1 Setting up the scale
Please read these operating instructions carefully and follow them exactly! If you find that any items are missing or incorrect, or if
you have any other problems with your scale, please contact your authorized METTLER TOLEDO representative.
1.1 Important
Various different models of the ITB scale terminal are available. Only the benchtop model is described in these instructions.
If you ordered a wall- or stand-mount terminal, please refer to the installation instructions delivered separately. The AccuPac
(special equipment) can contain a number of options, such as additional interfaces or a storage battery. If you ordered an
AccuPac it will have been configured at the factory with the options you requested and fastened below the terminal. The installation
of an AccuPac after delivery is possible, but it is very costly.
1.2 Unpacking and checking the delivered items
Remove the scale and accessories from the packaging and check the delivered items:
Terminal and weighing plaform with installed weighing pan and level indicator (certified scales only)
Open-end wrench for leveling the weighing platform
Operating instructions (this document)
Special accessories (if any) as per packing list
1.3 Safety and environment
For safe and environmentally harmless operation of your scale, observe the following instructions:
Do not use the scale in hazardous environments (unless it is specially marked).
Although the ITB scale is protected to IP65, it must not be used in environments where
there is a corrosion hazard. Never flood the scale or immerse it in liquids!
If the power supply cable is damaged, the scale must not be used. Check the cable
regularly.
Do not open the weighing platform or terminal since this will void the guarantee. Do
not use rigid objects to clean inside the weighing platform.
Treat the scale with care, it is a precision instrument. Avoid knocking the weighing pan
or placing excessively heavy loads on it.
If the ITB scale will be used in food processing areas: Those parts of the scale
which may come into contact with food have a smooth surface and are easy to clean.
The materials used do not shatter and contain no harmful substances. In food
processing areas, it is advisable to use the protective cover (accessory). This must
be regularly cleaned like the scale itself. A damaged or heavily soiled protective cover
must be replaced immediately.
When disposing of the scale, observe the applicable environmental regulations. If the
scale is fitted with a storage battery, note that the battery contains heavy metals and
must therfore not be disposed of as normal waste! Observe local regulations for disposal
of environmentally harmful substances.
IP 65
Chapter 1: Setting up the scale

1.4 Selecting a location and leveling the scale
The proper location can influence the accuracy of the weighing results!
Choose a stable, vibration-free flat surface. The surface must be able to bear the
weight of the fully loaded scale safely.
Pay attention to environmental conditions:
No direct sunlight
No strong drafts (e.g. from fans or air conditioning)
No excessive temperature fluctuations
Adjust the scale horizontally by turning the leveling feet, then use the open-end wrench
supplied to tighten the locknuts of all the leveling feet so as to prevent unintentional
movement.
On certified scales, the weighing platform has a level indicator. The air bubble must lie
within the inner circle of the indicator.
Note: The level indicator can be mounted in a different position. Undo the two fastening
screws and move the level indicator to one of the positions provided (drilled holes in
the weighing platform).
Major changes of geographical location
Each scale is adjusted by the manufacturer for the local gravitational conditions (geo
value). If there is a major change of geographical location, this adjustment must be
corrected by a service technician (see chapter 3.4.1). Certified scales must also be
recertified in accordance with local national regulations for certification.
=000Ð
Before connecting the power supply, check that the voltage printed on the back of
the scale is the same as the local power supply. If it is not, do not connect the scale,
and contact your authorized representative.
If the voltage is correct, connect the plug on the power cable to the power supply.
After the scale has been connected, it performs a display test. When the display shows
zero, the scale is ready for operation. For maximum precision, after installing the scale
carry out an adjustment/calibration (Chapter 3.4.1). Important: Certified scales must
be adjusted by an authorized laboratory. Ask your authorized representative.
Scales which have an AccuPac with built-in storage battery can operate under
normal conditions for approx. 30 hours disconnected from the power supply (with
backlighting turned off and no accessories connected). As soon as the power supply
is interrupted, the scale automatically switches over to battery operation. When power
is restored, the scale automatically switches back to power supply operation. The
battery symbol indicates the current charge status of the storage battery (1 segment =
approx. 25% capacity). If the symbol flashes, the storage battery must be recharged
(8 hours minimum). If work continues while recharging, it takes longer. The storage
battery is protected against ovecharging, so the scale can be permanently connected
to the power supply without problem.

The metrology features of the balance and any possible available adjusting weight must be checked at regular intervals
within the scope of quality assurance. For this purpose, the answerable user must define a suitable interval as well as
the nature and scope of this check. Information is available on KERNs home page (www.kern-sohn.com) with regard to
the monitoring of balance test substances and the test weights required for this. Test weights and balances can be
adjusted quickly and at a reasonable price in KERNs accredited DKD calibration laboratory (return to national normal).
General:
According to the EU guideline 90/384/EEC balances must be verified officially if they are to be used as follows (legally
regulated area):
a) For commercial transactions if the price of goods is determined by weighing
b) For the production of medines in pharmacies as well as for analyses in the medical and pharmaceutical
laboratory
c) For official purposes
d) For the production of finished packages
In case of doubt, please contact your local office of weights and measures.
Verification information
An EU qualification approval is available for those balances marked as appropriate for verification in the technical data.
In the event that the balance is applied in an area subject to verification as described above, it must be officially verified
and re-verified at regular intervals.
Re-verification of a balance is carried out in compliance with the respective legal provisions of the states. The term of
verification validity for balances in Germany, for example, is normally 2 years.
The legal provisions of the country of use are to be observed.

2 Weighing
This chapter explains how you switch the scale on and off, adjust the zero setting, tare the scale, carry out weighings, and record
weighing results.
2.1 Switching on/off and setting to zero
You switch the scale on and off by pressing the key.
After it has been switched on, the scale carries out a display test. When the weight
display appears, the scale is ready for weighing and is automatically set to zero.
Note: The key can be used to set the scale to zero at any time.
2.2 Simple weighing
Place the weighing sample on the pan.
Wait until the stability detector (small ring at left-hand edge of display) goes off and then
read the weighing result.
You can use the key to transmit the weighing result via the interface to a
peripheral device (printer, computer) (see Chapter 4.3 for sample report).
(65Ð
2.3 Weighing with tare
Place the empty weighing container or the packaging material on the weighing pan
and press the key to tare the scale.
The zero display and the NET (net weight) symbol appear. Note: If the automatic
tare function is active (Chapter 3.4.3), you need not press the key, since the first
weight added is taken to be the tare (T flashes in the display until the tare is added).
Chapter 2: Weighing

Place the weighing sample on the weighing pan and ...
... read the result (net weight of the weighing sample).
Note: The tare weight is retained until either a new tare is determined, or the scale is set
to zero or switched off.
If the automatic taring function is active, the tare is automatically cleared when weighing
is completed and the weighing pan emptied; the scale is then ready for the next taring
and weighing.

2.4 Dynamic weighing
For unstable weighing objects (e.g. animals) the dynamic weighing function with
automatic or manual start can be activated (section 3.5.1). If the dynamic weighing
function is active, the mouse symbol appears at the bottom edge of the display.
With dynamic weighing the scale measures 56 weighing values in 4 seconds and
calculates their mean value.
With dynamic weighing and automatic start the measurement begins automatically as
soon as there is a change in weight.
With dynamic weighing and manual start the measurement is started by touching
the key.
During dynamic weighing, horizontal segments appear in the display, after which the
calculated mean value is displayed. The star symbol at the left-hand edge indicates that
the result is a calculated one. To start a new weighing cycle, the scale must be unloaded.
Note: Only activate the dynamic weighing function to weigh unstable goods. In normal
operation the standard weighing function yields more accurate results more rapidly.

3The menu
The menu can be used to change the settings for the scale and to activate functions, thereby allowing the scale to be adapted to
individual weighing neeeds.
Important: To avoid incorrect operation of the scale in normal use, the menu can be protected with a password. The scale
differentiates between a user and a supervisor. When the scale leaves the factory, the entire menu can be accessed by both user
and supervisor. We therefore recommend you to define your own supervisor password as soon as you set up the scale
(Chapter 3.6.2). This limits access by the user to a small number of menu items (calibration, and settings for energy-saving
mode and backlighting).
3.1 Overview and operation
Chapter 3.3 contains a complete overview of the menu and all the possible settings.
3.2 Calling up the menu and entering the password
COdE
Press the key and hold it down until the prompt to enter the password appears.
User: No password required, just press the key.
Supervisor: Enter password (sequence of keystrokes) immediately and confirm with
the key, otherwise after a few seconds the scale returns to weighing mode. If an
incorrect password is entered, the menu cannot be called up.
Note: When the scale leaves the factory no supervisor password is defined, so when
the password is requested, just press the key.
If the password entered is correct, the first block of the menu appears (SCALE).
