PB-S (0.01g/ 0.1 g/1 g)
Several types of construction – uniform operation
• The B-S balance line ranges from high-resolution analytical balances (AB-S) with a readability of 0.1 mg /
0.01 mg through to precision balances (PB-S) with a readability of 0.001 g to 1 g. The weighing ranges
extend from 51 g to 8.1 kg.
• The operation of all theses balances is identical.
Balance features
• In addition to basic weighing operations such as weighing, taring and adjusting (calibration) the functions
“Piece counting”, “Percent weighing” or “Dynamic weighing” (automatic or manual start) can be
activated.
• METTLER TOLEDO DualRange balances have two ranges. These models also have a fine (semimicro)
range from 0 to 31 g respectively 61 g. In this fine range the balance shows the result with a higher
resolution, i.e. with one decimal place more.
• METTLER TOLEDO DeltaRange balances also have a movable fine range, with 10 times smaller display
increments, over the the entire weighing range.
• Several B-S balances are fitted with a glass draft shield in the factory; with other models a draft shield is
available as an optional extra.
• All balances in the B-S range are fitted with an RS232C interface as standard.
• AB-S models and certified balances have an internal adjustment weight.

All B-S balances are available as certified versions. Please ask your METTLER TOLEDO dealer for details.

2.1 Unpacking / standard equipment
All B-S balances are supplied in environmentally compatible packaging. The standard equipment for every
balance comprises:
• AC adapter, to national codes
• AC adapter with country-specific power cable (Models AB135-S / AB265-S)
• Weighing pan with pan support or draft shield element
• Transparent plastic protective cover, fitted, to keep your balance clean at all times
• Retaining ring for protective cover, fitted, only on balances without draft shield
• Draft shield with fitting instructions, standard supply for models AB-S and PBxx3-S (for other models a
draft shield is available as an optional extra)
• Operating instructions, to ensure optimum utilization of your balance's capabilities
• CE declaration of conformity (in separate brochure 11780294)

2.2 Cautionary notes
• B-S balances must not be operated in hazardous areas with the standard-supply AC adapter.
• Before connecting the AC adapter, verify that the voltage printed on it corresponds to the local mains voltage.
If this is not the case, please contact your local METTLER TOLEDO dealer.
• B-S balances may only be used indoors in a dry environment.

2.3 Setting up, leveling, preparations for weighing below the balance, connecting to power supply
The optimum location
The correct location makes an important contribution to the accuracy of the weighing results of high-resolution
analytical and precision balances.
Hence, ensure a
• stable, vibration-free position as horizontal as possible
Avoid
• direct sunlight
• excessive temperature fluctuations
• drafts
The best location is on a stable bench in a corner protected against drafts, as far away as possible from doors,
windows, radiators or the louvers of air conditioners.
Antitheft device
B-S balances are equipped with a lug for the optional antitheft device.
The antitheft device (cable with lock) is suitable for all models. It is available from METTLER TOLEDO unter the
order number 590101.
Leveling
B-S balances have a spirit level and two 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.
Procedure
Adjust the two leveling feet appropriately until the air bubble comes to rest exactly in the middle of the glass:
Air bubble at “12 o'clock” turn both feet counterclockwise
Air bubble at “3 o'clock” turn left foot clockwise, right foot counterclockwise
Air bubble at “6 o'clock” turn both feet clockwise
Air bubble at “9 o'clock” turn left foot counterclockwise, right foot clockwise
Note
The balance should be leveled and adjusted (Section 2.4) each time it is moved to a new location.
Preparations for weighing below the balance
To carry out weighing operations below the balance, the special cover on the underside of the balance must be
slackened (care: when doing this the balance may only be laid on its side, not turned upside down!), turned
through 180° and retightened. This exposes the opening for the hanger, making weighing below the balance
possible.
Connecting the power supply
➞ Before connecting the AC adapter, check that the voltage printed on it corresponds to the local mains
voltage. If this is not the case, please contact your local METTLER TOLEDO dealer.
➞ Plug the AC adapter into the AC adapter socket on the balance, and connect to the power supply.
➞ The balance performs a self-test. This test is finished when “OFF” appears.
➞ Press the «On» key briefly: the balance is in operational readiness. Before any work is performed with the
balance, it must be adjusted (Section 2.4).
Notes
To achieve accurate results with analytical balances (AB-S), these must be connected to the power supply for
at least 60 minutes to warm up to operating temperature before the first weighing operation is carried out.
An optional AccuPac B-S (rechargeable external battery) can be used to operate all B-S balances independently of the mains power supply

To obtain accurate weighing results, the balance must be adjusted to match the gravitational acceleration at its
location.
Adjusting is necessary
• before the balance is used for the first time
• at regular intervals during weighing service
• after a change of location
Procedure
To obtain accurate results, the balance must be connected to the power supply for 30 minutes (AB-S analytical
balances 60 minutes) in order to reach operating temperature before adjusting.
Analytical balances (AB-S), Precision balances (PB-S certified)
Adjusting with internal weight
➞ To carry out this operation, in the second menu option (Adjustment) select “CAL int” (=factory setting)
(Section 4.1).
➞ Unload weighing pan
➞ Press and hold the «Cal/Menu» key down until “CAL” appears in the display, then release key.
➞ The balance adjusts itself automatically.
The adjusting is finished when the message “CAL done” appears briefly in the display, followed by
“0.0000 g”. The balance is again in weighing mode and ready for operation.

AB-S and PB-S certified models
All AB-S and PB-S certified models have an internal adjustment weight and adjust themselves automatically:
AB-S: 2 times within 2 hours of connection to the power supply, thereafter periodically.
PB-S: On connection to the power supply, thereafter periodically.
For the certified AB-S and PB-S models, manual adjustment with the internal weight can also be done at a
keystroke. To obtain best possible results, it is advisable to adjust these balances regularly (for procedure, see
Adjustment Using Internal Weight).

The certified AB-S models can also be adjusted with an external weight (for procedure, see Adjustment Using
External Weight).
Because of certification legislation, the certified PB-S models cannot be adjusted with an external weight.
Notes
The adjustment procedure can be terminated at any time with the «C» key. The message “Abort” appears briefly
to confirm that adjustment has been canceled, and the balance reverts to weighing mode.
