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.

2.2Cautionary 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.

2.3Setting 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

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 vibration adapter can be used to match your balance to the ambient conditions (vibrations, drafts at
location). If you work in surroundings which are practically free from temperature fluctuations, drafts, and
vibrations, select “StabLE”. On the other hand, if you work in surroundings where the conditions are constantly
changing, select “unStAbLE”. For normal ambient conditions, select “UnivErS” (Standard). This is the factory
setting.
4.3.6Measurement release (Repeatability) (6th menu option) (Only on AB135-S/AB265-S models)
You can use this setting to specify how rapidly the balance considers the measurement value to be stable and
releases it. The “FASt” setting is recommended if you require rapid results and their repeatability is of secondary
importance. The “rELiAbLE” setting gives very good repeatibility of the measurement results, but lengthens the
stabilization time. When the balance is set to “FASt -rELiAbLE” (fast and reliable), the weight display is quickly
released as stable, and gives good repeatability. This is the factory setting.

5.3Dynamic weighing
Dynamic weighing is suitable for the weighing of unstable weighing samples. The mean value of the weighing
results is determined over a specified time period (weighing time). The more unstable the weighing sample,
the longer the selected weighing time.
Requirement
“F dYn A” for automatic start or “F dYn M” for manual start must be activated in the menu (Section 4).
Factory setting is a weighing time of 3 seconds (t = 3").

You will find a detailed description of the available interface
commands in the brochure “Reference Manual MT-SICS Basic-
S balances 11780447” available from your METTLER TOLEDO
dealer or download from the Internet (www.mt.com/AB-S).
The wide range of features of the B-S balances regarding documentation of the results can
not be exploited to the full until a printer, e.g. the GA42 or LC-P45 from METTLER TOLEDO
is attached. The printed results make a decisive contribution to a simple way of working in
compliance with GLP/GMP.
6.3MT-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.
Example
S – Send stable weight value
CommandSSend the current stable net weight value.
ResponseS
//
/S
/WeightValue
//
//
//
/Unit
//
//
Current stable weight value in unit actually set
under unit 1.
//
S
/ICommand not executable (balance is currently
//
executing another command, e.g. taring, or
timeout as stability was not reached).
//
S
/+Balance in overload range.
//
//
S
/-Balance in underload range.
//
Example
CommandSSend a stable weight value.
//
ResponseS
//////////
/S
/////100.00
//
//////////
//
/g
//
The current, stable weight value is 100.00 g.
• 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.

SI – Send value immediately
CommandSISend the current net weight value, irrespective of
balance stability.
SIR – Send weight value immediately and repeat
CommandSIRSend the net weight values repeatedly,
irrespective of balance stability.
Z – Zero
CommandZZero the balance.
ST – Send stable weight after pressing ± (transfer) key
CommandSTInquiry of actual status of the ST function.
SU – Send stable weight value with currently displayed unit
CommandSUAs the “S” command, but with the currently
displayed unit.
@ – Reset
Command@Resets the balance to the condition found after
switching on, but without a zero setting being
performed.
SR – Send weight value on weight change (Send and Repeat)
CommandSRSend 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.
Regular servicing of your balance by a service technician prolongs its working
life. Ask your METTLER TOLEDO dealer for details of servicing options.
Cleaning
The balance housing and weighing pan are made of high-grade durable
materials. All commonly used cleaning agents can therefore be used.
Soiled protective covers can be replaced on all balance types (see Optional
equipment).
Note
After working with chemicals, it is advisable to wash or clean the weighing pan
and the bottom plate (if draft shield fitted).
Although all materials are of high quality, corrosion may occur if corrosive
substances are deposited on chrome steel for an extended period of time (and if
air is excluded, for example by a coating of grease).
Attention
If you have to dispose of the instrument, contact your METTLER TOLEDO dealer.
