct to this Internet
website.
The full packages contain not only applications but also the balance program. If the selected package contains an application which
is not yet described in these operating instructions (or which has since been updated) you can also download the corresponding
instructions in Adobe Acrobat® PDF format. To open PDF documents you need Adobe Acrobat Reader® which is already installed on
many computers. If it is not installed on your computer, you can download this program free of charge from the Internet (e.g. from
www.adobe.com).
Together with the application package the so-called e-Loader will also be loaded onto your computer. You can use this program to
transfer the applications from your computer onto your balance. The e-Loader can also be used to backup you balance settings before
the new application package is transferred to the balance. When the application has been transferred, you can reload the backedup settings onto the balance.
In the Sections that follow below you will find detailed information about downloading application packages from the Internet and
transferring the applications from you computer to the balance.
6.2
Prerequisites
To be able to download applications from the Internet and then onto your balance you need the following:
– PC with Microsoft Windows® operating system (version 95, 98, NT 4.0, or 2000)
– Internet connection and web browser
– computer-to-balance connection cable (RS232 cable, 9-pin sub-D plug m/f, order number 11101051)
6.3
Downloading the application package from the Internet
In a first step you must download the software from the Internet onto your computer as follows:
Connect your computer to the Internet.
In your browser select the Internet address www.mt.com/ax and then click on the “Software” link.

6.4
Loading the application package onto your balance
After you have downloaded the application package from the Internet, before you can transfer it to your balance you must connect
the balance to the serial interface of your computer with the RS232 cable. Note: If your balance also has additional optional interfaces,
take care that the cable is always connected to the RS232C interface installed as standard!
Set the interface on the balance to the following values (you will find detailed information about these settings in Section 4.6): for
peripheral device select “Host”, then set the following communication parameters: baud rate 9600; parity 8 bit/none; handshake
none; end-of-line <CR><LF>.
Check that the corresponding communication parameters on your computer are set to the same values.
Start the e-LoaderVXXX installation program you have downloaded from the Internet (“XXX” represents the version number). This
program installs the e-Loader on your computer.
Follow the step-by-step instructions which guide you through the installation.
When the installation is complete, the e-Loader starts automatically. The illustration at
left shows the startup screen of the e-Loader.
Before you update the softare on your balance, you should select the dialog language
and check the settings described below.
Select the language in which you wish to be guided through the updating process. The
e-Loader will display all the instructions and infomation in the dialog language you
select.
Select the interface of the computer to which the balance is connected.
Use the “Help” menu to check that the communication with the balance is functioning
(in the example at left, the e-Loader is confirming that a balance is connected).
If the e-Loader indicates that no balance is connected, first check that the correct
interface has been selected and then, if necessary, that the communication settings on
the computer and on the balance are correct and identical.

36
When you have made the necessary settings and checked the connection, you can start
the updating process. You do this by clicking on “Start Software Update Procedure”.
Follow the instructions of the e-Loader which will guide you through the updating
procedure step by step. The e-Loader will ask you whether you wish to backup the
current balance settings onto your computer. We recommend you to make this backup.
It saves you having to input all your settings again by hand, because during the updating
process they will be reset to the factory settings. When the updating process is complete,
the e-Loader asks whether you wish to restore the backed-up data onto the balance.
When the updating process is complete, you can close the e-Loader. Your balance now
functions with the newly loaded software.
6.5
Backing up and restoring your balance settings
As well as updating the balance software, the e-Loader also has a data backup feature which can be used to make a backup copy
of the current balance settings on a computer. If you use this you always have a backup copy of your settings which you can restore
onto your balance any time you need it. This feature can also be used to copy the settings from one balance to another.
To backup the current settings from a balance onto a computer, start the e-Loader and
call up the data backup function as shown in the illustration at left.
The dialog at left prompts you to confirm the data backup and to change the path for
saving the backup file if necessary.
To restore the balance settings from the computer to the balance, call up the restore
function as shown in the illustration at left.
When you have started the restore function, you can use the “Browse” button to select
the settings file -to be transferred to the balance. Remember that when you do this, all
the current settings in the balance will be overwritten!

Further important information
7.1
Error messages occurring during normal operation
Most error messages appear in plain text directly in the respective application, and usually accompanied by a text describing how
to correct the error. Error messages of this type are self-explanatory and therefore not mentioned below.
The following two error messages can appear instead of the weighing result:
Overload
The weight on the pan exceeds the weighing capacity of the balance. Reduce the weight
on the weighing pan.
Underload
Ensure that the weighing pan is correctly in place, can move freely, and does not catch
on the draft cover.
Error when switching on (weight display flashes)
When the balance was switched on (i.e. when it was connected to the power supply
or switched on from standby mode) one or more limits were exceeded. The usual reason
for this message to appear is when there is a weight on the weighing pan when the
balance is switched on. Remove the weight.
Taring or zeroing was interrupted by touching the «On/Off» key
Taring or zeroing was interrupted by touching the «On/Off» key. The message is
automatically extinguished after 3 seconds. Following this, tare/zero again.
7.2
Further error messages
During normal operation, the following error messages should not occur. If the message re-appears after switching the balance off
and on again, please contact the customer service department of your dealer.
“ERROR 4”
Cause:
EAROM error
Occurs:
When switching on (connecting to the power supply or switching on from standby mode)
Correction:
Switch balance off and on again. If the message re-appears, notify customer services.
“ERROR 6”
Cause:
No primary calibration
Occurs:
When connecting the balance to the power supply
Correction:
Notify customer services.
Further important information

7.3
Cleaning and service
It must be ensured that only clean, dust-free weights are used. In particular, the area occupied by the weights must be checked for
freedom from dust and if need be cleaned using a brush. The sliding doors of the balance should be opened only for changing the
weights.
Weighing pan, hanger, dial weights and the entire weighing chamber can also be cleaned using a soft brush.
Your balance is made from high quality, resistant materials and can therefore be cleaned with a commercially
available, mild cleaning agent. Observe the following instructions:
– Never use cleaning agents containing solvents or abrasives – this can cause damage to the foil cover
of the terminal and the glass cover of the display!
– Take care that no liquids penetrate into the balance, the control unit, the terminal, or the AC adapter!
– Never open the balance, the terminal, the control unit, or the AC adapter: they do not contain any components
that can be cleaned, repaired, or replaced by the user!
Ask your METTLER TOLEDO dealer about servicing possibilities – regular servicing by an authorized service
technician guarantees consistent weighing accuracy for years and prolongs the service life of your mass
comparator.

MT-SICS Interface commands and functions
Many of the balances and scales used have to be capable of integration in a complex computer or data acquisition system.
To enable you to integrate balances in your system in a simple manner and utilize their capabilities to the full, most balance functions
are also available as appropriate commands via the data interface.
All new METTLER TOLEDO balances launched on the market support the standardized command set “METTLER TOLEDO Standard
Interface Command Set” (MT-SICS). The commands available depend on the functionality of the balance.
Basic information on data interchange with the balance
The balance receives commands from the system and acknowledges the command with an appropriate response.
Command formats
Commands sent to the balance comprise one or more characters of the ASCII character set. Here, the following must be noted:
• Enter commands only in uppercase.
• The possible parameters of the command must be separated from one another and from the command name by a space (ASCII
32 dec., in this description represented as / ).
• The possible input for “text” is a sequence of characters of the 8-bit ASCII character set from 32 dec to 255 dec.
• Each command must be closed by CRLF (ASCII 13 dec., 10 dec.).
The characters CRLF, which can be inputted using the Enter or Return key of most entry keypads, are not listed in this description, but
it is essential they be included for communication with the balance.
Example
S – Send stable weight value
Command
S
Send the current stable net weight value.
Response
/ WeightValue/
/ Unit
S/
/ S/
Current stable weight value in unit actually set under unit 1.
S/
/I
