Getting to know your balance
In this Section you will be given basic information about your balance. Please read right through this Section carefully even if you
already have experience with METTLER TOLEDO balances; please pay special attention to the safety warnings!
1.1
Introduction
Thank you for choosing a METTLER TOLEDO balance.
The analytical balances of the XS line combine a large number of weighing and adjustment possibilities with exceptionally convenient
operation. With these balances software updates can be downloaded from the Internet and loaded into the balance.
These operating instructions apply to all analytical balances in the XS 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 XS analytical balances
The XS family of anlytical balances comprises a range of analytical balances which differ from each other in relation to their weighing
range and resolution.
The following features are common to all models of the XS lines:
– Fully automatic adjustment “FACT” (calibration and linearization) using internal weight.
– Built-in applications for normal weighing, statistics, formula weighing, and density determination.
– Integral RS232C interface.
– Touch-sensitive graphics terminal (“TouchScreen”) for easy, convenient operation.
A brief word about standards, guidelines, and methods of quality assurance: The XS analytical balances comply with usual standards
and guidelines. They support standard procedures,specifications, working methods, and reports according to GLP (Good Laboratory
Practice), and allow the creation of SOPs (Standard Operating Procedure). In this respect, 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 XS analytical balances have a CE Declaration of Conformity, and METTLER TOLEDO
is certified as manufacturer according to ISO 9001 and ISO 14001.
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 XS analytical balances.
– Key designations are indicated by double angular parentheses (e.g. «On/Off» or «E»).
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. These make working with your
balance easier, as well as ensuring that you use it correctly and economically.

1.4
Safety first
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.
If the instrument is not used according to the manufacturer's Operating Instructions, protection of the instrument may be
impaired (see also § 5.4.4 of EN 60101:01).
The balance may only be used in enclosed interior rooms. It is not advised 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.
Do not use sharp objects to operate the keyboard of your balance!
Although your balance is very ruggedly constructed, it is nevertheless a precision
instrument. Treat it with appropriate 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.
Disposal must take place in accordance with the applicable customer- and countryspecific regulations.

Note: You can also place the terminal free of the
terminal support anywhere around the balance
where the length of the cable allows.
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.
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.
Setting up the balance
16
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 – 240 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.
Plug the AC adapter into the socket in the back of your balance (see illustration)
and into the power supply.
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.
A
A
2.5
Note: If the display field remains dark, even though the power supply
connection functions, first disconnect the balance from the power
supply. Open the terminal by pressing the two levers (A), then swivel
the upper part of the terminal completely open and check that the
cable (B) is correctly plugged in.
B
Left/right operating of the 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.
The position of the handles determines which door(s) of the draft shield (left, right, or
both) is/are opened.
Try various different combinations by moving the external handles into the upper or
lower position. We recommend you to set up the glass draft shield so that it only opens
on the side where the balance is loaded. Your balance then works faster, because there
are fewer troublesome currents of air than when both doors of the draft shield are opened
together.
Setting up the balance
17
2.6
Adjusting the reading angle and positioning the terminal
2.6.1
Adjusting the reading angle
For a steeper reading angle, pull both levers (A) at the side upward. You can then pull
the upper part of the terminal slowly upward until it engages in the desired position.
Three different setting positions are provided.
If you wish to have a flatter reading angle, pull both levers (A) at the side upward, and
press the lower part of the terminal downward. Release both levers and the upper part
of the terminal then engages in the desired position.
A
2.6.2
A
Remove terminal and place close to the balance
The terminal is connected to the balance by a cable. So you can arrange your workplace optimally, the terminal can be removed
from the balance and placed separately.
You can also place the terminal separately (see illustration).
– Switch the balance off.
– Carefully lift the terminal off the terminal support.
You can leave the terminal support on the balance or remove it.
– Pull the cable carefully out from the balance as far as possible.
– Place the terminal where you want it to be.
The cable can also be led out of the back of the balance. If
working this way would be convenient for you, call your METTLER
TOLEDO dealer who will adapt the balance for you.

Your first weighing
In this Section you will get to know those controls and display elements of your balance that are needed to carry out simple weighing
processes. This Section provides an introduction to operating your balance.
3.1
Switching the balance on and off
On
Off
Switch balance on: Briefly press the "On/Off" key. The balance carries out a short test
as soon as it has been switched on, after which it is ready to weigh.
Before you start weighing, make sure that the balance has been connected to the power
supply for at least 120 minutes (see Section 13.1).
The display shown here appears the first time the balance is switched on.
On
Switch balance off: Press the "On/Off" key and hold it pressed until "OFF" appears on
the display. The display then goes blank, and the balance is switched off.
Off
3.2
Performing a simple weighing
To carry out a simple weighing you only need the keys on the lower part of the terminal. Your balance has separate keys for zero
adjustment ("G") and for taring ("H").
G
H
Zero adjustment: The "G" key sets a new zero, and all weights (including the tare)
are measured with reference to this zero. After adjusting the zero both the tare weight
and the net (gross) weight are equal to 0. Use the zero setting key "G" whenever
you want to begin a new weighing process, and first wish to measure the tare weight
precisely.
Taring: If you are working with a weighing container, place it on the weighing pan. Close
the glass draft shield, then press the "H" key to tare the scales. The taring process
sets the weight that has been placed on the scales since the last zero adjustment as the
new tare weight. The previous tare (if there was one) is overwritten. After taring, "Net"
appears on the display, indicating that all the displayed weights are net values.
Note: If, after the "H" key has been pressed, an instruction to press the "G" key
appears, you have attempted to set a negative tare value. This is not permitted. Adjust
the balance’s zero, and perform the taring again.
Weighing: Open the glass draft shield, insert the items to be weighed, and close the
glass draft shield again. As soon as the stability detector icon (the small circle to the
left of the weight display) goes out, the display is stable and you can read off the
weighing result. The stability detector icon is still visible in this diagram, and therefore
the weighing result is not stable.

Basic principles for using the terminal and the software
This Section explains the operating and display elements of your terminal, and also explains the way the software of your balance
is to be used. Please read this Section carefully, because it is the basis for all the operating steps that are explained in later Sections.
4.1
An overview of the terminal
In this Section we will first introduce you to the controls of the terminal (with the exception of the "On/Off", "G" and "H" keys,
which have already been explained in the previous Section). Detailed information on the display will be provided in the next Section.

24
4.2
The display
The illuminated, graphic display of your terminal is a "Touch Screen". It is not only possible to read data and settings, but also to
make settings and to execute functions by touching the display area.
The factory setting of the balance displays the weighing result at a size so that it can
easily be read. In this display mode neither the information fields nor the graphical
"SmartTrac" filling guide are visible.
The "display" function key allows two further display modes to be selected. The next
display mode appears each time the key is pressed. In the two other display modes,
more information is shown than in the standard mode, but the displayed weight itself
is smaller:
Display with information fields and "SmartTrac". The weighing result displayed is
reduced for reasons of space.
Display without information fields but with "SmartTrac". The size of the weight display
is increased because the information fields are not displayed.
The display is divided into different zones (the illustration shows the display including
information fields and "SmartTrac"):

this area you call up the menu in which you may select the desired application (you
can also reach this menu via the "I" key).
2 The date or the time are shown in the upper right-hand corner. You can change the
date or the time by pressing this zone.
3 The current weighing result appears in this area. If you touch the weighing unit (3b)
a window appears in which you can select the desired weighing unit.
If you press the weighing result (3a) another window displays the weighing result
in a larger size. This can be useful if you want to read the weighing result from some
distance away. This window can be closed again by pressing the "OK" button on the
screen.

you at a glance the weighing range that has already been filled and the range that
is still available.
6 This area is reserved for the function keys that offer you direct access to frequently
needed functions and settings for the currently active application. If more than five
function keys are active, you can switch between them using the arrow keys (not
shown in the diagram).
In the other two display modes (where the weighing result is larger but where less
additional information is displayed) it is also possible to make settings by touching
the zones that are visible at the time.
4.3
The balance software
The software controls all your balance’s functions. It also allows the balance to be adjusted for a specific working environment. Please
take note of the following explanations, as they are the basic principles for using your balance.
The software consists of the following levels:
– Applications
– Application-specific settings
– System settings
Applications
I
Applications are software modules for carrying out specific weighing tasks. Your balance is shipped from the
factory with a variety of standard applications (e.g. for normal weighing, statistics, formula weighing and
density determination). Immediately after being switched on, the balance runs the application for ordinary
weighing. The applications are accessible via the "I" key. You will find instructions on working with the
standard applications in Sections 6 – 9.
Application-specific settings
J
These settings allow you to adapt applications to suit your particular needs. The adjustments that can be made
vary according to which application has been selected. Pressing the "J" key opens the multi-page menu with
the settings for the currently active application. Information about the individual setting possibilities can be
found in the Section describing the particular application.
System settings
I
▼
The system settings are not application-dependent, and apply to the entire weighing system (e.g. setting the
dialog language). To call up the system settings, press the "I" key and then the "System" button. You will
find information on the individual possible settings in Section 5.

4.5
The security system in your balance
Your balance’s system settings, or parts of them, can be protected against unauthorized modifications by means of a password
(detailed information can be found in Section 5.9). A password is defined when the balance is shipped from the factory (see Section
5.9). However, the menu settings are chosen so that you have unrestricted access to all system settings.
If you want to call up part of a menu that is protected by the password, an alphanumeric
keyboard appears on the display.
Type in the password. Observe upper and lower case, using the "a...z" or "A...Z" button
to change case; numerical characters can be entered by pressing the "0...9" button. You
can use the arrow key to delete incorrect input character by character. For security
reasons, the password is not shown in plain text, but the individual characters are
represented by an asterisk.
Note: You can cancel password dialog box at any time by pressing "C".
As soon as you have entered the whole of the password, press "OK". If the password
is correct, the selected menu will appear. Otherwise, an error message will be displayed
together with the prompt to re-enter the password.
WARNING: Note your password very carefully! If you forget the password, there is
no way of recreating access to the protected menu area! We recommend that you
write the password down and store it in a safe place!

Settings for calibration and tests
In these menus you can make all the settings associated with the adjustment (calibration) of your balance.
In the following subsections you will find information on all the possible settings for
adjustment, testing procedures and their recording.
5.3.1
Fully automatic adjustment function "FACT"
You can make the settings for fully automatic adjustment using the internal adjustment
weight in this menu (FACT). FACT (Fully Automatic Calibration Technology) calibrates
the balance under full automatic control on the basis of a pre-selected temperature
criterion.
The following settings are available:
"Off"
Fully automatic adjustment, FACT, is switched off.
"On"
Fully automatic adjustment, FACT, is switched on.
The "Define" button permits you to specify the behavior of the FACT adjustment function:
– "Temperature Criterion" specifies the ambient temperature at which automatic
adjustment should be triggered. If you select "Off", automatic calibration on the basis
of a temperature criterion will not take place.
– "Protocol Trigger" specifies whether an adjustment report should be printed automatically. If you select "Off", automatic printouts will not be made. If "On" is selected,
a record will automatically be printed out whenever the balance undergoes automatic
adjustment as a result of the temperature criterion.
"CalInfo"
Although the FACT temperature criterion is active, automatic adjustment will not take
place when the criterion is met. Instead the icon "CAL" will appear in the upper right area
of the display, prompting the user to carry out manual adjustment, either with the internal
or external adjustment weight.

Specify balance parameters
You can adapt the balance to your specific requirements in these menus. Note: Access to the balance parameters can be protected
by a password (Section 5.9); in this case you will be asked to enter the password when selecting the balance parameters.
In the following subsections you will find information about the individual balance
parameters and about the available settings.
System settings
34
5.4.1
Adaptation to the type of balance
By setting the Weighing Mode you adapt the balance to the weighing type. Select the
"Universal" weighing mode for all ordinary weighing processes, or "Dosing" to dispense
liquid or powder materials. With this setting the balance reacts very quickly to very
small changes in weight. The "Sensor Mode" setting supplies a weighing signal which
is filtered to an extent which depends on the setting for the environmental conditions.
The filter behaves linearly in relation to time (not adaptively) and is suitable for the
continuous processing of measurement values. Under the "Checkweighing" setting the
balance only responds to large changes in weight, and the measurement is therefore
very stable.
Factory setting:
5.4.2
"Universal"
Adaptation to the ambient conditions
With this setting the balance can be ideally adjusted to match the ambient conditions
at its location. If you are working in an environment which is practically free from drafts
and vibrations, choose the "Stable" setting. If, on the other hand, you work in an
environment where the conditions are continuously changing, select "Unstable". The
"Standard" setting corresponds to an average working environment subject to moderate
variations in the ambient conditions.
Factory setting:
5.4.3
"Standard"
Speed of the value release
With this setting you can specify how rapidly the balance considers the measurement
to be stable and therefore releases the value. The "Very fast" setting is recommended
if you require rapid measurements whose repeatability is of lower significance. The "Very
reliable" setting gives measurements that are highly repeatable, but it lengthens the
stabilization time. Three other intermediate settings can be selected.
Factory setting:
5.4.4
"Fast"
Automatic zero setting
Automatic zero setting ("AutoZero") continuously corrects possible variations in the zero
point that might be caused by small amounts of contamination on the weighing pan.
You can use this menu option to switch the automatic zero setting on or off.
Factory setting:
"On" (switched on)
System settings
35
5.5
Select dialog language
In this menu you select the language in which you wish to communicate with the balance.
Factory setting:
5.6
Depends on the language package installed. Usually the
language is preset to that of the country for which the balance
is intended.
Select peripheral devices
A number of different peripheral devices can the connected to the interface(s) of your balance. In this menu you can specify which
device is connected, and with which parameters the interface should operate.
The following settings may be chosen:
– "Printer":
Printer
– "Host":
External computer (bi-directional communication; the
balance can send data to the PC, and can receive
commands or data from it)
– "Secondary Display":
Secondary display
– "Bar Code":
Barcode reader
Specific facilities for adjusting the interface are available for each of these devices: "Off"
means that no device of this type is to be connected. "RS232 built-in" refers to the
RS232C interface fitted at the factory. If other, optional interfaces are present, these are
displayed (as is the second serial interface, "RS232 Option", in the example shown
here). At this point, however, only the parameters for the RS232C interface fitted at the
factory are explained. Important: You can only activate one device for each interface
that is present, and all other devices must be deactivated ("Off"). If you activate a new
device, the previously selected device is automatically deactivated.
System settings
36
If you have activated a device you can adjust the interface parameters for communication
with that device with the "Define" button (baud rate, bit/parity, stop bits, Handshake, end
of line, character set, and continuous mode). The parameters are preset to match the
corresponding optional devices from METTLER TOLEDO.
Note: It is not possible to define interface parameters for the "auxiliary display"; they are
pre-selected.
Factory setting:
"Host"
(9600 baud, 8 data bits/no parity, 1 stop bit, Xon/Xoff
protocol, End of line character <CR><LF>, ANSI/WINDOWS
character set, Continuous mode Off)
Important: To ensure that special characters (e.g. "°C") are printed out correctly on
METTLER TOLEDO printers, Balance and printer must be set to 8 data bits.
Note: For operation with a printer, under “Char Set” the setting IBM/
DOS must be selected.
If under “Host” the built-in RS232C interface has been selected, you can additionally
activate Continuous mode.
In “Continuous mode” you can specify various different data formats (MT–SICS, PM, AT,
MT) depending on which peripheral device is connected. You can also specify the
update rate per second (2, 5, 6, 10).
Factory setting:

5.7
Terminal settings
In this menu you can adapt the terminal to suit your needs and can adjust the display.
The following parameters are available:
"Brightness"
Here you can adjust the brightness of the display. Use the arrow keys to adjust the
brightness between 20% and 100% (in steps of 20%) as required. The brightness is
modified immediately each time either of the arrow keys is pressed, so that you can see
the change straightaway.
Factory setting:
80%
Note: If the balance is not used for 15 minutes, the brightness of the display is
automatically reduced to 20%. This extends the service life of the back illumination. The
brightness is immediately returned to the value that has been selected here as soon as
either a key is pressed or the weight changes.
"Contrast"
Adjusting the display contrast (range of settings 0% – 100% Contrast). The settings
are made in a similar way to those for brightness, but in 2% steps.
Factory setting:
50%
"Sound"
Setting the volume of the beep (setting range 0% – 100% in steps of 10%). Selecting
0% switches the beep off. A slider is provided to make the setting, similar to the
adjustments for brightness and contrast.
Factory setting:
70%
"Touch Function"
If you switch off the "touch screen" function, the display no longer reacts to touch when
in weighing mode, which means that you are no longer able to make settings simply
by pressing the display (exception: function keys). Important: The contact function is
always active in setting mode, since otherwise it would be impossible to make
adjustments.
Factory setting:
"On"
"Touch adjustment"
If you have the impression that the balance is no longer reacting correctly when you
press certain locations on the display, you can adjust the touch screen. After pressing
the "Activate" key a window opens in which you are asked to press the flashing area.
This procedure is repeated a number of times (it is possible to stop at any time by
pressing the "C" key).

Function keys offer you direct access to specific functions and settings for the application. The function keys are shown in the
application on the lower edge of the display (see Section 4.2). The corresponding function is initiated by pressing one of the buttons.
In this menu you can specify which functions should be made available in the application.
The function keys that have a number will be displayed in the application. The numbers specify the sequence of the function keys
on the display. If you activate or deactivate a function key by pressing it, the sequence of the keys is automatically updated. To specify
a completely new sequence, first deactivate all the function keys, then activate them again in the desired sequence. You can return
to the factory setting by pressing "STD". Press "OK" to save the changes (or press "C" to leave the input window without saving).
The following function keys are available.
"ID":
This function key allows you to assign identifiers (descriptive texts) to individual
weighing processes. These will be included in the printouts. After pressing the function
key, a window appears in which you select the ID, after which you can enter the desired
text. You will find information on the definition of the identifiers in Section 6.2.9.
Practical notes on working with identifiers may be found in Section 6.3.3.
"Display":
This function key allows you to switch between three different types of display (Section
4.2).
"Lotcounter":
This function key allows you to enter an initial value for the item counter (Section 6.3.2).

6.2.3
Select information fields
The information fields provide continuous information about set values, measured results and so forth. The information fields are
displayed in the application underneath the weighing result. Note: The information fields are only shown in the display mode in which
the weight itself is represented on a small scale. In the other two display modes, the larger display of the weight uses the space taken
by the information fields (Section 4.2).
In this menu you can specify which information fields should be displayed in the
application.
The information fields that have a number will be displayed in the application. The
numbers specify the sequence of the information fields on the display. Important: For
reasons of space, a maximum of three information fields can be displayed. If you
activate more than three information fields, only the first three will in fact appear on the
display. If you activate or deactivate an information field by pressing it, the sequence
of the fields is automatically updated. To specify a completely new sequence, first
deactivate all the information fields, then activate them again in the desired sequence.
You can return to the factory setting with "STD", while "C" allows you to leave the input
window without saving. If you wish to save your changes, press "OK".
The following information fields are available:
"ID1", "ID2" and "ID3":
These information fields display the identifiers entered by means of the "ID" function key.
Note: The identifiers that have been specified are displayed, not "ID1", "ID2" and "ID3"
(Section 6.2.9).
"Info Unit":
This information field displays the weghing result in the second weighing unit that you
have chosen (Section 6.2.5).
"Tare":
This information field displays the current tare value (in the same unit of weight as the
weighing result in the main display).
"Gross":
This information field displays the current gross weight (in the same unit of weight as
the weighing result in the main display).
Factory setting:
6.2.4
No information fields are activated.
Selections for automatic printouts
With this menu option you can specify whether the weighing result should automatically be printed out.
"Off":
The weighing result is not automatically printed out, and the "F"
key must be pressed to print the result.
"On":
The weighing result is automatically printed out, provided the net
weight is of at least a certain value. The information that is printed
out is what you have specified for printing individual values
(Section 6.2.7).
Factory setting:
"Off".

6.2.5
Select weighing units
You can specify the weighing units with which you want to work in the "Display Unit" and "Info Unit" menus. If two different units are
chosen, you can have the weighing result displayed in two different weighing units at the same time.
The same range of units can be selected for the "Display Unit" as for the "Information
Unit".
If the "Display Unit" is changed, both the current measured weight and the values
displayed in the "Tare" and "Gross" information fields (Section 6.2.3) appear in the
new weighing unit.
The "info Unit" is used for the information field of the same name (Section 6.2.3).
Factory setting:
6.2.6
Depends on the model (for both units).
Define freely selectable weighing units
You can define your own weighing unit in the "Custom Unit" menu. This permits calculations to be carried out immediately the
weighing result is found (e.g. for surface areas or volumes). The freely selectable weighing unit is available in all the menus and
input fields where weighing units can be chosen.
The following fields are available in order to define the freely selectable weighing unit:
"Formula":
This is where you can specify how the value which will be specified below under "Factor"
is to be applied to the calculation. Two formulas are available, in which "F" represents
the factor, while "Net" represents the value of the weighing result. In the first formula,
the net weight is multiplied by the factor, whereas in the second formula the factor is
divided by the net weight. The formula can, for instance, be used to compensate
immediately for a known error factor in the weight determination.
"Factor (F)":
Here you can specify the factor (>0…max.10 000 000) that is to be used to modify
the (net) weighing result (in accordance with the previously selected formula).
"Name":
Enter a name for your free weighing unit (max. 4 characters). Note: It is not permitted
to enter weight units ("g", "kg", etc.), and these will be rejected with an error message.
"Result Output.Form":
You can specify the formatting of the weighing result here. Example: A setting of "0.05"
defines two decimal figures rounded to the nearest 5 (this would mean that a measured
result of 123.4777 would be displayed as 123.50). Note: This function can only be
used to reduce the readability of the results. Do not enter a value that exceeds the
maximum readability of your balance!
Factory setting:
No free weighing unit is defined ("Off")

6.2.7
Define printout
In this menu you can specify the information that is to appear on the weighing printout.
For the sake of clarity, this large menu is divided into three submenus in which you can
specify the options for the printout header, the printing of the individual values, and for
the footer.
Options for the printout header
In this submenu you can specify the information that is to be printed at the top of the
weighing printout (before the results themselves). The header will automatically be
printed if it is defined as an element of the weighing printout (see "Options for printing
out the individual values" overleaf). It can, however, also be printed out separately by
pressing the "Header" function key. Refer to the sample printout illustrated here.
You can activate the desired information by pressing the appropriate boxes. Those items
of information that have a tick will be printed out. You can return to the factory setting
with "STD", while "C" allows you to leave the input window without saving. If you wish
to save your changes, press "OK".

Define identifier
In this menu it is possible to activate the three identifiers that are available under the "ID" key (Section 6.2.2) and to change their
names.
Select the ID that you wish to activate or deactivate, or whose name you want change.
Note: Deactivated IDs ("Off") are no longer available for selection under the "ID" function
key.
A window then appears in which you can activate the ID and change the name.
At the factory, the IDs are pre-set with the names "ID1", "ID2" and "ID3". You can replace
these with your own names, such as "Customer" for "ID1", "Order" for "ID2" and "Batch"
for "ID 3".
Press the associated button in order to change the current name of an ID. An
alphanumeric input field will appear where you can type the new name (max. 20
characters). The ID is then available, with its new name, under the "ID" function key.
The names that have been entered also appear as the titles of the relevant information
fields (Section 6.2.3), and are also included on the printout (Section 6.2.7).
Notes on working with identifiers may be found in Section 6.3.3.

6.3
Working with the "weighing" application
You have already seen in Section 3 how a simple weighing process is carried out. In this Section we will show you how the various
functions in the "Weighing" application can be used in practice.
6.3.1
Changing the readability of the measured weight
The balance is factory adjusted so that the measured weight is displayed with the maximum readability of which the particular model
is capable (according to 1d). You can change the readability of the measured weight at any stage in your work.
To change the readability of the measured weight, the corresponding function key must
be activated (Section 6.2.2). This function key allows you to display the readability with
only one tenth of the precision, i.e. with one less decimal point.
6.3.2
Working with the item counter
The item counter inserts a number in front of every weight value on a printout, and this number is automatically increased by 1 with
every printout.
It is necessary to activate the associated function key in order to work with the item
counter (Section 6.2.2).
When you press this function key, a numerical input field appears in which you can
specify the initial value for the item counter. The value is preset to 0 at the factory, which
means that the item counter is switched off. If you want to start the item counter, enter
an initial value in the range 1 ... 999.
6.3.3
1 N
35.87115 g
2 N
60.24646 g
3 N
80.4896
g
Every time the "F" key is used to print out the results of a weighing, an item counter
is added in front of the weight values, and this counter is increased by 1 with every new
printout. When the counter reaches the maximum value of 999, numbering starts again
at 1.
Note: The item counter also functions in connection with automatic printouts (Section 6.2.4).
Working with identifiers
Identifiers are texts that describe individual weighing procedures. They make it easy to assign weighed materials to particular orders
or customers. The identifiers are included on the printouts (or are transmitted to a connected computer).
It is necessary to activate the "ID" function key in order to be able to work with identifiers
(Section 6.2.2). This function key allows you to call up the available identifiers, of which
there may be up to three. Note: If the IDs are deactivated, the function key is shown in
gray, and pressing it has no effect. In that case it is necessary first to activate the IDs
(Section 6.2.9), before you can use the identifiers.
The three identifiers are named "ID1", "ID2" and "ID3" at the factory. You can replace
these names with more meaningful titles appropriate to your particular application
(Section 6.2.9). The names you have chosen (such as "Customer" for ID1, "Order" for
ID2 and "Batch" for ID3) are then available under the "ID" function key.
The "Weighing" application
53
We recommend that the corresponding information fields are also activated when
working with identifiers (Section 6.2.3). The information fields have the names that you
have selected for the three identifiers.
The example here illustrates the balance’s display after activation of the ID function key
and the ID information fields.
The working example here is based on ID names as defined in the example above.
If you want to carry out an order for a customer in the application, press the "ID" function
key. You can then select the identifier for which you want to enter text (e.g. "Customer").
A field appears where you can enter the customer name (see diagram here). Enter the
name, and confirm your entry with "OK".
After pressing the "ID" function key and selecting the "Order" ID, a similar field appears
where the order name can be entered. The batch name can be entered after you have
pressed the "ID" key and selected the "Batch" ID. Each identifier can be up to 20
characters long.
When all the entries are complete, you can check the selected identifiers again through
the information fields on the display.
All the identifying texts are stored until they are replaced by new ones.

If you have defined the weighing printout in such a way that the identifiers are included
in the printout (Section 6.2.7), then both the ID names that you have specified (e.g.

printed. The illustration here shows a printout including identifications in accordance
with the example above.

6.4
Adjust the balance and check the adjustment
Your balance is factory set to fully automatic adjustment, FACT. FACT adjusts and linearizes the balance automatically as soon as
this is made necessary by a change in the ambient temperature. You can, however, carry out a manual adjustment and/or check
using the internal weight or an external weight at any time.
It is assumed in the following descriptions that the appropriate function keys for adjustment and tests (Section 6.2.2) have been
activated.
6.4.1
Fully automatic adjustment FACT
FACT adjusts and linearizes your balance automatically in accordance with a specified temperature criterion (Section 5.3.1).
As soon as the specified temperature criterion is satisfied, the small FACT icon appears
in the top right-hand corner of the display. The balance indicates in this way that it wants
to carry out a FACT adjustment. Note: during the first 24 hours following connection to
the mains, FACT will execute a number of times, regardless of what criterion has been
selected.
As soon as any load has been removed from the balance, and assuming that a key is
not pressed for a period of 2 minutes, the adjustment automatically begins. A window
appears in the course of the adjustment, informing you about the progress of the
calibration. If you are working with the balance at the time of the adjustment, you can
stop FACT with the "Cancel" button. The balance will carry out the adjustment at the next
opportunity.
When the adjustment has been completed, the balance returns automatically to the
application. Every FACT adjustment is recorded on a printout automatically in accordance with the settings you have made (Section 5.3.1). What information is also included
in addition to the adjustment data depends on the settings you have made for
adjustment and test printouts (Section 5.3.4). You will find a sample printout in Section
6.4.6.
6.4.2
Adjustment with the internal weight
Pressing this function key triggers an adjustment of the balance using the built-in
adjustment weight. You can do this at any time; you can also specify in the system
settings that the balance requests adjustment as soon as a specified change in ambient
temperature has taken place ("CalInfo" setting, Section 5.3.1).
You can hear motors moving the internal weight into place and removing it again. The
window shown here is displayed during the adjustment. The icons are animated, so that
you can visually follow the adjustment process. You can halt the adjustment process
at any time by pressing the "Cancel" key.
The "Weighing" application
55
One of the two following messages will appear when the process is complete:
The adjustment has been successfully completed. Press "OK" to return to the
application.
If a printer is connected to the balance the adjustment will automatically be recorded on
a hard copy in accordance with the specifications that you have made for printing out
adjustments in the system settings (Section 5.3.4). You will find a sample printout in
Section 6.4.6.
An error occurred during the adjustment, and the process was aborted. This message
will also appear when you have cancelled the adjustment yourself. You can repeat the
adjustment procedure, or can return to the application by pressing "OK".
6.4.3
Adjustment with an external weight
Pressing this function key triggers an adjustment of the balance using an external
adjustment weight. You can do this at any time; you can also specify in the system
settings that the balance requests adjustment as soon as a specified change in ambient
temperature has taken place ("CalInfo" setting, Section 5.3.1). Note: Depending on
regulations that vary from country to country, adjustment with an external weight may
not be available on certified balances.
If there is a weight on the weighing pan at the time of the adjustment, the flashing display
"0.00000g" prompts you to remove it. You will then be prompted to place the
adjustment weight on the pan. The required adjustment weight is indicated at the lower
edge of the window.
Important: Make sure that you place the correct weight on the pan, otherwise the
adjustment process will be aborted with an error message. The adjustment weight can
be specified in the system settings (Section 5.3.2).
Note: You can halt the adjustment process at any time with the "Cancel" key.
The adjustment process continues automatically once the required weight has been
placed on the pan. The window shown here is displayed during the adjustment.
The "Weighing" application
56
At the end of the adjustment procedure, you are prompted to lift off the weight. Remove
the adjustment weight from the weighing pan.
The balance confirms successful completion of the adjustment. Press "OK" to return to
the application.
If a printer is connected to the balance the adjustment will automatically be recorded on
a hard copy in accordance with the specifications that you have made for printing out
adjustments in the system settings (Section 5.3.4). You will find a sample printout in
Section 6.4.6.
If an error occurs during the adjustment process, a corresponding error message
appears similar to that for adjustment using the internal weight (see previous section).
6.4.4
Checking the adjustment with the internal weight
You can use the internal weight to check the correct adjustment of your balance by
pressing this function key.
The checking procedure is similar to that used for adjustment with the internal weight
(Section 6.4.2).
Successful completion of the checking process is confirmed with the window shown
here. If a printer is connected to the balance the check will automatically be recorded
on a hard copy in accordance with the specifications that you have made for printing
out checks in the system settings (Section 5.3.4). You will find a sample printout in
Section 6.4.6.
An appropriate message appears if the checking process is aborted as a result of an
error.
6.4.5
Checking the adjustment with an external weight
You can an external weight to check the correct adjustment of your balance by pressing
this function key.
The checking procedure is similar to that used for adjustment with an external weight.
After completion of the check a message appears similar to that for checking the
adjustment using the internal weight. If a printer is connected to the balance the check
will automatically be recorded on a hard copy in accordance with the specifications that
you have made for printing out checks in the system settings (Section 5.3.4). You will
find a sample printout in Section 6.4.6.

The "Statistics" application
In this Section we describe the "Statistics" application. You will find information here about practical aspects of working with this
application and about its specific settings. (Information about the system settings that are not specific to the application are to be
found in Section 5.)
7.1
Introduction to the "Statistics" application
The "Statistics" application basically offers the same facilities as the "Weighing" application, but contains additional settings and
functions for the statistical recording and analysis of weighing series.
Many of the application-dependent settings are identical to those of the "Weighing" application. Additional function keys and
information fields are nevertheless available for the statistics. Only those settings will be explained in detail in the following
descriptions that are different from those of the "Weighing" application.
7.2
Select the application
Unless the "Statistics" application is already active, press the "I" key. Press the icon
for the application in the selection window.
I
The following display appears when the application has been selected. The special
function keys and information fields for statistics are activated under the factory settings.
You can adapt the settings to your own requirements as described in the following
Sections.
Notes: If the information fields are not displayed on your balance, press the "Display"
function key to reduce the size of the display of the weight, and thereby provide space
for the information fields to be shown.
The two function keys for "Result" and "CL Result" appear in gray because at this stage
the statistical functions do not contain any values.
7.3
Settings for the "Statistics" application
A number of different specific settings are available for the Statistics, and these can be used to adapt the application to suit your needs.
7.3.1
Overview
J
The application-specific settings can be accessed via the "J" key. The first of a total of
four menu pages appears after pressing this key.
The "Statistics" application
59
Apart from a small number of exceptions, the settings available for the "Statistics" application are identical with those for the
"Weighing" application (Section 6.2). The only differences in the settings are described below. These concern the following menus:
"Function Keys":
Additional function keys are available for
the Statistics.
"Info Field":
Additional information fields are available
for the Statistics.
"Protocol":
Additional printout information is available
for the Statistics.
"Additive Mode":
In this menu, which is only available in the
"Statistics" menu, you can activate the
additive mode (series weighing with
automatic taring).
In the following Sections we will present the specific settings for the "Statistics" application in detail.
7.3.2
Special function keys for statistical purposes
The following settings are available in the function key menu for use with the statistics system:
"M+":
This function key passes the current stable weight to the statistics
system (Section 7.4.1).
"Result":
This function key opens the statistics window (Section 7.4.1).
"CL Result":
This function key deletes the statistics from a series of weighings
(Section 7.4.1).
"CL last":
This function key clears the most recently saved measurement
(Section 7.4.1).
"Nominal":
You specify the desired target weight with this function key
(Section 7.4.2). The target value is also used as a reference for
the tolerances (described below).
"+Tol" and "–Tol":
You can specify with these function keys the precision (tolerances)
with which you want the weighing to be carried out (Section 7 .).
"Max n":
You specify the maximum number of samples in a series with
this function key (Section 7.4.1).
All the remaining function keys correspond to those for the "Weighing" application
(Section 6.2.2).
Factory setting:
"M+", "Result" , "CL Result" and "Display" are active (in that
sequence).
The "Statistics" application
60
7.3.3
Special statistical information fields
The following settings are available on the first two pages of the information fields menu for the display of statistical values:
"n":
Number of samples weighed.
"x":
Mean weight of all samples.
"s" and "s.rel":
Standard deviation as an absolute or as a percentage figure.
"Sum":
Summed weight of all the individual weighings.
"Min" and "Max":
Smallest and largest weights found in the current series of
weighings.
"Diff":
Difference between the smallest and largest measured weights.
"Nominal":
Indicates the target value that has been entered through the
function key with the same name.
"+Tol" and "–Tol":
These information fields display the tolerances that have been
entered through the function keys with the same names.
All the information fields keys correspond to those for the "Weighing" application
(Section 6.2.3).
Factory setting:
7.3.4
"n", "x" and "s" are activated (in this sequence).
Special printout information for statistical purposes
Additional settings for statistics, described below, are available in the three submenus
in which you can specify the options for the printout header, for printing the individual
values, and for the result.
Note: The remaining available printout information corresponds to that for the "Weighing"
application (Section 6.2.7), and is not described here.
The printout header
Additional settings for statistics are available on the second page of this submenu:
"Max n":
Prints the specified maximum number of samples in the series.
"Nominal":
Prints the specified target weight.
"+Tol" and "–Tol":
The specified tolerances are printed.
Factory setting:
"Appl. name" ("Statistics" is printed); thus no specific statistical
information is activated.
The header is automatically printed when the "M+" key is pressed during a series of
weighings in order to pass the first measured weight to the statistical system. The header
can also be printed separately by pressing the "Header" function key.
The "Statistics" application
61
Printing the individual values
The same additional settings are available in this sub menu as are provided for the
header: ("Max n", "Nominal value", "+Tol" and "–Tol").
Factory setting:
"Net" (the net weight of the current weighing). No specific
statistical information is activated.
An individual value is automatically printed when the "M+" function key is pressed
during a series of weighings. An individual value can, however, also be printed out
separately by pressing the "F" function key.
Printing the result
You specify the additional statistical information that is to be included in the result
printout in this sub menu:
"Max n":
The specified maximum number of samples in the series.
"Nominal":
The specified target weight.
"+Tol" and "–Tol":
The specified tolerances.
"n":
Number of samples weighed.
"x":
Mean weight of all samples.
"s" and "s.rel":
Standard deviation as an absolute or as a percentage figure.
Note: These two values are only printed if the statistical system
contains at least three values; otherwise horizontal bars are
displayed instead of the values.
"Min" and "Max":
Smallest and largest weights found in the current series of
weighings.
"Diff":
Difference between the smallest and largest measured weights.
"Sum":
Summed weight of all the saved individual weighings.
Factory setting:
"n", "x", "s", "s.rel", "Min", "Max", "Diff" and "Sum". The
"Signature" and "3 Blank Lines" settings are also active
(Section 6.2.7).
These results are printed when the "F" key is pressed while the statistics window is
open. If a specific number of samples has been defined for a series of weighings ("Max
n") the results are printed automatically as soon as the value of the weight of the last
sample has been passed to the statistics system using the "M+" key.
Note: "Max n", "Nominal value", "+Tol" and "–Tol" are included on the printout of results,
but are not displayed in the statistics window.
You will find a sample printout with statistical values in Section 7.4.3.
The "Statistics" application
62
7.3.5
Activate additive mode
In this menu, which is only available in the "Statistics" application, you can switch the additive mode on or off. In weighing series
made with the additive mode active you do not have to remove the samples from the weighing pan.
"Off":
Additive mode is switched off.
"On":
Additive mode is switched on. The result of weighing a sample
is passed to the statistical system by pressing the "M+" function
key, after which the balance is automatically tared. The next
sample can be weighed without having to remove the previous
samples from the weighing pan.
Factory setting:
7.4
"Off".
Working with the "Statistics" application
In this Section you will learn how to work with the "Statistics" application. It is of course possible to specify a tare, modify the readability
of the measured weight, use identifiers and so forth. You will already be familiar with these facilities from the "Weighing" application
(Section 6.3), and they will therefore not be explained again here.
7.4.1
Statistical recording of series of weighings
Default settings
At least the three function keys shown here must be activated for you to be able to use
the statistics (Section 7.3.2).
It is also recommended that the two function keys opposite are activated. They allow
incorrect values to be deleted ("CL Last") and the number of samples that should be
included in a series of measurements to be specified ("Max n").
A printer should be connected to your balance to make best use of the statistical
functions. If this is not the case, we recommend that you activate the three information
fields that will be most important for your application (e.g. "n", "x" and "Sum". See
Section 7.3.3).
Note: Once a statistical series has been started, changes to the weighing unit are
restricted. If the statistical series uses the “Free Unit”, the unit cannot be changed. If the
statistical series uses a “Weight Unit”, a change within the weight units is possible.
Operating sequence
If the number of samples that is to be weighed for a series is already specified, you can
press the "Max n" function key and enter the number of samples (max. 99). The series
is automatically completed after the last sample has been weighed, the statistical
window is opened, and the results are printed out. Notes: This function key is only active
as long as the statistical system does not contain any measurements. The series is
unlimited if you enter the value 0 (zero) for "Max n", and you can weigh up to 99
samples.
If you are working with a weighing container, place this on the balance and press the
"H" to tare the balance.
The "Statistics" application
63
Place the first sample on the balance, and press the "M+" function key to pass the weight
to the statistical system. As soon as the value of the weight is stable (horizontal bars
disappear in the display) the value is passed to the statistical system. The header is
printed out together with the result (the single value) of the current weighing (Section
7.3.4).
Remove the first sample. Note: If you have activated Additive Mode (Section 7.3.5) you
can leave the sample on the weighing pan, because the balance will automatically be
tared after the "M+" function key has been pressed.
Place the other samples on the balance in turn. Confirm each weighing with the "M+"
function key, lift the sample off and tare the balance (not necessary if additive mode was
active). Each time "M+" is pressed the individual value that has been found is
automatically printed.
Notes
– An error message appears if you press the "M+" key without the weight having
changed. This prevents the same sample from being measured twice.
– If you have accidentally placed an incorrect weight on the balance and saved the
result of the weighing you can delete the most recent value with the "CL Last" function
key (only available when values have been saved, otherwise the key appears gray
and cannot be activated). Once a value has been deleted the key becomes inactive,
and will only work again after the next value has been passed to the statistical
system.
When all samples have been weighed, press the "Result" function key (only available
when values have been saved; otherwise the key appears gray and it cannot be
activated). This temporarily halts the measurement process and opens the statistical
window. (You can, however, continue the series at any time). Note: If the "Max n"
function key was used before weighing started to specify the number of samples, then
when the last sample has been weighed the statistical window will open automatically,
with the comment that the maximum number of samples has been reached.
The statistical window contains the result of the series of weighings. (The information
that you selected for printing the result is displayed, see Section 7.3.4). Please note the
information in Section 7.4.3 regarding units, readability and the precision of the
displayed values.
The arrow keys allow you to switch between the individual screen displays. You can print
the result by pressing the "F" key.
You will find a complete sample printout with statistical values in Section 7.4.3.
If you are sure that you want to complete the measuring procedure and clear the memory
for a further series, press the "CL Result" function key. (For security reasons you will
be prompted to provide confirmation before the statistics are actually deleted.) Note: If
the button appears gray it is because the statistical system does not contain any values.
The "Statistics" application
64
7.4.2
Additive weighing to a target value
The "Statistics" application provides you with additional functions that make it easier to perform additive weighing up to a specified
target value. When using the statistics, you can apply these functions both to individual weighings and to series weighings.
Default settings
The function keys shown here must be activated so that you can enter a target value and
the associated tolerances (Section 7.3.2). If desired, you can also activate the
information fields with the same names so that the values that have been specified are
visible on the display (Section 7.3.3).
Operating sequence
Note: If the statistical system already contains values, the function keys with which the
target value and the tolerances can be entered are not active. In that case you must clear
the statistics using the "CL Result" function key before you can specify the target value
and the tolerances.
Press the "Nominal " function key to enter the desired target weight. Type in the desired
target value. (If there is already a weight on the balance that matches the target weight,
you can adopt this directly by pressing the button with the balance icon). Check the
weighing unit, which is displayed to the right of the target value. Pressing the weighing
unit will cause a list of the available units to appear. Note: The units are not
automatically converted; if you have entered a value in one unit, this value is retained
even when you change the weighing unit.
Press "OK" after you have entered the value to activate the target weight.
You can use the two "+Tol" and "–Tol" function keys to specify the precision to be used
for the weighing. The input window is the same as that for the target value. Both
tolerances are set at the factory to 2.5%.
After the appropriate value has been entered, press "OK" to activate the tolerance.
Note: Samples whose measurement is outside the tolerance are specially marked when
the individual values are printed out (with ">T" or "<T" respectively).
As soon as you have entered the target value and the tolerances the graphical filling
guide ("SmartTrac") appears. This displays tolerance marks that make it easier for you
to weigh up to the target value: You can add roughly the right amount of material until
the lower tolerance value has been reached, and then, if necessary, make careful
additions to reach the target value.

The diagram opposite shows a sample printout with statistical values. The values that
are printed in the header, as individual values, and as the result depend on the individual
printout settings that you have made (Section 7.3.4).
Only the statistical information in the illustrated sample printout is explained below. You
will find notes on the other printout information in Section 6.2.7:
"Nominal":
The specified target weight.
"+Tol":
The specified positive tolerance.
"–Tol":
The specified negative tolerance.
"n":
The number of samples weighed.
"x":
Mean weight of all samples. The value is printed in the current
display unit. The readability of the printed values is 10 times
greater than those of the measurements with the highest readability
within the series of measurements.
"s":
The standard deviation within the series. The value is printed in
the current display unit. The readability of the printed values is 10
times greater than those of the measurements with the highest
readability within the series of measurements.
"s.rel":
Relative standard deviation within the series (in percent). The
value is always printed with 2 decimal figures.
"Min":
The lowest weight found in the current series of measurements.
The number of decimal points and the unit match those of the
values that were visible when the measurement was transferred
to the result.
"Max":
The largest weight found in the current series of measurements.
The number of decimal points and the unit match those of the
values that were visible when the measurement was transferred
to the result.
"Diff":
The difference between the smallest and the largest weights
found in the current series of measurements. The value is printed
in the current display unit. The number of decimal points in the
printed value matches those of whichever of the smallest or
largest weight has the highest readability.
"Sum":
The sum of all the individual weights that have been stored. The
value is printed in the current display unit. The number of decimal
figures matches that of whichever value in the series of
measurements has the highest readability.
Signature
........................
Important information on interpreting the printed results
The values for "x" and "s" are the results of calculations, and are displayed with a higher
readability than that of the individual measurements. If the series of measurements is
small (less than about 10 measurements), or if the series has small variations, the
significance of the last decimal figure cannot be guaranteed.

7.4.4
Formulas used for calculating statistical values
Calculating the mean value and standard deviation
Terminology
xi := Individual measurement values of a measurement series of n measurement values i = 1...n
x := Mean value and s standard deviation of these measurement values
The formula for calculating the mean value is:
x=
1 n
∑ xi
n i =1
(1)
The usual formula for calculating standard deviation, as seen in the literature s
s=
(
1
∑ xi − x
n −1
)
2
(2)
is not suitable for numerical calculation, since the variance (individual value-mean value) can result in deletion in measurement series that
have very small deviations. Moreover, when this formula is used, each individual measurement value must be stored before the standard
deviation can be determined at the end.
The following formula is mathematically equivalent but significantly more stable numerically. It can be derived from (1) and (2)
through appropriate recasting.
s=+
2

x
x
−


∑ i
∑ i 
n − 1  i =1
n  i =1  
To use this formula for calculating the mean value and the standard deviation, you just need to store n, ∑ xi and ∑ xi .
2
Standard deviation
Numerical stability can be improved even more by scaling the measurement value:
With ∆xi := xi − X 0 , where X 0 (depending on the application) is either the first measurement value of a measurement series or the
nominal value of a measurement series, the result is:
2
1  n
1 n
 
2
s=+
∑ (∆xi ) −  ∑ ∆xi  
n − 1  i =1
n  i =1
 
Mean value
The mean value is then calculated as follows:
x = X0 +
1 n
∑ ∆xi
n i =1
Relative standard deviation
The relative standard deviation is calculated by means of the following formula:
s
srel = 100 percent
x
Number of digits in the results
Mean value and standard deviation are always expressed and displayed to one more decimal place than the corresponding individual
measurement values. When interpreting the results, keep in mind that the additional decimal place is not meaningful when it comes
to small measurement series (less than approx. 10 measurement values).
The same is also true of percentages (such as those used in expressing relative standard deviations), which are always shown to
two decimal places (for example, 13.45 percent). Here, too, the significance of the decimal places depends on the size of the
background data.

The "Formulation" application
In this Section we describe the "Formulation" application. You will find information here about practical aspects of working with this
application and about its specific settings. (Information about the system settings that are not specific to the application are to be
found in Section 5.)
8.1
Introduction to the "Formulation" application
The "Formulation" application allows you to weigh in the components of a Formulation up to a specific target weight. The values of
each component (target weight, tolerances, difference from target weight, etc.) can be stored, and after all the components have been
weighed in a Formulation record can be printed out.
Many of the application-dependent settings are identical to those of the "Weighing" application. Additional function keys, information
fields and printout information are, however, available for Formulation purposes. Only those settings will be explained in detail in
the following descriptions that are different from those of the "Weighing" application.
8.2
Select the application
Unless the "Formulation" application is already active, press the «I» key. Press the icon
for the application in the selection window.
I
The display opposite appears when the application has been selected. The special
function keys for Formulation are activated under the factory settings. You can adapt
these and other settings to your own requirements, as described in the following
Sections.
Notes: If the graphical filling guide ("SmartTrac") is not displayed on your balance,
press the "Display" function key which will reduce the scale on which the weight itself
is displayed, providing space for the filling guide.
The two function keys for "Result" and "CL Result" are displayed in gray, since no
Formulation has yet been carried out.
8.3
Settings for the "Formulation" application
A number of different specific settings are available for Formulation, and these can be used to adapt the application to suit your needs.

8.3.5
Special identifiers for Formulation
In this menu you specify the names for the three identifiers that are available during Formulation under the "ID" function key.
The factory setting for these three identifiers have the following names:
"ID1"
"ID2"
"ID3"
"Recipe ID"
"Comp. ID"
"Lot ID"
You can deactivate individual identifiers, or can replace their names with your own text
(max. 20 characters).
The names that have been entered also appear as the titles of the relevant information
fields (Section 8.3.3), and are included on the printout (Section 8.3.4).
Factory setting:
8.4
"ID1" and "ID2" active, see above for names
Working with the "Formulation" application
In this Section you will learn how to work with the "Formulation" application and to print the results.
8.4.1
Default settings
At least the three function keys "M+", "Result" and "CL Result" must be active for
Formulation (Section 8.3.2).
The "ID" function key should also be active, so that you can assign the names you want
to your formulas and components.
If you want to weigh your components to within a particular tolerance up to a target
weight, you must also activate the "Nominal", "+Tol" and "–Tol" function keys.
We also recommend that the "Abs/Diff" function key is activated, so that you can switch
the display at any time between the quantity of a component that has already been
weighed in and the quantity that still has to be added.
A printer should be connected to your balance to print out Formulations. If this is not the
case, we recommend that you activate the three information fields that will be most
important for your Formulation application (e.g. "Nominal", "ID1" and "ID2", see
Section 8.3.3).
The "Formulation" application
72
8.4.2
Operating sequence
If you are working with a weighing container, place this on the balance and press the «H», to tare the balance.
Press the "ID" function key and enter the desired names (for the formula, for the first
component and, if ID3 is active, also for the current lot).
If you want to weigh up to a target value, press the "Nominal" function key, and specify
the target weight for the first component.
Note: If you have changed the display to show the remaining amount (difference) before
entering the target weight using the "Abs/Diff" function key, the target weight will appear
on the display with a negative arithmetic sign (the difference between the weight and
zero).
If you are using tolerances, enter the appropriate values using the "+Tol" and "–Tol"
function keys. (Samples that lie outside the tolerance band are marked with ">T" or "<T"
on the printout of individual values.)
As soon as you have entered the target weight and the tolerances for the first component,
the graphical filling guide ("SmartTrac") appears. This displays tolerance marks that
make it easier for you to weigh up to the target value.
Weigh in the first component.
Note: You can switch the display of the weight at any time between the quantity of the
components that has already been weighed in and the remaining quantity that still has
to be added with the "Abs/Diff" function key.
When the target weight has been reached, or the weight is within the tolerance band,
press the "M+" function key to save the value. The header is printed out together with
the single value of the current component (Section 8.3.4).
The balance is now ready for the second component to be weighed in. If you want to
weigh the second component into the same container, it is not necessary to tare the
balance.
If you wish to weigh the second component into a new weighing container, remove the
weighing container with the first component and wait until the balance has settled to
zero. Now put the new container in place, and tare the balance.
Specify the names (IDs) and values (target value, tolerances) for the second component,
weigh the component in, and save the result with the "M+" function key.
Weigh in the other components as described above. Each time "M+" is pressed the
individual measured value is printed in accordance with your specifications (Section 8.3.4).
When all the components in the formula have been weighed, press the "Result" function
key (only available when values have been saved; otherwise the key appears gray and
it cannot be activated).
The "Formulation" application
73
After you have pressed the "Result" function key, three results are displayed: "Nominal
Tot.", "Comp. Counter" and "Net Tot.". They will, however, only be displayed if you have
selected these settings (Printing the results, Section 8.3.4).
You can print the complete result by pressing the «F» key.
You will find a complete sample printout in Section 8.4.3.
If you are sure that you want to complete the Formulation procedure and clear the
memory for a further Formulation, press the "CL Result" function key. (For security
reasons you will be prompted to provide confirmation before the memory is actually
cleared.)

The "Density" application
In this Section we describe the "Density" application. You will find information here about practical aspects of working with this
application and about its specific settings. (Information about the system settings that are not specific to the application are to be
found in Section 5.)
9.1
Introduction to the "Density" application.
The "Density" application allows the density of solid objects, liquids and pastes to be found. An identifier can be assigned to every
sample, and the integrated statistic functions permit statistical analysis of series of measurements. The density is determined
exploiting the principle of Archimedes, which states that any body immersed in a fluid becomes lighter by an amount equal to the
weight of the fluid that it has displaced.
You can use your balance’s hanger (for weighing below the balance) to carry out density determinations (Section 2.8). We
recommend , however, that to find the density of solid objects you make use of the optional density kit; this contains all the necessary
fittings and auxiliary equipment for convenient, accurate density measurements. The density kit has a separate set of instructions
which explain how it is installed and used.
To determine the density of liquids you also need a sinker, and this too can be obtained from your METTLER TOLEDO dealer. A gamma
sphere will also be needed to determine the density of pastes; your dealer will be glad to tell you where one can be obtained.
Follow the instructions that are included with these accessories; they contain useful information on how to work with these aids, how
to handle them and how to look after them.
9.2
Select the application
I
Unless the "Density" application is already active, press the "I" key. Press the icon for
the “Density” application in the selection window.
The following display appears when the application has been selected. Special function
keys and information fields for density are activated under the factory settings. The
balance is preset to determine the density of solid objects using water as the auxiliary
liquid. You can adapt these settings to your own requirements, as described in the
following Sections.
Note: If the information fields are not displayed on your balance, press the "Display"
function key to reduce the size of the display of the weight, and thereby provide space
for the information fields to be shown.
9.3
Settings for the "Density" application
A number of different settings are available for density determination, and these can be used to adapt the application to suit your needs.
9.3.1
Overview
J
The application-specific settings can be accessed via the "J" key. The first of a total of
four menu pages appears after pressing this key.
The "Density" application

You specify the auxiliary liquid that you want to use in this menu. This setting is only of significance when determining the density
of solid bodies! The following auxiliary liquids are available:
"Water":
The density of distilled water at various temperatures (from 10°C
up to 30°C) is stored in the balance.
"Ethanol":
The density of ethanol at various temperatures (from 10°C up to
30°C) is also stored in the balance.
"Others":
Any other liquid. Its density at the current temperature must be
known.
Factory setting:
"Water" is set as the auxiliary liquid.
The "Density" application
76
9.3.4
Activate or deactivate the statistics
The balance can maintain its own statistics for each method of density determination with the results of the density determinations
which have been transferred into the statistics (max. 651500). If the statistics are activated, then at the end of each density
determination you will be asked whether you want to add the results to the statistics. You can activate or deactivate the statistical
function in this menu:
"On":
The statistical function is active.
"Off":
The statistical function is not active.
Factory setting:
The statistical function is not active ("Off").
Note: You must also activate the two associated function keys in order to make use of
the statistics (Section 9.3.6). You will find information on working with the statistics in
Section 9.5.
9.3.5
Specifications for calculating and displaying the result
You specify in this menu the number of decimal figures and the unit in which the result of the density determination is to be calculated
and displayed. You also specify whether atmospheric buoyancy should be included in the calculation.
"No. of Decimalpoints":
The result of the density determination can be displayed
and printed with between 1 and 5 decimal figures.
"Compensation":
The result of the density determination can be corrected
using a correction factor that allows for the force calibration
and for the mean atmospheric density (setting "With").
There is no compensation if "Without" is set. Both the
corrected and the uncorrected results are displayed and
printed if the "With/Without" setting is chosen.
"Density Unit":
You can specify the unit to be used for the density
determination here: "g/cm3", "kg/m3" or "g/l" (grams per
liter).
Factory setting:
9.3.6
Number of decimal figures:

Special function keys for density determination
Additional settings are available in the function key menu for density determination:
"Start":
You can start the density determination with this function key, and
it is therefore essential that this key is active!
"Density AL":
You can enter the density of the auxiliary liquid with this function
key. This key is only necessary when determining the density of
solid bodies and when the auxiliary liquid being used is neither
water nor ethanol.
"Temp. AL":
You can enter the temperature of the auxiliary liquid with this
function key. This key is only required when distilled water or
ethanol are being used, since for any other liquid it is necessary
to enter the density at the current temperature. When methods
that do not employ an auxiliary liquid are being used, the key can
be used to enter the current ambient temperature so that this
appears on the printouts.
The "Density" application
77
"Vol. Sinker":
The volume of the sinker can be entered with this function key
(in g/cm3, max. 5 decimal figures). You only need activate this
key if you want to use a sinker to determine the density of liquids.
"Vol. Gamma":
The volume of the gamma sphere can be entered with this
function key (in g/cm3, max. 5 decimal figures). You only need
activate this key if you want to use a gamma sphere to determine
the density of pastes.
"Result":
You can display the statistics for the current method of density
determination with this function key. Note: You only need to
activate this function key if you have also activated the statistical
functions (Section 9.3.4). If the statistical system does not
contain any results, the key appears gray and cannot be
operated.
"CL Result":
You can clear the statistical data from the current method of
density determination with this function key, so that it is possible
to start a new series of measurements.
All the remaining function keys correspond to those for the "Weighing" application
(Section 6.2.2).

The "Density" application
80
9.4
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. The following explanations assume that the statistical function is not active
(notes on using the statistical functions may be found in Section 9.5).
9.4.1
Determining the density of non-porous solid bodies
To determine the density of non-porous solid bodies, the solid body is first weighed in air and then in the auxiliary liquid. The difference
in weights is the buoyancy, with the aid of which the software calculates the density.
In the application-specific settings, select "Solid" as the method (Section 9.3.2) and
specify the auxiliary liquid that will be used (Section 9.3.3).
Activate the appropriate function keys and information fields (Sections 9.3.6 and 9.3.7).
Note: The example shown here illustrates settings for determining the density of solid
bodies using distilled water as the auxiliary liquid. If an auxiliary liquid other than water
or ethanol is used, then instead of the "Temp. AL" key you should activate the
"Density AL" key.
If you are using water or ethanol as the auxiliary liquid, enter its temperature using
the "Temp. AL" function key. (Density tables for these two substances covering the
temperature range from 10°C up to 30°C are stored in the balance; see also
Sections 9.7 and 9.8.). The illustration here shows the corresponding input field (input
in °C with 1 decimal figure).
If you use 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 being used at the
current temperature (in g/cm3, max. 5 decimal places). This is necessary because
density tables are only saved for water and ethanol. The value you have entered appears
in the information field with the same name, which you should also activate. Note: The
"Temp. AL" function key, active in the example shown here, is not necessary for
determining density when using an auxiliary liquid other than water or ethanol. You
can, nevertheless, use it enter the current ambient temperature. This will in turn also be
included on the printout, and records the temperature at which the density was
determined.
Press the "Start" function key to start the density determination. The balance will
automatically carry out a taring, after which you will be prompted to put the solid body
in place (weighing in air).
If you are using the hanger (for weighing underneath the balance), hang the solid body
from the suspension equipment. If you are working with the optional density kit, follow
the instructions that are included with it.
The weight of the solid body appears in the lower left-hand corner of the window.
Press the "OK" key to accept the weight measurement.
The "Density" application
81
The result of the weighing is stored, after which you are prompted to immerse the solid
body in the auxiliary liquid.
If you are working with the hanger, place the container with the auxiliary liquid
underneath the suspension equipment. If you are working with the optional density kit,
follow the instructions that are included with it. In either case, ensure that the solid body
is submerged at least 1cm under the surface of the liquid, and that there are no air
bubbles in the container.
The weight of the solid body submerged in the liquid is displayed in the lower left-hand
corner of the window.
Press the "OK" key to accept the weight measurement.
The balance now determines the density of the solid body, and then displays the result
(the compensated and/or uncompensated value, depending on the settings that you
have made for output of the result, see Section 9.3.5).
If a printer is connected, the result of the density determination can be printed in
accordance with your specifications by pressing the "F" key (Section 9.3.8). The result
is retained until the next density determination has been completed, and can be printed
again if required. You will find a sample printout together with corresponding
explanations in Section 9.4.4.
9.4.2
Determining the density of liquids using a sinker
A sinker of known volume is often used to determine the density of liquids. The sinker must be weighed in the liquid whose density
is to be found. The difference in weights is the buoyancy, with the aid of which the software calculates the density.
In the application-specific settings, select the "Liquid" method (Section 9.3.2).
Activate the appropriate function keys and information fields (Sections 9.3.6 and 9.3.7).
The example shown here illustrates practical settings for determining the density of
liquids with the use of a sinker. Note: The "Temp. AL" key that is active in this example
is not necessary for this method of density determination. You can, nevertheless, use
it to enter the current ambient temperature. This will in turn also be included on the
printout, and indicates the temperature at which the density was determined.
Press the "Vol. Sinker" key, and enter the volume of the sinker (10.00000cm3 in this
example).
Press the "Start" function key to start the density determination. You are prompted to
attach the sinker (weighing in air).
If you are using the hanger for weighing underneath the balance, hang the sinker from
the suspension equipment. If you are working with the optional density kit, follow the
instructions that are included with it.
The weight of the sinker appears in the lower left-hand corner of the window.
Press the "OK" key to tare the sinker.
The "Density" application
82
After taring the sinker you are prompted to put the liquid whose density is to be
determined into a container. If you are working with the hanger (for weighing
underneath the balance), place the container with the liquid underneath the suspension
equipment. If you are working with the optional density kit, follow the instructions that
are included with it. In either case, ensure that the sinker is submerged at least 1cm
under the surface of the liquid, and that there are no air bubbles in the container.
The weight of displaced liquid is displayed in the lower left-hand corner of the window.
Press the "OK" key to accept the weight measurement.
The balance now determines the density of the liquid, and then displays the result (the
compensated and/or uncompensated value, depending on the settings that you have
made for output of the result, see Section 9.3.5).
If a printer is connected, the result of the density determination can be printed in
accordance with your specifications by pressing the "F" key (Section 9.3.8). The result
is retained until the next density determination has been completed, and can be printed
again if required.
9.4.3
Determining the density of pastes with the aid of a gamma sphere
A gamma sphere of known volume is usually used to determine the density of pastes. The paste is first tared without the gamma
sphere, and then weighed with the gamma sphere.
In the application-specific settings, select "Paste" as the method (Section 9.3.2).
Activate the appropriate function keys and information fields (Sections 9.3.6 and 9.3.7).
The example shown here illustrates practical settings for determining the density of
pastes through the use of a gamma sphere. Note: The "Temp. AL" key that is active in
this example is not necessary for this method of density determination. You can,
nevertheless, use it to enter the current ambient temperature. This will in turn also be
included on the printout, and indicates the temperature at which the density was
determined.
Press the "Vol. Gamma" function key and enter the volume of the gamma sphere
(10.00000cm3 in this example).
Press the "Start" function key to start the density determination. You will then be
prompted to place the sample on the pan (without the gamma sphere).
The weight of the sample appears in the lower left-hand corner of the window.
Press the "OK" key to tare the sample and to register the weight.
The "Density" application
83
When the sample has been tared, you will be prompted to submerge the gamma sphere
in the sample substance.
The weight of the substance displaced by the gamma sphere is displayed in the lower
left-hand corner of the window.
Press the "OK" key to accept the weight measurement.
The balance now determines the density of the paste, and then displays the result (the
compensated and/or uncompensated value, depending on the settings that you have
made for output of the result, see Section 9.3.5).
If a printer is connected, the result of the density determination can be printed in
accordance with your specifications by pressing the "F" key (Section 9.3.8). The result
is retained until the next density determination has been completed, and can be printed
again if required.
9.4.4
Sample printout of a density determination
If a printer is connected to the balance, the result will automatically be printed out when the density determination has been
successfully completed.
Note: The result is retained until the next density determination has been completed, and can be printed again if required by pressing
the "F" key. This may be necessary if you require a second copy of the printout, or if a paper shortage causes the printer to be unable
to complete the print successfully.

Using the density statistics
Statistics can be collected for each method of density determination. These store all the results that you have found whilst carrying
out the density determinations.
Default settings
In order to be able to use the statistics system, the statistic function (Section 9.3.4)
and both the "Result" and "CL Result" keys must be activated (Section 9.3.6).
Recording values for the statistics
When the statistic function is active, you will be asked at the end of each density
determination whether the result should be transferred to the statistics.
If you want to add the result of the current measurement to the statistics, press the "Yes"
key. The result will be incorporated into the statistics for the current method.
Transfer of the result is confirmed on the display.
If you do not want to include the result in the statistics, press "No". Although the result
will be retained until completion of the next measurement, it will not be added to the
statistics.
Displaying and printing the statistics
Make sure that the method of density determination whose statistics you want to display
or print is selected (Section 9.3.2).
Press the "Result" function key to call up the statistics. Note: If the statistical system
does not contain any values, the key appears gray and cannot be activated.
The information that you have selected for printing statistical data will appear in the
statistics window (Section 9.3.8). The factory setting is for the following values:
"n":
Number of samples
"x":
Mean density of all samples
"s":
Absolute standard deviation within a series of measurements
"Min":
Lowest density found within the series of measurements
"Max":
Highest density found within the series of measurements

10.1
Operating principle
You will find all the relevant information and updates for your balance on the METTLER TOLEDO website at the following address:
www.mt.com/balance-support
We recommend that you create a bookmark for this address in your web browser, so that you can access the site directly in future.
The balance software is loaded onto your computer along with the so-called “e-Loader II”. You can use this program to download
the software to the balance. The "e-Loader II" can also save the settings in your balance before the new software is downloaded
to it. You can reload the saved settings into the balance after the software downloading.
If the selected update includes an application that is not described in these instructions (or that has been updated in the meantime)
you can download the corresponding instructions in Adobe Acrobat® PDF format. You will need Adobe Acrobat Reader® to open PDF
documents (www.adobe.com).
The following Sections offer detailed information on obtaining software updates from the internet and downloading software into
the balance.
10.2
Requirements
The minimum requirements for obtaining applications from the internet and downloading them into your balance are as follows:
– PC with Microsoft Windows® operating system (Version 98, 98SE, ME, NT 4.0, 2000 or XP)
– Internet connection and web browser
– PC – balance connection cable (RS232 cable, 9-pin sub-D plug m/f, order number 11101051)

Loading the new software into the balance
Before you can load the software obtained from the internet into the balance, you must connect the balance through the RS232 cable
to the serial interface of your computer. Note: The cable must always be connected to the RS232C interface that is permanently
fitted at the factory!
Set the interface on the balance to the following values (detailed information on these system settings can be found in Section 5.6).
Select "Host" as the peripheral device, and then set the following communication parameters: baud rate: 9600, parity: 8 bits/none,
handshake: none, end of line: <CR><LF>, character set: ANSI/WIN.
Make sure that the corresponding communication parameters on your computer are set to the same values.
Start the "e-Loader II VXXX" installation program that you obtain from the internet ("XXX" is a place holder for the version number).
This program installs the e-Loader on your computer.
Follow the instructions, which will take you step-by-step through the installation.
The e-Loader II will start automatically after installation. This diagram illustrates the
starting screen for the e-Loader II.
You are asked to select the interface on the computer to which the balance is
connected (if necessary, this setting can be changed at any later time in the "Options"
–> "COM Port" menu).
Having selected the interface, click "Proceed".
A message window appears, reminding you that the standard RS232C interface on the
balance is to be used. The interface settings are also listed once again (see above).
Close the window by clicking on "OK".
Under the factory settings, the e-Loader II guides you through the updating process
using English as the language. If you wish, you can enter the "Options" –> "Language"
menu to select one of the other available languages. The e-Loader II will then display
all the instructions and notes in the language that you have chosen. The following
diagrams and information are based on the English version.
Before you update the software of your balance, please check in the "Help" menu that
the communication with the balance is functioning. (In the example shown here, the eLoader II is confirming that a balance is connected.)
If the e-Loader II reports that a balance is not connected, first check whether the correct
interface, with the right setting, has been selected, and then, if necessary, check that the
communication settings of the computer and the balance correspond.
Software updates
90
You can begin the updating process once you have made the necessary settings and
checked that the connection is operating. Click on "Start Software Update Procedure"
to do this. Follow the instructions provided by e-Loader II; these will guide you stepby-step through the updating process. e-Loader II will ask you whether you want to save
the current balance settings on your computer. We recommend that you carry out this
data backup. This will save you from having to enter all the settings again, since they
will all be returned to the factory settings in the course of the update. At the end of the
updating procedure, e-Loader II will ask whether the saved data should be reloaded
back into the balance.
Before you start the actual updating operation, you have the possibility to define a
Secure ID to protect the balance against unauthorized software updating operations.
To do this, click on the “Create Secure-ID” button. If you do not wish to use this function,
click on “Continue”.
The Secure ID is balance-specific and saved in the balance. Please make a note of the
Secure ID and keep it in a safe place. If you forget the Secure ID, no further updates can
be made to the balance.
Define the “Secure ID” and confirm it by entering it again in the field provided. Then click
on “Continue”.
The balance now displays a list of the updates which have been performed. In this
window you can enter a user identification “User ID” so that it is subsequently possible
to trace who performed the software updating operation.
Click on “Continue” to start the updating operation.
The balance software consists of a terminal software and a weighing-platform software.
After the terminal software has been loaded, updating of the weighing-platform software
begins. Here, too, you can define a Secure ID and enter a User ID.
Changing the Secure ID: The Secure ID can be changed when a new software updating
operation is started. To do so, click on the “Change Secure ID” field. You can now enter
a new Secure ID. If you leave the field empty, the Secure ID is deleted and no longer
active.
When the updating process has been completed, you can close e-Loader II. Your
balance will now operate with the newly loaded software.

Saving and reloading balance settings
As well as balance software updates, e-Loader II also offers a data backup function whereby the current balance settings can be copied
to a PC. This means that you have a backup copy of your settings available at all times. If necessary, you can copy this back into
the balance. The function can also be used to copy the settings from one balance to another.
In order to save the current balance settings on a PC, start e-Loader II and call up the
data backup function, as shown in the diagram here.
The dialog box opposite prompts you to select the path for saving the backup file
through the "Browse" button. e-Loader II suggests a combination of the current date and
the current time as a name for the backup file, and the file extension ".dat". (For
example: "2003_08_19_12_06.dat" for backup file that was created on the 12th
August 2003 at 12.06.) You are free to alter the file name, if you wish, but not the ".dat"
extension.
Click on "Start" to begin the data backup. Successful completion of the backup is
confirmed on the display.
To copy the balance settings from the PC back into the balance, select the reload
function, as illustrated here.
Having started the reload function you can select, via the "Browse" button, the settings
file that is to be loaded back into the balance, after which you can begin the transfer
process with "Start". Bear in mind that this will cause all the settings saved in the
balance to be overwritten!
Error messages

Error messages
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 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 or zeroing «G» (weight display flashes)
When the balance was switched on (connected to the power supply, switched on from
standby mode or by zero adjustment) 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
A taring or zeroing operation was aborted because a stable result was not obtained
during the stabilization time. Close the doors of the draft shield and check the working
location (drafts, vibrations). Press “OK” and repeat the taring/zeroing.
11.2
Further error messages
If any error messages appear (“Error x”) other than those described above, please contact your METTLER TOLEDO dealer.
Cleaning and service
93
12
Cleaning and service
Periodically clean the weighing pan, the drip tray, the housing, and the terminal of your balance using the brush supplied with it.
To clean the weighing chamber thoroughly, swivel the glasses of the draft shield away from the balance and
pull them out of their fastenings. Carefully raise the front of the weighing pan and lift it out of the guide. Pull
the drip tray away from the balance.
When you replace these parts, make sure they are in the correct position (see Section 2.2).
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.

MT-SICS Interface commands and functions
Many of the balances and scales used have to be capable of integration in a complex computer or data acquisition system.
To enable you to integrate balances in your system in a simple manner and utilize their capabilities to the full, most balance functions
are also available as appropriate commands via the data interface.
All new METTLER TOLEDO balances launched on the market support the standardized command set “METTLER TOLEDO Standard
Interface Command Set” (MT-SICS). The commands available depend on the functionality of the balance.
Basic information on data interchange with the balance
The balance receives commands from the system and acknowledges the command with an appropriate response.
Command formats
Commands sent to the balance comprise one or more characters of the ASCII character set. Here, the following must be noted:
• Enter commands only in uppercase.
• The possible parameters of the command must be separated from one another and from the command name by a space
(ASCII 32 dec., in this description represented as ).
/
• The possible input for “text” is a sequence of characters of the 8-bit ASCII character set from 32 dec to 255 dec.
• Each command must be closed by CRLF (ASCII 13 dec., 10 dec.).
The characters CRLF , which can be inputted using the Enter or Return key of most entry keypads, are not listed in this description,
but it is essential they be included for communication with the balance.
Example
S – Send stable weight value
Command
S
Response
S S WeightValue Unit
//
/
S I
/
S/S +
Send the current stable net weight value.
/
Current stable weight value in unit actually set under unit 1.
Command not executable (balance is currently executing another
command, e.g. taring, or timeout as stability was not reached).
Balance in overload range.
Balance in underload range.
Example
Command
S
Response
S S
Send a stable weight value.
/ /////100.00/g
The current, stable weight value is 100.00 g.

Command
@ – Reset
Command
SR – Send weight value on weight change (Send and Repeat)
Command
SR
Send the current stable weight value and then send continuously the stable
weight value after every weight change.
The weight change must be at least 12.5 % of the last stable weight value,
minimum = 30d.
ST – Send stable weight after pressing «F» key
Command
ST/
/1
Send the current stable net weight value each time when F is pressed.

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
