Chapter 1: Getting to know your balance
1 Getting to know your balance
In this chapter you will be given basic information about your balance. Please read right through this chapter 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 balance.
The analytical balances of the AX line, and the micro and ultra-microbalances of the MX and UMX lines, combine a large number
of weighing and adjustment possibilities with exceptionally convenient operation. With these new-generation balances additional
applications and software updates can be downloaded from the Internet and loaded into the balance.
Please read right through these operating instructions carefully so that you can fully utilize all the possibilities your balance offers.
These operating instructions apply to all balances in the AX and MX/UMX lines. However, the different models have different
characteristics regarding equipment and performance. Special notes in the text indicate where this makes a difference to operation.
1.2 Introducing the AX and MX/UMX balances
9
The AX and MX/UMX family of balances comprises a range of analytical, micro, and ultra-microbalances which differ from each other
in relation to their weighing range, resolution, and equipment.
The following features are common to all models of the AX and MX/UMX lines:
– Glass draft shield with motorized opening for precise weighing even in unstable environments.
– Fully automatic adjustment (calibration and linearization) using internal weight.
– Integrated applications for normal weighings, piece counting, percent weighing, and density determination. If required, further
applications can be downloaded from the Internet onto your computer and from there onto your 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.
Now a few comments on standards, directives, and quality assurance methods. The AX and MX/UMX balances conform to the usual
standards and directives. They support standard procedures, specifications, working methods, and records according to GLP (Good
Laboratory Practice) and SOP (Standard Operating Procedure). In this connection, records of working procedures and adjustments
become very important; for this purpose we recommend you to use a printer from the METTLER TOLEDO range, since these are
optimally adapted to your balance. The AX and MX/UMX balances have a CE Declaration of Conformity, and METTLER TOLEDO is
certified as manufacturer according to ISO 9001.
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 AX balances. Some of the menus and reports for the MX
and UMX balances may be slightly different. If this makes a difference to operation, this is described in the text.
– Key designations are indicated by double angular parentheses (e.g. «On/Off» or «4»).
Chapter 1: Getting to know your balance
10
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 balance
easier, and help you to use it correctly and efficiently.
1.4 Safety first
To ensure safe and trouble-free operation of your 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 balance only
in accordance with the instructions contained in this manual.
The instructions for setting up your new balance must be strictly observed.
The balance may only be used in enclosed interior rooms. It is not permitted to use the
balance in hazardous environments.
Use only the AC adapter delivered with your balance, and check that the voltage printed
on it is the same as your local power supply voltage. Only plug the adapter into a socket
which is grounded.
Take care when working with toxic or radioactive substances: the automatic door
function of your balance may cause the doors to close suddenly while the balance is
being loaded and inatentiveness when this happens can cause weighing substances
to be spilt. To prevent this, if you are working with hazardous materials, switch the
automatic door function and the two “SmartSens” sensors off (see Chapter 5).
Do not use sharply pointed objects to operate the keyboard of your balance!
Although your 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: it does not contain any parts which can be maintained,
repaired, or replaced by the user. If you ever have problems with your balance, contact
your METTLER TOLEDO dealer.
Use only balance accessories and peripheral devices from METTLER TOLEDO; they are
optimally adapted to your balance.
Chapter 2: Setting up the balance

2 Setting up the balance
This chapter explains how to unpack your new balance, and how to set it up and prepare it for operation. When you have carried
out the steps described in this chapter, your balance is ready for operation.
2.1 Unpacking and checking the delivered items
When you receive the balance, please check that all parts have been delivered.
Open the packaging and carefully remove all the parts. The standard delivery comprises
the following items:
– AX balances: fully-assembled balance wtih terminal installed
MX/UMX balances: weighing cell and control unit with terminal installed
– AX balances: weighing pan and draft cover; MX/UMX balances: weighing pan is
installed, draft disk is delivered separately and must be installed by the user.
– AC adapter with country-specific power cable
– Connection cable for connecting the weighing cell to the control unit (MX/UMX
balances only)
– Protective cover for the terminal
– Cleaning brush
– Cleaning tweezers (MX/UMX models only)
– Weighing tweezers (not for all models)
– Production certificate
– Operating instructions (this document)
– Booklet "Weighing the right way with METTLER TOLEDO"
– Instructions for the “METTLER TOLEDO Standard Interface Command Set” (MT-SICS),
in English
Please keep all parts of the packaging. This packaging provides the best guarantee of
protection when transporting your balance (Chapter 2.7).
2.2 Preparatory tasks
The AX, MX, and UMX balances have different weighing pans and draft covers. Please observe the following instructions for installing
these parts:
AX balances: First place the draft cover in position. The small drilled hole must face to the back so that the projection on the balance
fits into the hole. The weighing pan has two notches. Place the weighing pan into position so that the notches point toward the glass
doors. If necessary, turn the weighing pan slightly until it slides down into the correct position.
MX/UMX balances: install the draft disk. The draft disk for the UMX balances comprises several parts. To install, follow the
instructions printed on the packaging of these parts.
Use the cable delivered with MX and UMX balances to connect the balance to the control unit and the weighing cell. It does not matter
which end of the cable you connect to the control unit or the weighing cell. The screws of the cable plug have drilled holes and can
be sealed to prevent the control unit and weighing cell from becoming separated.
Chapter 2: Setting up the balance
12
2.3 Selecting a location and leveling the balance
Your balance is a precision instrument. Its accuracy and reliability depend on its being placed in an optimal location:
Choose a position which is stable, free from vibration, and as nearly horizontal as
possible. The supporting surface must be able to bear the weight of the fully loaded
balance safely. A stone table is recommended for MX/UMX balances.
Pay attention to the environmental conditions (see technical data).
Avoid:
– Direct sunlight
– Strong drafts (e.g. from fans or air conditioning)
– Excessive fluctuations in temperature.
Level the balance: Turn the two leveling screws at the back of the balance housing until
the air bubble of the level indicator is in the inner circle.
2.4 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 – 250 VAC, -10/+15%, 50 – 60 Hz.
Check that the local power supply voltage is in this range. If it is not, DO NOT connect
the balance or the AC adapter to the power supply, and contact your METTLER
TOLEDO dealer.
AX balances:
Plug the AC adapter into the socket in the back of your balance (see illustration) and
into the power supply.
MX/UMX balances:
Plug the AC adapter into the socket in the back of your control unit and into the power
supply (not illustrated).
Important: Guide the cables so that they cannot become damaged and will not be
in your way during your daily work! Take care that the AC adapter cannot come into
contact with liquids!
After the balance has been connected to the power supply, it carries out a self test and
is then ready for operation.
Chapter 2: Setting up the balance
13
2.5 Glass draft shield
The glass draft shield of your balance can be adapted to the environmental conditions and your weighing style, as well as to the
type of weighing and loading.
Draft shield on AX balances
The position of the coupling elements determines which parts (left-hand, right-hand,
and upper door) of the glass draft shield can be opened.
Try out various different combinations by moving the 4 coupling elements up and down.
We recommend arranging the glass draft shield in such a way that only those parts are
opened that are necessary for loading. Your balance then works faster, because the
disruptive air currents are weaker than when the glass draft shield is completely open.
The doors of the glass draft shield can be opened and closed either by means of the «2»
key, the “SmartSens” sensors, or by hand (this will be described in detail later in these
operating instructions).
Note: To open the doors by hand, the two lower coupling elements must always be
uncoupled (upper position)!
Draft shield on MX/UMX balances
The glass draft shield can be opened and closed either by means of the «2» key, the
“SmartSens” sensors, or by turning the door handle by hand. The door keys and
“SmartSens” sensors will be described in detail later in these operating instructions.
Note: The «2» key and the “SmartSens” sensor on the left-hand side of the terminal open
the draft shield for loading the balance from the right-hand side, whereas the «2» key
and the right-hand “SmartSens” sensor open the left-hand part of the draft shield.
Chapter 2: Setting up the balance

2.6 Adjusting the reading angle and positioning the terminal
So that you can work without fatigue, the reading angle of the terminal can be adjusted. For delivery, the terminal is fastened to the
balance or control unit. So that you can arrange your workplace optimally, the terminal can be disconnected from the balance or
control unit and positioned separately.
Adjusting the reading angle
If you wish to have a steeper reading angle, grasp the back of the terminal and pull it
slowly upward until it clicks into the desired position. Three different setting positions
are provided.
If you wish to have a flatter reading angle, press the two stop buttons on the back of the
terminal and press the terminal downward. Release the two stop buttons and the
terminal will then click into the desired position.
Removing the terminal from the balance
Switch off the balance.
Fold the terminal upward aginst the front panel of the glass draft shield. Note: to do this,
the terminal must be in the lowest setting position (flattest reading angle).
Unscrew the knurled screw underneath the terminal and remove the cover.
Chapter 2: Setting up the balance
15
Pull the connecting cable gently out of the tension relievers. Unwind the cable. Replace
the cover and fasten it with the knurled screw.
Fold the terminal forward again into its normal position.
Grasp the back of the terminal and pull it slowly upward until it clicks into the top position
(steepest reading angle).
Press the two stop buttons on the back of the terminal and pull the terminal further
upward. By doing this you release the two feet of the terminal from their mountings.
Place the terminal in the desired location. Press the two stop buttons and lower the feet
back into the terminal.
To fasten the terminal onto the balance or control unit again, carry out the procedure in
the reverse order. Please refer to the illustration on the left: it shows how to place the
cable correctly in the terminal housing.
2.7 Transporting the balance
If you wish to move your balance over a short distance to a new location, proceed as
follows:
AX balances
Switch off the balance and unplug the cable of the AC adapter, and any interface cables,
from the balance.
Fold the terminal upward.
Grasp the underside of the balance at the front (not the terminal!). On the back of the
balance there is a recessed handhold. Carefully lift the balance and carry it to its new
location. (Observe the notes in Chapter 2.3 regarding the choice of an optimal location).
Never lift the balance by the glass draft shield, as this can cause damage!
Chapter 2: Setting up the balance
16
MX/UMX balances
Switch off the balance and unplug the cable of the AC adaptor, and any interface cables,
from the control unit. It is not necessary to disconnect the control unit from the weighing
cell.
Grasp the control unit and weighing cell by the sides of the housing and carry them to
their new location (observe the notes in Chapter 2.3 regarding the choice of an optimal
location).
Never lift the balance by the glass draft shield, as this can cause damage!
Transporting over long distances
If you wish to transport or ship your balance over long distances, or if it is not certain
that the balance will be tranported in a vertical position, use the complete original
packaging (internal and external packaging). For the AX balance, observe the packing
instructions which are printed on the original packaging!
2.8 Below-the-balance weighing
So that weighings can be carried out below the working surface (below-the-balance weighing), your balance is provided with a
special hanger.
AX balances
Switch off the balance and unplug the cable of the AC adapter from the back of the
balance. Also remove any interface cables. Open the glass draft shield and remove the
weighing pan and the draft cover.
Carefully tip the balance toward the back so that it comes to rest on its back.
Unscrew the screw of the cover of the hanger and remove the cover.
The balance is now ready for installing the feedthrough for below-the-balance weighing.
MX/UMX balances
Remove the glass cover, the weighing pan, and the draft disk (which on the UMX
balance is made of several parts). Remove the draft shield from the unit.
Carefully tip the weighing cell toward the back.
Turn the cover plates of the hanger for below-the-balance weighing until the drilled hole/
ring for the feedthrough for below-the-balance weighing is exposed.
The balance is now ready for installing the feedthrough for below-the balance weighing.
Chapter 3: Simple weighing
17
3 Your first weighing
In this chapter you will get to know the operating and display elements of your balance which are necessary to carry out simple
weighings. This chapter provides a first introduction to operating your balance.
3.1 Switching the balance on and off
To switch the balance on: Briefly touch the «On/Off» key. After the balance has been
On
Off
switched on, it carries out a short test and is then ready for weighing.
When the balance is switched on for the first time, the indicator shown at the side
appears.
On
To switch the balance off: Touch the «On/Off» key and press it until “OFF” appears in
the display. The display then goes off, and the balance is switched off.
Off
3.2 Carrying out a simple weighing
To carry out a simple weighing, you need only use the keys in the lower, dark part of the terminal.
Open the glass draft shield either by hand or by touching one of the two «2» keys. Note:
On the MX/UMX balances the «2» key on the left-hand side of the terminal opens the right-
2
1
hand side of the draft shield, whereas the right-hand «2» key opens the draft shield on
the left-hand side.
If you work with a weighing container, place it on the weighing pan and then touch the
«1» key to tare the balance and set the display to zero. The glass draft shield
closes automatically and then opens again when taring is complete.
Place the sample to be weighed on the weighing pan, and close the draft shield (either
manually or using one of the «2» keys).
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.

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.
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
3
programmed with standard settings which all users can work with.
4
Applications
6
Settings
7
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 are software modules for carrying out specific weighing tasks. A number of applications are
loaded onto the balance before it leaves the factory (e.g. for normal weighing, percent weighing, piece
counting, and density determination). When the balance is switched on, it starts the application for normal
weighing. The other applications can be accessed with the «6» key. You will find instructions for working with
the standard applications in Chapter 6 and subsequent chapters. You can also download additional
applications from the Internet if required (see Chapter 10).
The software differentiates between two sorts of settings:
– 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 Chapter 5.
Both types of setting are assigned to the currently active user profile and stored with it.

5.3.4 Defining an external adjustment weight
If you work with an external adjustment weight, you can define its weight and unit here.
(Note: Depending on country-specific regulations, this function may not be available
for certified balances). An input window appears which looks like a pocket calculator
and can be used like one. Enter the weight of the external adjustment weight. Check the
weighing unit: it is shown to the right of the weight. If you touch the weighing unit, the
selection of available units appears.
Note: The units are not automatically converted, i.e. once you have input a value in a
particular unit, this value is unchanged, even if you change the weighing unit.
Factory setting: Depends on model
5.3.5 Defining an external test weight
If you work with an external weight to check the adjustment, you can define its weight
and unit here. The same input window appears as for the external adjustment weight.
Factory setting: Depends on model
5.3.6 Entering the weight certificate designation
Adjustment weights are generally delivered with a certificate. You can enter the
designation and/or number of the certificate delivered with the weight here (max. 20
characters). This makes it possible to unambiguously link the adjustment weight used
to a specific certificate. The certificate designation is then printed out on the adjustment
record. The input window allows input of alphanumeric characters.
Factory setting: None
5.3.7 Defining the weight identification
Here you can assign a designation to the adjustment weight used (max. 20 characters). This makes identifying the adjustment weight easier. The weight identification is
then printed on the adjustment report. The same alphanumeric input window appears
as for the certificate designation.
Factory setting: None
5.4 Specifiying the weighing parameters
“Weighing mode”
You can use this setting to match the balance to the type of weighing. Select weighing
mode “Normal” for all normal weighing processes, or “Dosing” for dispensing liquid or
powdery weighing samples. With this setting the balance responds very quickly to
minutest changes in weight. The “Hi-Resolution” setting is not available on all balances.
It is suitable for weighing procedures where highest possible precision is required, and
speed of weighing is of secondary importance (e.g. when weighing with comparator
balances). When the “Absolute weighing” setting is used, the balance only responds
to large changes in weight, and the weighing result is very stable.
Factory setting: “Normal”
Chapter 5: System settings
29
“Weighing quality”
You can use this setting to specify whether speed or precision of weighing has first
priority. If it is most important to have the result available rapidly, select “Very fast”. On
the other hand, if weighing accuracy has first priority, select “Very accurate”. In between,
3 other settings are available.
Factory setting: “Universal”
“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: “On” (= switched on)
Chapter 5: System settings
30
5.5 “SmartSens” settings
1
“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”: Opens/closes the glass draft shield (on MX/UMX balances you can also
choose whether the draft shield should open to the left or right).
–“1”:Resets the display to zero
Factory setting: “Door” (for both sensors)
Note: In setting mode (menus), SmartSens is always inactivated.
5.6 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”, “Acurate”, “User X” (“X” = 3 – 8)
Note: At the factory, the first two user profiles have already been given settings for very
fast and very accurate weighing, respectively. So that this is immediately clear, these
two profiles have been given the names “Fast” and “Accurate”.
5.7 Selecting the door function
“Door Function”
The automatic door function eases your work by making the doors of the glass draft
shield open or close automatically whenever specific functions require them to do so.
For example, the glass draft shield opens automatically after zeroing or taring, and
prompts you to put the material for weighing, or the tare weight, onto the weighing pan.
The door function is also activated during adjustment with an external weight, and when
checking this, or when carrying out series weighings. If you prefer to operate the glass
draft shield by using the «2» key, or the “SmartSens” sensors, or by hand, you can
deactivate the automatic door function.
Factory setting: “Automatic”

5.8 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
–“Secondary display”: Secondary (auxiliary) display
–“Bar code”: Bar code reader
balance can send data to the PC and receive commands
or data from it)
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 Chapter 12).
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: When connecting a METTLER-TOLEDO printer, the “IBM/DOS” character set
must be selected, so that special characters (e.g. “ºC”) can be correctly printed.

“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%
“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”
Chapter 5: System settings

irrespective of which date format you selected for the display.
Note: You can also make this adjustment directly in weighing mode by touching the
date. A window appears in which you can enter the date directly.
“Time Format” (for the display)
Here you can specify the format to be used for displaying the time. The following time
formats are available:
“24:MM” Example: 15:04
“12:MM” Example: 3:04 PM
“24.MM” Example: 15.04
“12.MM” Example: 3.04 PM
Factory setting: “24:MM”
“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.
5.12 Selecting the dialog language
Here you can select the language in which you wish the balance to communicate.

“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 10 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
“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
5.14 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)
Chapter 5: System settings
37
“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.

6.2.2 Select function keys
Function keys make it possible for you to access certain functions and settings of the application directly. The function keys are
displayed within the application at the bottom edge of the display (see Section 4.2). Touching a key initiates the corresponding
function.
In this menu you specify which function keys should be available in the application. You can call up the menu for the function keys
directly from the application by touching the corresponding zone in the display (Section 4.2).
The function keys are displayed in the application with a number. The numbers determine the sequence of the function keys in the
display. If you activate or deactivate a function key by touching it, the sequence of the keys is automatically updated. To specify a
completely new sequence, first deactivate all the function keys and then activate them in the desired sequence. You can use “STD”
to reset to the factory settings. Touch “OK” to save the changes (or touch “C” to quit the input window without saving the changes).
The following function keys are available:
“Adjust.int” and “Adjust.ext”: Adjusts the balance using an internal or external adjustment weight. You will find
instructions for making and recording the adjustment in Section 6.4.
“Test int” and “Test ext”: Checks the balance adjustment using an internal or external test weight. You will find
instructions for carrying out the checks in Section 6.4.
“PreTare”: Numeric input of a fixed tare value (tare preset). You will find information about
entering the tare value in Section 6.3.1.
“ID1”, “ID2” and “ID3”: Input of identifications (descriptive texts) for individual weighing procedures. Note:
Instead of “ID1”, “ID2”, and “ID3”, the specified designations appear (Section
6.2.10). You will find infromation about working with identifications in Section
6.3.6).
“1/10d”, “1/100d” and “1/1000d”: You can use these function keys to change the resolution of the weighing result
(Section 6.3.2).
“Nominal”: You can use this function key to specify the desired target weight (Section 6.3.3).
“–Tol” and “+Tol”: You can use these function keys to specify the accuracy (tolerances) with which you
wish to weigh in (Section 6.3.3).
“M+”, “CL Last”, “CL Sum” and “Result”: These function keys allow you to use the statistics (Section 6.3.5).
Factory setting: “Adjust. int” and “1/10d” activated.
Chapter 6: The “Weighing” application
41
6.2.3 “SmartTrac” and stopwatch
“SmartTrac” is a graphical weighing-in aid which makes it easier for you to weigh in to a specified target value. “SmartTrac” appears
in the application at the right-hand side of the display below the weighing result (Section 4.2).
In this menu you can select the display mode for “SmartTrac” or switch it off. Instead
of “SmartTrac”, you can also display a stopwatch.
Note: You can also call up this menu directly from the application by touching the
corresponding zone of the display (Section 4.2).
Factory setting: “SmartTrac” 1 switched on
You will find information about the various “SmartTracs” and the stopwatch in Section
6.3.4.
6.2.4 Selecting information fields
The information fields keep you constantly informed about the setting values, results obtained, etc. The information fields are
displayed in the application below the weighing result (Section 4.2).
In this menu you specify which information fields should be displayed in the application. You can call up the menu for the information
fields directly from the application by touching the corresponding zone of the display (Section 4.2).
The numbered information fields are displayed in the application. The numbers determine the sequence of the information fields in
the display. Important: For reasons of space, only a maximum of 4 of the available information fields can be displayed. If you activate
more than 4 information fields, only the first 4 are shown in the display. When you touch an information field to activate or deactivate
it, the fields are automatically resequenced. To specify a completely new sequence, first deactivate all the information fields and then
activate them in the desired sequence. You can use “STD” to reset to the factory settings, or touch “C” to quit the input window without
saving the changes. If you wish to save your changes, touch “OK”.
The following information fields are available:
“PreTare”: This information field shows the value that was input for the tare preset using the
function key with the same name.
“ID1”, “ID2” and “ID3”: These information fields show the identifications that were input using the function
keys with the same name. Note: Instead of “ID1”, “ID2”, and “ID3”, the specified
designations are displayed (Section 6.2.10).
“Target”: This information field displays the target weight that was input using the function key
with the same name.
Chapter 6: The “Weighing” application
42
“–Tol” and “+Tol”: These information fields show the tolerances on the target weight that were input using
the function keys with the same name (Section 6.3.3).
“n”, “x”, “s”, “s.rel”, “Sum”, “<T–”,
“>T+”, “Min”, “Max” and “Diff” These information fields show the following statistical values:
“n”: Cumulative number of weighings
“x”: Mean weight of all saved weighings
“s”: Absolute standard deviation
“s.rel”: Relative standard deviation (in %)
“Sum”: Cumulative weight of all saved weighings.
“<T–” Number of weight values below the lower tolerance limit
“>T+” Number of weight values above the upper tolerance limit
“Min” Lowest weight value of the current series of measurements
“Max” Highest weight value of the current series of measurements
“Diff” Difference between the lowest and highest weight values
You will find information about how to use the statistics in Section 6.3.5.
“Info Unit”: This information field shows the weighing result in the second unit you chose (Section
6.2.6).
Factory setting: No information fields activated.
6.2.5 Manual/automatic transfer of weight values
In this menu item you specify whether the balance should operate with automatic weight transfer.
“Manual”: When this setting is used, and series weighings are carried out, the ”M+” function key
must be touched after each weighing to accept the weight value into the statistics. This
setting is recommended for dispensing to a target value, because with automatic
weight acceptance, there is a danger that the balance accepts the weight before the
dispensing process is complete.
“Automatic”: Each time a weighing is carried out, the balance detects the change in weight and
automatically writes the weight value into the statistics without a key having to be
touched.
Factory setting: “Manual”.
Chapter 6: The “Weighing” application
43
6.2.6 Selecting weighing units
In the “Display Unit” and “Info Unit” menus, you specify which weighing units you wish to work with. By choosing different units,
you can have the weighing result displayed in two different weighing units simultaneously.
The same selection of units is available for both the “Display Unit” and the “Info Unit”.
When the “Display Unit” is changed, the current weighing result, the saved weighing
results (sum), and the statistical values are displayed in the new unit. On the other hand,
the values for tare preset, target weight, and tolerances are still displayed in the unit
which was selected at the time these values were defined.
The “Info Unit” is used for the information field with the same name (Section 6.2.4).
Factory setting: AX balances MX/UMX balances
“Display Unit”: “g” (gram) “mg” (milligram)
“Info Unit”: “mg” (milligram) “µg” (microgram)
6.2.7 Defining custom weighing units
You can use the two menus “Custom Unit” and “Free Unit” to define your own weighing units.
You can use a custom weighing unit to perform calculations based directly on the
weighing result as soon as it is obtained (e.g. for surface areas or volumes). The custom
weighing units are available in all menus and input fields in which you select weighing
units.
Note: This function is not available on certified balances.
The menus for defining the two custom weighing units are identical. The following fields
are available:
“Formula”: Here you define how the value for the “Factor” (which you specify afterwards) should
be calculated. Two calculation formulae are available, in which “F” represents the
factor and “Net” the net weight value. The first formula multiplies the net weight by the
factor, whereas the second formula divides the factor by the net weight. The formula
can be used, for example, to take immediate account of a known error factor in the
weight determination.
“Factor (F)”: Here you specify the factor to be applied to the weighing result (net weight), using
the formula previously selected.
“Name”: Enter a name for your custom weighing unit (max. 4 characters).
“Result display”: Here you define the display increments for the weighing result. The weighing result
is rounded by the display increment (e.g. with a display increment of 0.05, a
measured result of 123.4777 is displayed as 123.50). Note: This function can only
be used to reduce the resolution of the weighing result, so do not enter a value that
exceeds the maximum resolution of your balance!
Factory setting: No custom weighing units defined.

6.3.1).
“Single value”: Here you specify whether individual
values are to be printed on the record,
or only the final result (e.g. with series
weighings).
Options for recording the final result
In this submenu you specify the information to be printed on the record for the final result.
These settings are intended mainly for series weighings in which the statistics are used
(Section 6.3.5).
Factory setting: All information items for the end result are activated.
On the first page of the menu, the following information items for the record of the end
result are available:

6.2.10 Defining identifications and record titles
In the “Identification” menu you specify titles for the weighing records and designations for the identifications.
An identical alphanumeric input field is available for all types of input (shown illustrated at right).
“Title 1” and “Title 2” : The designations entered appear in the title of the weighing records. The maximum
length of the record title is 20 characters.
“ID1 Label”, “ID2 Label”, “ID3 Label”: The designations entered (max. 20 characters) appear below the corresponding ID
function keys and as designation of the respective information fields (Section 6.3.6).
The ID designations are also printed on the weighing record.
In practice, “ID1 Label” can, for example, be called “Client”, “ID2 Label” “Job”, and
“ID3 Label” “Lot”.
Factory setting: No record titles specified

6.2.11 Parameters for processing bar code data
If there is a bar code reader connected to your balance, you can specify in the “Bar code input” menu how this data should be
processed.
The following settings can be selected:
“ID1”, “ID2”, and “ID3”: The captured data is treated as identification text and assigned to the corresponding
identification (Section 6.3.6). Note: Instead of “ID1”, “ID2”, and “ID3”, the specified
designations are displayed (Section 6.2.10).
“PreTare”: The bar code data is interpreted as the value for the tare preset (Section 6.3.1).
“To Host”: The bar code data is not processed in the balance, but transmitted directly to a
connected PC. If no PC is connected, or if it cannot accept this data, the data is
ignored.
“Off”: No bar code data is processed. This is the setting to use when no bar code reader
is connected.
Factory setting: “ID1”.
Note: When you connect a bar code reader to your balance, you must configure the interface in the system settings to match (Section
5.8).
6.3 Working with the “Weighing” application
You have already learned how to do a simple weighing in Chapter 3. In this chapter we will show you how to use the various functions
of the “Weighing” application in practice.
6.3.1 Manually entering the tare preset
You normally determine the tare by placing the weighing container on the balance and then touching the «1» key. However,
if you are going to work with the same weighing container for a long period of time, you can enter its weight manually instead. This
saves you having to tare when you place the weighing container on the balance. When the weighing container is taken off the balance,
the tare weight is shown as a negative value; when it is replaced, the display shows zero and the balance is immediately ready for
weighing again.
For you to be able to enter a tare preset value, the corresponding function key must be
activated (Section 6.2.2). After the function key is touched, the window for entering the
tare value opens.
Chapter 6: The “Weighing” application
49
Key the desired tare value in. Check the weighing unit: this is displayed to the right of
the tare value. If you touch the weighing unit, the units available for selection are
displayed. Note: The units are not converted automatically, i.e. if you input a value in
a particular unit, this value remains, even if you change the weighing unit.
After you have entered the value, touch “OK” to activate the tare preset.
If you have activated the corresponding information field (Section 6.2.4), the value
which has been input for the tare preset will be displayed below the weighing result.
6.3.2 Changing the resolution of the weighing result
Before it leaves the factory, the balance is set so that the weighing result is displayed with the maximum resolution depending on
the model (corresponding to 1d). You can change the resolution of the weighing result at any time during your work.
For you to be able to change the resolution of the weighing result, the corresponding
function keys must be activated (Section 6.2.2). You can use these function keys to
display the weighing result at a lower resolution:
“1/10d”: 10x lower resolution
“1/100d”: 100x lower resolution
“1/1000d”: 1000x lower resolution
6.3.3 Specifying the target weight and tolerances
Your balance provides you with several special functions to make weighing-in to a specified target value easier. For you to be able
to enter a target weight and the associated tolerances, the corresponding function keys must be activated (Section 6.2.2).
You can use this function key to specify the desired target weight. This makes weighingin to a target value easier for you, because the target value is also used by the
“SmartTrac” graphical weighing-in aid (Section 6.3.4).
When the function key is touched, the window for entering the target weight appears.
Key in the desired target value. Check the weighing unit which is displayed to the right
of the target value. If you touch the weighing unit, the units available for selection are
displayed. Note: The units are not converted automatically, i.e. if you input a value in
a particular unit, this value remains, even if you change the weighing unit.
After you have entered the value, touch “OK” to activate the tare preset.
If you have activated the corresponding information field (Section 6.2.4), the value
which has been input for the target weight will be displayed below the weighing result.
You can use these two function keys to specify the accuracy with which you wish to
weigh in. The selected tolerances are also used by “SmartTrac” (Section 6.3.4).
Chapter 6: The “Weighing” application
50
When one or other of the function keys for the minus or plus tolerance is
window for entering the corresponding value appears. The input window is the same
as for the target value. Here, too, check the unit which is displayed to the right of the
tolerance value. You can specify the tolerance as a percentage (%) or as an absolute
value in one of the available weighing units.
After you have input the respective value, touch “OK” to activate the tolerance.
If you have activated the corresponding information fields (Section 6.2.4), the specified
tolerance values are displayed below the weighing result.

, the
6.3.4 The “SmartTrac” graphical weighing-in aid
“SmartTrac” is a graphical weighing-in aid which makes weighing-in to a specific target value easier for you. In the application,
“SmartTrac” appears below the weighing result on the right-hand side of the display.
You can choose between various different display modes for “SmartTrac”, or turn it off.
Also, instead of “SmartTrac”, you can display a stopwatch.
To make the “SmartTrac” selection, a menu is available which you can call up either
with the «7» key or by directly touching the “SmartTrac” zone in the display.
Important: The marks for the target value and the upper and lower tolerance limits are
only shown if corresponding values for the target weight and tolerances have been
specified as described in the preceding section.
The various different “SmartTrac” display modes are described below.
SmartTrac 1
The vertical segments in the left-hand semicircle indicate that the present weight is below
the target value; if segments appear in the right-hand semicircle, the weight is above
the target value. The two lower quadrants symbolize the coarse range, and the two upper
quadrants the fine range. You can weigh-in rapidly until the segments in the lower
quadrant disappear, and then fine-dispense until the only segments visible lie between
the tolerance marks. If no more segments are visible, the target weight has been exactly
reached.
SmartTrac 2
The target weight is exactly reached when the tips of all 4 triangles touch each other.
The triangles below the horizontal line symbolize the coarse range, those above the line
symbolize the fine range for precisely weighing-in to the target value (represented by
the vertical line).
SmartTrac 3
The lower bar symbolizes the coarse range for fast weighing-in. The upper bar with the
two tolerance marks represents the fine range for precise weighing-in to the target value
(represented by the vertical line).
Chapter 6: The “Weighing” application
51
SmartTrac 4
The target value is represented by the vertical line. During weighing-in, triangular
segments appear to the left and right of this line, which disappear toward the point at
the top as the fine range is approached. When the fine range is reached, a pointer
appears which makes precise fine-dispensing to the target value easy.
SmartTrac 5
The target value is represented by the vertical line located between the two tolerance
marks. In the coarse range, a horizontal pointer appears which moves upward during
weighing-in. The horizontal separating line symbolizes the boundary between the
coarse and fine ranges. When this is reached, a vertical pointer appears which moves
toward the right in the direction of the target weight while fine-dispensing continues.
SmartTrac 6
During weighing-in, first the glass flask respresenting the coarse range fills. As soon as
the fine range is reached, the increasing weight is shown in the vertical bar which also
has marks for the target value and the tolerance limits.
Stopwatch
The stopwatch is mentioned here for the sake of completeness, because it can be
activated in the same menu as “SmartTrac”. The stopwatch supports you when
performing time-critical tasks. To start the stopwatch, touch the key with the arrow
symbol. Touching the key again stops the stopwatch. The “0:00” key is used to reset
the stopwatch to zero.
6.3.5 Weighing-in and using the statistics
When you have specified the target weight and tolerances, and activated the appropriate “SmartTrac”, you can start weighing-in. If
you want to compare the weights of a series of identical weighing samples, you can use the statistics functions which are built into
your balance.
For you to be able to use the statistics, the 4 function keys shown at the left must be
activated (Section 6.2.2).
To make optimal use of the statistics functions, a printer should be connected to your
balance. If this is not the case, we recommend activating the information fields for the
statistics (Section 6.2.4). Even without a printer, the information fields give you a
summary of the statistical values. However, if a printer is connected to your balance,
you can leave the target weight and tolerances displayed, because all the statistical
values are on the record printed on the printer.
If you work with a weighing container, place this on the weighing pan and touch the
«1» key to set the display to zero. (If you have specified a tare preset, touching
this key is not necessary).
Chapter 6: The “Weighing” application
52
Place the first sample on the weighing pan and wait until the stability detector is
extinguished. Touch the “M+” function key to accept the weight into the statistics. The
weight value measured is then printed out.
Note: If you have activated automatic weight transfer (Section 6.2.5) the weight is
accepted automatically as soon as the value becomes stable. If you have activated the
automatic door function (Section 5.7), the glass draft shield closes automatically for
the weight to be transferred and then opens again for you to place the next sample on
the pan.
Remove the first sample and then place the further samples on the pan in sequence.
Confirm each weight value with the “M+” function key.
Note: If you have placed a wrong weight on the pan by mistake and accepted the
weighing result, you can delete the last value with the “CL Last” function key. (This key
is only available if the memory already has values stored in it; otherwise, the key is
shown gray and cannot be operated.)
After you have weighed all the samples in, touch the “Result” function key. (This key
is only available if the memory already has values stored in it; otherwise, the key is
shown gray and cannot be operated.) This temporarily suspends the measurement
process, but you can continue the series at any time. When you want to finally terminate
the measurement process and clear the memory for a new series, touch the “CL Sum”
function key.
After you have touched the “Result” function key, the results of the weighing series
appear in the display. You can use the arrow keys to page backward and forward
between the different screen pages.

You can produce the record for the weighing results by touching the “Print” key.
The illustration on the left shows an example of a record. Which values are shown on
the record depends on the settings for the weighing record (Section 6.2.8). The
individual items of information on the weighing record have the following meanings:
“Nominal”: Specified target weight
“–Tol”: Specified lower tolerance
“+Tol”: Specified upper tolerance
“1”...“5”: Number and weight of each sample
“n”: Number of samples
“<T–”: Number of samples whose weight is below the lower tolerance limit

“Sum”: Sum of all individual weights
........................
6.3.6 Working with identifications
Identifications are descriptive texts of individual weighing procedures which allow unambiguous cross-referencing of weighing
samples to specific jobs or clients. The identifications are also printed on the weighing records, or transmitted to a computer if one
is connected.
For you to be able to work with the identifications, the ID function keys must be activated
(Chapter 6.2.2).
At the factory, the ID function keys are given the designations “ID1”, “ID2”, and “ID3”.
You can replace these designations by more meaningful titles corresponding to your
application (Section 6.2.10). The chosen designations (e.g. “Client” for ID1, “Job” for
ID2 and “Lot” for ID3) appear below the corresponding ID function key.
When you work with identifications we recommend you to activate the corresponding
information fields (Section 6.2.4). The information fields have the same designations
as the respective ID function keys.
Chapter 6: The “Weighing” application
54
The example on the left shows the balance display after the ID function keys, and the
ID information fields, have been activated.
The practical example described below is based on the designations shown in the
illustration above.
In the application, when you process a job for a client, and when weighing is complete,
touch the “ID1” (“Client”) function key and a field appears to input the client (see
illustration at left). Enter the name, and confirm your input with “OK”.
If you then touch the “ID2” (“Job”) key, a similar field appears for you to enter the job
designation, and when you touch the “ID3” (“Lot”) key, you can enter the lot
designation. Each designation can be up to 24 characters long.

When you have completed all the inputs, you can again check the identifications you
have selected by means of the information fields in the display.
All the identifications remain stored until they are replaced by new designations.
If you have defined the weighing record so that the identifications should also be printed
out (Section 6.2.8), the specified ID designations (e.g.“Client”) and the text you entered
(e.g. “Mettler-Toledo GmbH”) are both printed out. If you forget to enter the identification
after a weighing operation, before the record is printed out you will be prompted to input
the identification. The illustration on the left shows a weighing record with the
identifications corresponding to the above example.

6.4 Adjusting the balance and checking the adjustment
At the factory your balance was set for fully automatic adjustment using ProFACT. ProFACT adjusts and linearizes the balance
automatically as soon as a change in environmental conditions makes it necessary. However, you can also carry out a manual
adjustment and/or check using the internal weight, or an external weight, at any time.
In the descriptions following below, it is assumed that the respective function keys for adjustment and testing (Section 6.2.2) are
activated.
6.4.1 Fully automatic adjustment using ProFACT
ProFACT adjusts and linearizes your balance fully automatically based on pre-specified criteria (Section 5.3.3).
As soon as the pre-specified criterion is fulfilled (time and/or temperature criterion),
adjustment begins. While adjustment is taking place, a window is opened which
provides you with information about the adjustment process. If you are working with the
balance just at that moment, you can terminate ProFACT with the “Cancel” key. The
balance will start the adjustment again at the next opportunity. After completing the
adjustment, the balance automatically returns to the application. Each ProFACT
adjustment is automatically recorded according to your settings (Section 5.3.3). What
information in addition to the adjustment data is recorded, depends on your settings for
the adjustment and test record (Section 5.3.2). You will find an example of a record in
Section 6.4.6.
6.4.2 Adjustment using the internal weight
By touching this function key, you start adjustment (calibration) of the balance using
the built-in calibration weight.
You can hear the motor placing the internal weight on the weighing pan and then
removing it again. While adjustment is taking place, the window shown on the left is
opened. You can terminate the adjustment process at any time by touching the “Cancel”
key.
When the adjustment is complete, one or other of the following messages appears:
"Adjustment successfully completed". Touch “OK” to return to the application.
If a printer is connected to the balance, the adjustment is automatically recorded
according to the system settings you selected for adjustment and test (Section 5.3). You
will find an example of a record in Section 6.4.6.
Chapter 6: The “Weighing” application
56
"An error has occurred while adjusting and the adjustment has been terminated."
This message also appears if you terminate the adjustment yourself. You can repeat the
adjustment process or return to the application by touching “OK”.
6.4.3 Adjustment using an external weight
By touching this function key, you start adjustment (calibration) of the balance using
an external calibration weight. Note: Depending on country-specific regulations, this
function may not be available on certified balances.
You are prompted to load the adjustment weight onto the pan. The weight needed for
adjustment is shown at the bottom edge of the window. If the automatic door function
is active (Section 5.7), the glass draft shield opens automatically for you to place the
weight on the pan.
Important: Make sure that you place the correct adjustment weight on the weighing pan;
otherwise, the adjustment process will be terminated with an error message. The
adjustment weight can be specified in the system settings (Section 5.3).
If the automatic door function is active, the glass draft shield closes automatically after
you have placed the weight on the pan; otherwise, you must close it manually by
touching the «2» key. While adjustment is taking place, the window shown on the left
is opened. You can terminate the adjustment process at any time by touching the
“Cancel” key.
When the adjustment process is complete, you will be prompted to unload the weight.
Remove the weight from the weighing pan.
The balance confirms successful completion of the adjustment. Touch “OK” to return to
the application.
If a printer is connected to the balance, a record of the adjustment is automatically
printed according to the system settings you made for adjustment and test (Section
5.3). An example of an adjustment record is shown in Section 6.4.6.
If an error occurs during adjustment, a corresponding message appears similar to the
one for adjustment with the internal weight (see previous section).
6.4.4 Checking the adjustment with the internal weight
By touching this function key, you can use the internal weight to check the correct
adjustment (calibration) of your balance.
The checking procedure is similar to the procedure for adjustment using the internal
weight (Section 6.4.2).
Chapter 6: The “Weighing” application
57
The successful conclusion of the checking procedure is confirmed with the window
shown on the left. If a printer is connected to the balance, a record of the check is
automatically printed out according to the system settings you selected for adjustment
and test (Section 5.3). You will find an example of a record in Section 6.4.6.
If an error occurs during adjustment, a corresponding message appears.
6.4.5 Checking the adjustment with an external weight
By touching this function key, you can use an external weight to check the correct
adjustment (calibration) of your balance.
The checking procedure is similar to the procedure for adjustment using an external
weight (Section 6.4.3). When the check is complete, a message appears which is
similar to the one displayed after checking the adjustment with the internal weight. If a
printer is connected to the balance, a record of the check is automatically printed out
according to the system settings you selected for adjustment and test (Section 5.3). You
will find an example of a record in Section 6.4.6.

7 The "Percent Weighing" Application
In this chapter we will introduce you to the "Percent Weighing" application. You will find information for practical work with this
application and about the application-specific settings that are available (you will find information about non-application-specific
system settings in Chapter 5).
7.1 Introducing the "Percent Weighing" application
The "Percent Weighing" application allows you to weigh in to a specified value (100 %) and to detect deviations from this target
value. "SmartTrac" allows you to determine rapidly where the sample weight lies in relation to the tolerances.
Many of the application-specific settings are identical to the those in the "Weighing" application. However, for percent weighing you
have additional application-specific function keys and information fields available. In the descriptions that follow, only those settings
are described in detail which differ from the "Weighing" application.
7.2 Selecting the application
If the "Percent Weighing" application is not already active, touch the «6» key. In the
selection window, touch the symbol for the application.
6
Note: If you do not wish to work with the currently active user profile, first select the
desired profile with the «4» key.

7.4 Working with the “Percent Weighing” application
In this section you will learn how to work with the “Percent Weighing” application. You already know, of course, how to determine
tare, target, and tolerance values, and how to use statistical functions and identifications. You have already learnt about these
possibilities in the “Weighing” application (Section 6.3) so they will not be repeated here.
Place the reference weight on the weighing pan.
If the reference weight is to represent 100%, touch the function key “Set100%”.
As soon as the weighing result is stable, the measured weight is accepted as reference.
Displayed in the information fields are the reference value (100%) and the absolute
weight of the reference.
If you wish to assign a variable reference to the weight on the pan, touch the “VarRef%”
key instead. An input field appears in which you can enter the percentage value (e.g.
55%) to which the weight on the pan should correspond.
Reference% 100.0 %
Reference 19.0400 g
308.482 %
Place the weighing sample on the pan. The results display shows the weight of the
weighing sample as a percentage of the reference weight.
You can use the «8» key to print the weighing result. The illustration at left shows part
of an example of a report in which the reference as a percentage and the reference weight
are shown (depending on your individual settings your report may differ from this
example).

8 The “Density” Application
In this chapter we will introduce you to the “Density” application. You w ill find information for practical work with this application
and about the application-specific settings that are available (you will find information about non-application-specific settings in
Chapter 5).
8.1 Introducing the “Density” application
The “Density” application allows you to determine the density of solids and liquids, as well as of pasty and porous substances. Each
sample can be given an identification, and the integral statistics functions allow statistical evaluation of measurement series.
Determination of density is performed using Archimedes' principle which states that any body which is immersed in a liquid undergoes
a loss in weight equal to the weight of the liquid it displaces.
To carry out density determinations, you can use the below-the-balance hanger of your balance (Section 2.8). However, for
determining the density of solids we recommend you to work with the optional density kit which contains all the necessary accessories
and aids for convenient and precise density determination (you will find ordering information in Chapter 12). Separate instructions
are supplied with the density kit which explain how to install and use it.
For determining the density of liquids you also need a sinker, which you can also obtain from your METTLER TOLEDO dealer.
Alternatively, the “Density” application also supports density determination of liquids with a pycnometer. Pycnometers can be
obtained from specialist companies for laboratory equipment. For density determination of pasty substances a gamma sphere is
required. Your dealer will be pleased to tell you where you can obtain one. Please follow the instructions delivered with these
accessories: they contain useful information about working with them, handling them, and caring for them.
8.2 Selecting the application
If the “Density” application is not already active, touch the «6» key. In the selection
window, touch the symbol for the application.
6
Note: If you do not wish to work with the current user profile, first use the «4» key to select
the desired profile.
When the application is selected for the first time, the display shown at left appears.
Before leaving the factory, special function keys and information fields for density
determination have been activated. The balance is set for performing density determination of solids using water as auxiliary liquid. You can change these settings to meet
your needs as described in the sections following below.
Chapter 8: The "Density" Application
64
8.3 Settings for the “Density” application
A number of application-specific settings are available for density determination which you can use to adapt the application to your
needs. Note: Your settings apply for the currently active user profile. Make sure that the desired profile has been selected before you
make the settings.
8.3.1 Overview
The application-dependent settings can be accessed with the «7» key. When this key is touched, the first of 3 menu pages with the
application-dependent settings for density determination appears.
The following settings are available for the “Density” application:
Some of the settings are identical to those for the “Weighing” application (Section 6.2). Only the settings that are different are described
below. These are in the following menus:
“Method”: You use this menu to select the type of density determination.
“Aux. liquid”: You use this menu to specify the auxiliary liquid you will work with.
“Function keys”: Additional special function keys are available for density determination.
“Info field”: Additional information fields are available for density determination.
“Protocol”: Additional items of information are available for the reports of density determination.

Chapter 8: The “Density” Application
65
8.3.3 Selecting the auxiliary liquid
In this menu you can specify the auxiliary liquid you wish to work with. This setting is only relevant if you are determining the
density of solids! You can choose from the following auxiliary liquids:
“Water”: Distilled water is used as the auxiliary liquid. The density of
distilled water at various different temperatures is stored in the
balance (density table from 10°C to 30 °C) so it need not be
known.
“Ethanol”: Ethanol is used as the auxiliary liquid. The density of ethanol at
various different temperatures (from 10 °C to 30 °C) is also stored
in the balance so it need not be known.
“Other”: An auxiliary liquid of the user's choice, whose density at the
current temperature must be known.
Factory setting: “Water” is activated as auxiliary liquid.
8.3.4 Special function keys for density determination
Additional settings for density determination are available in the function key menu.
On the first page of the menu there are the following function keys for density
determination:
“Start”: You use this function key to start the density determination, so this
key must always be activated!
“Density AL”: You use this function key to enter the density of the auxiliary
liquid. This key is only needed if an auxiliary liquid other than
water or ethanol is being used.
“Temp. (AL)”: You use this function key to enter the temperature of the auxiliary
liquid. You only need to use this key if you are using distilled water
or ethanol, because for other liquids the density at the current
temperature always has to be entered. For methods which do not
use an auxiliary liquid the key can be used to input the ambient
temperature so that it appears on the determination reports.
“Vol. Sinker”: You can use this function key to enter the volume of the sinker.
You only need to activate this key if you wish to determine the
density of a liquid using a sinker.
“Vol. Pycno”: You can use this function key to enter the volume of the
pycnometer. You only need to activate this key if you wish to
determine the density of liquids using a pycnometer.
“Wgt. Pycno”: You can use this key to enter the weight of the pycnometer. You
only need to activate this key if you wish to determine the density
of liquids using a pycnometer.
“Result”: You can use this function key to display the results of the density
determinations (statistics). Note: If there are no results in the
statistics, the key is shown gray and cannot be operated.
Chapter 8: The "Density" Application
66
On the last page of the menu there are the following function keys for density
determination:
“Sample ID”: You can use this function key to assign an identification to each
sample whose density you determine, so you can identify it
unambiguously when the results are displayed.
“Sample No.”: You can use this function key to assign a number to each sample
whose density you determine. This makes it easier to identify the
individual samples of a sequence.
“CL Sum”: You can use this function key to delete the results of a series of
density determinations you have stored (statistics) so you can
start a new series of measurements.
All other function keys are the same as for the “Weighing” application.

Chapter 8: The "Density" Application
68
8.3.8 Specifying the number of decimal places for the result
In the ”Density decimal points” you can specify the number of decimal places for displaying the result of the density determination.
You can choose between the following settings:
“1” ... “5”: The result of the density determination is shown in the correspon-
ding information field and on the reports with the number of
decimal places selected.
Factory setting: “3”.
8.4 Working with the “Density” Application
In this section you will learn how to work with the “Density” application and the various methods of determining density. It is assumed
that the “Density” application has already been selected.
8.4.1 Determining the density of non-porous solids
When determining the density of non-porous solids the solid is first weighed in air and then in the auxiliary liquid. The difference in
weight gives the buoyancy force which is used by the software to calculate the density.
In the application-specific settings select “Solid” as the method (Section 8.3.2) and
specify the desired auxiliary liquid (Section 8.3.3).
Activate the appropriate function keys and information fields (Sections 8.3.4 and 8.3.5).
Note: The example illustrated at left shows settings for determining the density of solids
using distilled water as auxiliary liquid. If you use a liquid other than water or ethanol,
activate function key “Density AL” instead of “Temp. (AL)”.
If you use water or ethanol as auxiliary liquid, enter the temperature using the function
key “Temp. (AL)” (density tables for these two liquids are stored in the balance). The
illustration at left shows the input field to be used.
Chapter 8: The “Density” Application
69
If you use an auxiliary liquid other than water or ethanol, activate the function key
“Density AL” and use this key to enter the density of the auxiliary liquid being used at
the current temperature. This is necessary because there are no density tables in the
balance for liquids other than water and ethanol. The value entered appears in the
information field with the same name, which you should also activate. Note: In the
example at left, the activated function key “Temp. (AL)” is not required for density
determination using an auxiliary liquid other than water or ethanol. However, you can
use this key to enter the current ambient temperature, which can then be printed out on
reports and shows the temperature at which the density result was determined.
Touch the «1» key on the terminal to tare the balance.
Touch the “Start” function key to start the density determination. After a short pause you
will be prompted to place the solid on the weighing pan (weighing in air).
If you are working with the below-the-balance hanger, hang the solid on the hanger. If
you are working with the optional density kit, follow the instructions supplied with the
kit.
The weight of the solid on the weighing pan appears in the lower left corner of the
window.
Touch the “OK” key to accept the weight value.
After a short pause you will be prompted to place the solid in the auxiliary liquid.
If you are working with the below-the-balance hanger, place the container with the
auxiliary liquid below the hanger. If you are working the optional density kit, follow the
instructions supplied with the kit. In either case, ensure that the solid is immersed at least
1 cm in the liquid and that there are no air bubbles in the container.
The weight of the solid in the liquid appears in the lower left corner of the window.
Touch the “OK” key to accept the weight value.
The balance now determines the density of the solid, and you will then be asked whether
you wish to accept the result of the density determination into the statistics.
Touch the “OK” key to accept the density value into the statistics. If you do not wish to
accept the result into the statistics, touch “Cancel” instead. The result is then held until
the next measurement and is shown in the “Density” information field, but it is not
accepted into the statistics.
You will find information about using the density statistics in Section 8.5.3.
You can use the «8» key to print out the result of the current density determination.
You will find an example of a report and corresponding explanations in Section 8.5.2.
Chapter 8: The "Density" Application
70
8.4.2 Determining the density of liquids using a sinker
To determine the density of liquids, use is often made of a sinker whose volume is known. The sinker is first weighed in air, and then
in the liquid whose density is to be determined. The difference in weight gives the buoyancy force which is used by the software to
calculate the density.
In the application-specific settings, for the method select “Liquid” (Section 8.3.2).
Activate suitable function keys and information fields (Sections 8.3.4 and 8.3.5). The
example at left shows appropriate settings for determining the density using a sinker.
Note: The function “Temp. (AL)” and the information field with the same name activated
in the example at left are not required for this method. However, you can use these to
input the current ambient temperature, which can then be printed out on the report and
shows the temperature at which the density result was obtained.
Touch the “Vol. Sinker” function key and enter the volume of the sinker (in this example
10.00000 cm3).
Touch the «1» key on the terminal to tare the balance.
Touch the “Start” function key to start the density determination. After a short pause, you
will be prompted to mount the sinker (for weighing in air).

8.4.4 Determining the density of liquids using a pycnometer
The density of liquids is often determined using a pycnometer, which is a glass container whose own capacity and weight are known.
The liquid is poured into the pycnometer and weighed.
In the application-specific settings select the method “pycnometer” (Section 8.3.2).
Activate suitable function keys and information fields (Sections 8.3.4 and 8.3.5). The
example at left shows suitable settings for determining the density of liquids using a
pycnometer. Note: The function key “Temp. (AL)” and the information field with the

8.4.5 Determining the density of porous solids
To determine the density of porous solids the solid is first weighed in air. In contrast to non-porous solids this requires additional
use of an oil bath which seals the pores of the solid with oil before it is weighed in the auxiliary liquid.
In the application-specific settings select the method “Solid porous” (Section 8.3.2)
and specify the desired auxiliary liquid (Section 8.3.3).
Activate suitable function keys and information fields (Sections 8.3.4 and 8.3.5).
Note: The example at left shows settings for determining the density of porous solids
using distilled water as auxiliary liquid. If you use an auxiliary liquid other than water
or ethanol, you should activate the function key “Density AL” instead of “Temp. (AL)”.
If you use water or ethanol as auxiliary liquid, use the “Temp. (AL)” key to enter their
temperature (density tables for these two liquids are stored in the balance). The
illustration at left shows the corresponding input field.
If you are using an auxiliary liquid other than water or ethanol, activate the “Density AL”
function key and use it to enter the density of the auxiliary liquid you are using at the
current temperature. This is necessary because for liquids other than water and ethanol
there are no density tables in the balance. The value input appears in the information
field with the same name, which you should also activate. Note: The function key
“Temp. (AL)” which is activated in the example shown at left is not required for density
determination using an auxiliary liquid other than water or ethanol. You can, however,
use it to enter the current ambient temperature which will be printed out on the reports
and shows the temperature at which the density result was obtained.
Touch the «1» key on the terminal to tare the balance.
Touch the “Start” key to start the density determination. After a short pause you will be
prompted to place the solid on the weighing pan for the first weighing in air.
If you are working with the below-the balance hanger, hang the solid on the hanger. If
you are working with the optional density kit, follow the instructions delivered with the
kit.
The weight of the solid on the weighing pan (or hanger) appears in the lower left corner
of the window.
Touch the “OK” key to accept the weight.
After a short pause you will be prompted to immerse the solid in the oil bath and then
to replace it on the weighing pan (or hanger) for the second weighing in air.
Place the oil-soaked solid in the same place again (weighing pan or hanger) as for the
first weighing in air.
The weight of the oil-soaked solid is displayed in the lower left corner of the window.
Touch the “OK” key to accept the weight value.
Chapter 8: The "Density" Application
74
After a short pause you will be prompted to immerse the oil-soaked solid in the auxiliary
liquid. If you are working with the below-the-balance hanger, place the container with
the auxiliary liquid beneath the hanger. If you are working with the optional density kit,
follow the instructions delivered with the kit. In either case, ensure that the solid is
immersed at least 1 cm in the liquid and that there are no air bubbles in the container.
The weight of the oil-soaked solid in the liquid is displayed in the lower left corner of the
window.
Touch the “OK” key to accept the weight value.
The balance now determines the density of the solid and you will then be asked whether
you wish to accept the result ot the density determination into the statistics.
Touch the “OK” key to accept the density value into the statistics. If you do not wish to
accept the result into the statistics, touch “Cancel” instead. The result is held until the
next measurement and displayed in the “Density” information field but not accepted into
the statistics.
You will find information about using the density statistics in Section 8.5.3.
You can use the «8» key to print out the result of the current density determination.
You will find an example with explanations in Section 8.5.2.
8.5 Additional functions of the “Density” application
You can assign an identification and a number to each sample. This makes it easier to identify the results of the individual samples.
You can use the statistics to evaluate complete series of measurements. These functions are described in the sections that follow
below.
8.5.1 Sample identification
If you have activated the two function keys “Sample ID” and “Sample No.” (Section
8.3.4) you can assign an identification text and a number to each sample.
For each of the two functions there is an identical alphanumeric input field.
The identifications you enter (texts and numbers) appear on the reports and in the
statistics, which ensures that the individual measurement values can be identified
unambiguously.
You can also activate the two information fields “Sample ID” and “Sample No.” (section
8.3.5) so that the texts and numbers you have entered are also shown in the display.
The illustration at left shows an example with the function keys and information fields
for activated sample identification.

8.5.3 Using the density statistics
Statistics are maintained for the density determinations. They store the last 10 results of density determinations you made and
accepted into the statistics. Note: The statistics do not differentiate between the methods used for the density determinations, but
simply store the last 10 results made and accepted.
To use the density statistics, the two function keys “Result” and “CL Sum” must be
activated (Section 8.3.4).
You can call up the statistics with the “Result” function key.
Note: If the statistics do not contain any values, the key is shown gray and cannot be
operated.
The statistics displayed are the values you have activated in the “Result” submenu of
the report settings (Section 8.3.6). The individual items of information in the density
statistics have the following meanings:
“n”: Number of samples
“x”: Mean density of all samples
“s”: Absolute standard deviation
“s.rel”: Relative standard deviation in %
“Min”: Lowest density determined
“Max”: Highest density determined
“Diff”: Difference between highest and lowest densities
The statistics can be printed out if required.
If you wish to close a measuring series, touch the “CL Sum” function keyy to clear
(delete) the statistics.

9 The “Minimum Weighing” Application
In this chapter we will introduce you to the “Minimum Weighing” application. You will find information for practical work with this
application and about the application-specific settings that are available (you will find information about non-application-specific
settings in Chapter 5).
9.1 Introducing the “Minimum Weighing” Application
The “Minimum Weighing” application must be put into operation and programmed by a service technician. If you need this
application, but it is not available in the applications menu, please contact your METTLER TOLEDO dealer.
The “Minimum Weighing” application ensures that the weighing results lie within defined tolerances specified by your quality
assurance system.
In your own laboratory the service technician will use weights to determine the necessary minimum weighings based on the
requirements of your QS, and will then load these values into the balance. Up to 3 tare values can be defined with the corresponding
minimum weighings. The service technician also sets the weighing parameters to the values needed to comply with the tolerances.
These system settings cannot be changed by the user. The minimum weighing settings apply to all user profiles!
When he has finished programming the balance, the service technician issues a certificate in which the measurements, as well as
the tolerances and the corresponding tare and minimum weights, are recorded. If you work with the “Minimum Weighing” application
you can be sure that the weighing results comply with the specifications of the certificate and therefore with your QS guidelines.
9.2 Selecting the application
If the “Minimum Weighing” application is not already active, touch the «6» key. In the
selection window touch the symbol for the application.
6
Note: If you do not wish to work with the current user profile, first use the «4» key to select
the desired profile.
When you have selected the application, the display shown at left appears. The special
minimum weighing function key and information field have been activated at the factory.
You can change these settings to suit your needs according to the description in the
sections that follow below. The value shown for minimum weighing (0.5 g
in the example shown at left) is calculated from the respective tare weight and the
programmed values and cannot be changed.
Chapter 9: The “Minimum Weighing” Application
78
9.3 Settings for the “Minimum Weighing” application
A number of application-specific settings are available for minimum weighing which you can use to adapt the application to your
needs. Note: Your settings apply for the currently active user profile. Make sure that the desired profile has been selected before you
make the settings.
9.3.1 Overview
The application-dependent settings can be accessed with the «7» key. When this key is touched, the first of 3 menu pages with the
application-dependent settings for minimum weighing appears.
The following settings are available for the “Minimum Weighing” application:
With only few exceptions, these settings are identical to those for the “Weighing” application (Section 6.2). Only the settings that
are different are descrilbed below. These are in the following menus:
“Function keys”: A special function key is available for minimum weighing.
“Info field”: There are three additional information fields for minimum weighing.
“MinWeigh”: Special information can be called up for minimum weighing.
“Protocol”: Additional information for minimum weighing can be printed on the reports.
Please note that in contrast to the “Weighing” application there are no custom units for minimum weighing.
The specific settings for the “Minimum Weighing” application are described in detail in the sections that follow below.
9.3.2 Special function keys for minimum weighing
On the first page of the function keys menu there is an additional setting for minimum weighing:
“–>0<–”: You can use this function key to reset the display value to zero.
Since the minimum weighing value is significantly affected by the
tare value, a difference has to be made between taring and
zeroing (resetting the display to zero). Use this function key to
reset the display to zero, and for taring use the «1» key on
the terminal.
In the “Minimum Weighing” application the function key for selecting the resolution of
the weighing result (“1/10d”, “1/100d” and “1/1000d”) is not available. All the other
function keys are the same as for the “Weighing” application (Section 6.2.2).
Factory setting: “–>0<–” is activated.
Chapter 9: The “Minimum Weighing” Application
9.3.3 Special information fields for minimum weighing
On the first page of the information fields menu there are three additional settings for minimum weighing:
“MinWeigh”: This information field shows the minimum weighing value requi-
red. The value depends on the reference tare and is programmed
on the balance by the service technician.
“Ref. Tare”: This information field shows the reference tare used as the basis
for the required minimum weighing. This value is also programmed on the balance by the service technician.
“Tare”: This information field shows the current tare value.
All other information fields are the same as for the “Weighing” application (Section
6.2.4).
Factory setting: “MinWeigh” is activated.
9.3.4 Information menu for minimum weighing
79
In the application-specific settings there is an additional menu for minimum weighing:
The “MinWeigh” menu is for information only, you cannot use it to make any settings.
To ensure that the certified values are maintained, the balance must be checked at
regular intervals by the service technician. This menu shows when the next test must
be carried out. When this date is reached, a symbol of a weight with a clock appears
below the time to remind you that the test should be carried out. In the lower section of
the menu a maximum of 3 pairs of values for minimum weighing and tare are displayed.
These values, which are programmed by the service technician, indicate the reference
tare weights for which minimum weighing is required (in the example at left, a tare
weight of 10 g requires a net minimum weighing of 1 g). These values are also
displayed in the corresponding information fields (see Chapter 8). This information can
also be printed out if required.
9.3.5 Special record information for minimum weighing
In the submenu with the options for reporting individual values, there are additional settings for minimum weighing:
“Tare”: The current tare value is printed on the report.
“Display Unit”: The selected display unit is printed on the report.
“Info Unit”: The selected information unit is printed on the report.
All other information items printed on the report are the same as for the “Weighing”
application (Section 6.2.8).
Factory setting: “Tare” and “Display Unit” are activated.
Chapter 9: The “Minimum Weighing” Application
80
9.4 Working with the “Minimum Weighing” Application
In this section you will learn how to work with the “Minimum Weighing” application. When you work with “Minimum Weighing” you
can, of course, also specify target values and tolerances and use statistical functions and identifications. You already know these
possibilities from the “Weighing” application (Section 6.3) so they will not be described again here.
Touch the “–>0<–” function key to set the display to zero.
Place the tare (weighing container) on the weighing pan and touch the «1» key
on the terminal to tare the balance. The balance then determines the tare value, after
which it displays the symbol “Net” (net weight) next to the weighing result.
The corresponding information field then displays the minimum weighing required for
the current tare (3.0 g in the example at left). If you have activated the corresponding
information fields, the tare reference value (which determines the minimum weighing)
and the tare weight which has been determined are displayed. The small symbol below
the time indicates that, at the moment, the minimum weighing has not been reached,
and the current weight value may therefore possibly not lie within the tolerances
specified by the QA system.
T 15.0154 g
*N 2.8817 g
Now place the weighing sample on the weighing pan. As soon as the required minimum
weighing is reached, the small symbol below the time disappears.
Should you wish to weigh further weighing samples, if necessary you can reset the
display to zero with the “–>0<–” function key. The determined tare, and therefore also
the required minimum weighing, are retained.
You can use the «8» key to print the weighing result out. The illustration at left shows
part of an example of a report in which the current tare value and the net weighing-in
are printed. (Depending on your individual settings, your own report may differ from this
example). The star to the left of the net weight indicates that the minimum weighing
according to the above example has not been reached, and the value may possibly not
fulfil the QA requirement.

10 Loading Applications via the Internet
In the interest of our customers METTLER TOLEDO continuously develops new applications. The existing applications are also
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.
10.1 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.
10.2 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)
10.3 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.
Click on the relevant application package in the language required.
Enter the data needed for registration.
Download the software package onto your computer.
Chapter 10: Loading Applications via the Internet
82
10.4 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 Chapter 5.8): 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.
Chapter 10: Loading Applications via the Internet
83
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.
10.5 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 !

11 Further important information
11.1 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.
11.2 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.
Chapter 11: Further important information
11.3 Cleaning and service
Periodically clean the weighing pan, the draft cover, the housing, and the terminal of your balance using the brush supplied with it.
To clean the weighing chamber thoroughly, pull the draft cover and/or draft disk (which on the UMX balance
is made up of several parts) and the weighing pan vertically up and off (on the MX/UMX balances it may be
necessary to turn the weighing pan slightly to remove it). When you replace these parts, make sure they are
in the correct position (see Chapter 2).
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 terminal, or the AC adapter!
– Never open the balance, the terminal, 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 balance.

13.2 SOPs - standard operating procedures
In the documentation of a GLP test, the SOPs are a small, but very important part.
Practical experience confirms that SOPs written in-house are followed much better than SOPs written by an an external, anonymous
source.
You will find below a brief overview of the responsibilities in relation to SOPs, as well as a checklist for creating an SOP.
Responsibilities in relation to SOPs
Head of testing laboratory Instructs SOPs to be created
Approves SOPs with date and signature
Testing supervisor Ensures that SOPs are available
Approves SOPs as deputy to laboratory head
Employees Follow the SOPs and other guidelines
GLP quality assurance Checks whether valid SOPs are available
Checks whether the SOPs are followed
Checks how and when changes are documented
Checklist for creating SOPs
Administrative matters Yes No
1. Use of SOP forms
2. Name of testing laboratory
3. Date of creation of SOP
4. Archive reference for SOPs
5. Page number (1 of n)
