1 Getting to know your balance
Thank you for choosing a METTLER TOLEDO balance.
1.1 Introducing the SB precision balances
4
The SB family of precision balances comprises a range of precision balances which differ from each other in
relation to their weighing range and resolution.
• Range of weighing 8.1 kg to 32.1 kg.
• Readability of 0.1 g to 1 g
In addition to basic weighing operations such as weighing, taring and adjusting (calibration), the following
functions can be activated (section 5):
• Piece counting
• Percent weighing
• Dynamic weighing for unstable weighing samples.
SB balances can be optimally matched to the ambient conditions through appropriate setting of the vibration
adapter (section 4.2.3).
METTLER TOLEDO DeltaRange balances also have a movable fine range with 10 times smaller display increments (section 3.4).
All SB balances are fitted with an RS232C interface as standard (section 6.2).
Note
• Certified versions of the SB balances are also available, please ask your METTLER TOLEDO dealer for details.
1.2 Cautionary notes
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.
It is not permitted to use the balance in hazardous environments.
Use only the AC adapter delivered with your balance, and check that the voltage printed on it is the same as your
local power supply voltage. If it does not, contact your local dealer.
• Use only with a tested AC adapter with SELV output current.
• SB balances may only be used indoors in a dry environment.
• 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, contact your METTLER TOLEDO dealer.
• Use only balance accessories and peripheral devices from METTLER TOLEDO; they are optimally adapted to your
balance.

1.4 The keys of the SB balances (overview)
SB balances have two operator control levels: the weighing mode and the menu. The keys have different
meanings, depending on the operator control level and how long a key is pressed.

2.1 Unpacking / standard equipment
All SB balances are supplied in an environmentally harmless package. The standard equipment of the SB balances includes:
• AC adapter, to national codes,
• Weighing pan
• Protective cover, mounted
• Operating instructions, to allow optimum utilization of the capabilities of your balance,
• EC declaration of conformity
2.2 Setting up
The optimum location
The correct location makes an important contribution to the accuracy of the weighing results of precision balances.
Hence, ensure a
• stable, vibration-free position as horizontal as possible.
• the surface must be able to safely carry the weight of a fully loaded balance.
Avoid
• direct sunlight,
• excessive temperature fluctuations,
• powerful drafts (e.g. from fans or air conditioners)
Note
If vibrations can not be prevented, the balance can still provide accurate results if the vibration
adapter is set accordingly, see section 4.2.3.
Leveling
To assure repeatable weighing results at all times, the balance must be exactly horizontal. To compensate
minor unevenness at its location, the balance can be leveled:
➞ Turn the leveling feet of the balance housing until the air bubble is in the center of the level control.
Note
The balance must be releveled each time its location is changed.
Connecting to the power supply
➞ Before connection of the AC adapter, check that the imprinted voltage value matches the local supply
voltage. If this is not the case, please contact your local METTLER TOLEDO dealer.
➞ Plug AC adapter into AC adapter socket of the balance and connect to the power supply.
The balance performs a self-test. The test is finished when “OFF” appears.
On
➞ Press
briefly: balance is in operational readiness. Before any work is performed with the bal-
ance, it must be adjusted (calibrated), (section 2.3).
Note
The PP-B10 PowerPack (rechargeable, external battery) can be used to operate all B balances
independently of the power supply (section 6.3).
