This symbol indicates press and hold key down (longer than 1.5 s).
This symbol indicates a flashing display.
This symbol indicates an automatic sequence.
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.
5Introduction
2Safety Information
Always operate and use your balance only in accordance with the instructions contained in this manu
al. The instructions for setting up your new balance must be strictly observed.
If the balance is not used according to these Operating Instructions, protection of the balance may
be impaired and METTLER TOLEDO assumes no liability.
It is not permitted to use the balance in explosive atmosphere of gases, steam, fog,
dust and flammable dust (hazardous environments).
For use only in dry interior rooms.
Do not use sharply pointed objects to operate the keyboard of your balance! Although
your balance is very ruggedly constructed, it is nevertheless a precision instrument.
Treat it with corresponding care.
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, con
tact your METTLER TOLEDO dealer.
Use only balance accessories and peripheral devices from METTLER TOLEDO; they are
optimally adapted to your balance.
Use only the original universal AC adapter delivered with your balance.

4.1Scope of delivery
1 Open the packaging and carefully remove all components.
2 Check the delivered items.
The standard scope of delivery contains the following items:
●
Balance
●
Weighing pan and weighing pan support
●
Protective cover for load cell cone (mounted)
●
Protective cover (mounted)
●
Stackable cover
●
Universal AC/DC adapter (country specific)
●
Operating instructions printed or on CD-Rom depending on the country.
●
Quick Guide (English) depending on the country.
●
EC declaration of conformity
4.2Selecting a location
The correct location makes an important contribution to the accuracy of the weighing results of preci
sion balances. Select a stable, vibration-free position that is as horizontal as possible. The surface
must be able to safely carry the weight of a fully loaded balance.
Observe ambient conditions see Technical Data (page59).
Avoid the following:
●
Vibrations
●
Excessive temperature fluctuations
●
Direct sunlight
●
Powerful drafts (e.g. from fans or air conditioners)
4.3Leveling the balace
The balances have a level indicator and two or four adjustable
leveling feet to compensate for slight irregularities in the surface
of the weighing bench. The balance is exactly horizontal when
the air bubble is in the middle of the level glass.
Align the balance horizontally by turning the leveling feet of the
balance housing until the air bubble is in the inner circle of the
level indicator.
Note: The balance should be leveled and adjusted each time it is
moved to a new location.
13Installation and Putting Into Operation
4.4Installing the components
1 Remove the protective cover for weighing
cone (1). Keep it for later use.
2 Place the following components on the bal
ance in the specified order:
• Pan support (2)
• Weighing pan (3)

4.5Installation of the protective cover
Install the protective cover according to the illustration on the
right, using a screwdriver.
14 Installation and Putting Into Operation
4.6Using the stackable cover
The stackable cover can be placed on the balance. It protects the balance from dust when it is not
used and allows you to stack up a maximal number of 5 balances.
4.7Power supply
4.7.1AC operation
Your balance is supplied with an country-specific AC/DC adapter. The power supply is suitable for all
line voltages in the range: 100 - 240 VAC, 50/60 Hz (for detailed specifications, see section "techni
cal data").
First, check the local line voltage is in the range 100 - 240 VAC, 50/60 Hz and
whether the power plug fits your local power supply connection. If this is not the
case, on no account connect the balance or the AC adapter to the power supply,
but contact the responsible METTLER TOLEDO dealer.
Important:
●
Before operating, check all cables for damage.
●
Guide the cables so that they cannot become damaged or interfere with the
weighing process!
●
Take care that the AC adapter cannot come into contact with liquids!
●
The power plug must be always accessible.
Connect the AC adapter to the connection socket on the back of
your balance (see figure) and to the power line.
4.7.2Battery operation
The Balance can also operate with batteries. Under normal operation conditions, the balance works
independently of the AC power line for about 8 to 15 hours (using alkaline batteries). Immediately
after the AC power supply is interrupted e.g. by withdrawing the power plug or if there is a power fail
15Installation and Putting Into Operation
ure, the balance switches automatically to battery operation. Once the AC power supply is restored, the
balance reverts automatically to AC operation.
Note: It is also possible to use rechargeable batteries. Charging batteries inside the balance is not
possible.
battery full
2/3 full
1/3 full
battery empty
When the balance is operating on its batteries, the battery symbol
in the display lights up. The number of segments that are lit is an
indicator of battery condition (3 = fully charged, 0 = discharged).
When the batteries are almost completely discharged, the battery
symbol flashes.
Inserting / Replacing Batteries
The balance must be disconnected from the power supply when carrying out all setup
and mounting work.
●
Make sure that the balance is off before removing or inserting batteries.
●
Never put the balance on the weighing cone without mounted cone protection.
The load cell could be damaged.
●
Battery Warnings: Read and follow all warnings and instructions supplied by the
battery manufacturer.
●
Do not mix different types or brands of batteries. Performance of batteries can
vary very greatly depending on the manufacturer.
●
If you don't operate the balance with batteries for an extended period, it is recom
mended to remove the batteries from the balance.
●
Batteries must be disposed of in an environmentally responsible manner. No
attempt must be made to incinerate or disassemble item.
Your balance uses 4 standard AA (LR6) batteries (alkaline batteries preferred)
16 Installation and Putting Into Operation
1 Remove weighing pan and pan support.
2 Turn the balance carefully on its side.
3 Open and remove the battery-chamber cover.
4 Insert / replace the batteries with the correct
polarity as shown in the battery holder.
5 Insert and close the battery-chamber cover.
6 Turn the balance carefully to its normal posi
tion.
7 Reinstall all components in the reverse order.

4.8General requirements
4.8.1Switching on the Balance
Before working with the balance, it must be warmed up in order to obtain accurate weighing results.
To reach operating temperature, the balance must be acclimatized and connected to the power supply
for at least 30 minutes.
4.8.2Adjusting the Balance
To obtain accurate weighing results, the balance must be adjusted to match the gravitational accelera
tion at its location and depending on the ambient conditions. After reaching the operation temperature,
adjusting is necessary
●
before the balance is used for the first time.
●
after a change of the location.
●
at regular intervals during weighing service.
4.9Adjustment
4.9.1Adjustment with external weight
Note:
Approved models must be adjusted at the place of operation. Before putting in operation, and depend
ing on particular country certification legislation, the balance will then have to be checked and sealed
by authorized personnel. See the detailed information delivered with this instrument.
