1 Setting up the scale
Please read through these operating instructions carefully and adhere to them at all times. If you discover that materials are
missing or that the wrong ones have been supplied, or if you have any other problems with your scale, please refer to the
dealer and salesperson concerned, or if necessary to the METTLER TOLEDO representative responsible.
1.1 Safety and environment
Do not use BBA462 / BBK462 in hazardous areas!
Our product range includes special devices for hazardous areas.
If the power cord is damaged, the scale must no longer be operated.
Therefore check the cable regularly and ensure that a free space of about 3
cm is left at the rear of the scale, so that the cable is not kinked too severely.
DANGER!
Electric shock hazard!
Always pull out the mains plug before any work on the device.
DANGER!
Electric shock hazard if the mains cable is damaged!
Check the mains cable for damage regularly and replace it immediately if
it is damaged.
On the rear side of the device, maintain a clearance of at least 3 cm in
order to prevent the mains cable bending too much.
CAUTION!
On no account open the device!
The warranty is void if this stipulation is ignored. The device may only be
opened by authorized persons.
Call METTLER TOLEDO Service.
CAUTION!
Handle the compact scale with care.
The scale is a precision instrument.
When the weighing pan has been removed, never clean the area under
the load plate holder with a solid object!
Do not put excessive loads on the scale.
Avoid banging the weighing pan.
Parts of the scale coming into contact with foodstuffs have smooth surfaces
and are easy to clean. The materials used do not splinter and are free of
harmful substances.
With foodstuffs, it is recommended to use the supplied protective cover.
- Clean the protective cover regularly and carefully.
- Replace damaged or very dirty protective cover immediately.

In conformance with the European Directive 2002/96 EC on Waste Electrical
and Electronic Equipment (WEEE) this device may not be disposed of with
domestic waste. This also applies to countries outside the EU, per their
specific requirements.
➜ Please dispose of this product in accordance with local regulations at the
collecting point specified for electrical and electronic equipment.
If you have any questions, please contact the responsible authority or the
distributor from which you purchased this device.
Should this device be passed on to other parties (for private or professional
use), the content of this regulation must also be related.
Thank you for your contribution to environmental protection.
If the device is equipped with a storage battery: The nickel metal hydride
(NiMH) storage battery does not contain any heavy metals. However, it may
not be disposed of with the normal refuse.
➜ Observe the local regulations on the disposal of materials that are
hazardous to the environment.
1.2 Positioning and leveling the scale
The correct location is a decisive factor in ensuring accurate weighing results.
- Choose a stable and vibration-free location (particularly important for high-
resolution scales using Mettler Toledo MonoBloc technology). Place the scale on
a surface that is as horizontal as possible and strong enough to bear its weight
when fully loaded.
- Check the ambient conditions.
- Avoid:
- direct sunlight
- strong drafts (e.g. from fans or air conditioning systems)
- excessive temperature fluctuations.
Turn the adjustable feet so that the scale is horizontal. If a spirit level is filled, the
bubble must be located within the inner circle.
Note: The BBA462 / BBK462 has a special filter that accelerates certain procedures
(zeroing, taring, determining the reference weight for piece counting) in a nontranquil environment. This inevitably means that there is a slight loss of accuracy
with the results. For high-precision results, care must be taken to ensure as tranquil
and stable an environment as possible, so that the filter is not activated.
METTLER TOLEDO BBA462 / BBK462 Chapter 1: Setting up the scale
11
Major changes in geographical location:
The manufacturer adjusts each scale to the local gravity conditions (GEO value). In
the event of major geographical location changes, this setting must be adjusted by a
service technician. Certified scales must also be recertified observing the national
certification regulations. These steps are not necessary for scales with an internal
calibration weight.
1.3 Connecting to power supply
Before connecting the power supply plug or AC adapter (AccuPac version), verify that
the voltage stated on the model plate is the same as the local power line voltage.
Connect the power cord plug or the AC adapter plug to the supply, then connect the
AC adapter (AccuPac version) via the jack at the rear of the scale.
Powering up the scale initiates a display test in which all the segments and then the
software version are briefly displayed. Once the decimal zero appears in the display,
the scale is ready to operate.
For maximum possible precision, adjust/calibrate the scale after installing it (Chapter
5.4.1). Note: Certified scales must be adjusted by an authorized organization.
Please consult your dealer.
1.4 Battery operation
Scales with a built-in battery can work independently from the mains for
approximately 30 hours in normal operation. A prerequisite for this is that the
background lighting is switched off and that no peripheral devices are connected.
The device automatically switches to battery operation as soon as the mains supply
is interrupted. When the mains supply is restored, the device automatically switches
back to mains operation.
The battery symbol indicates the present charging level of the battery. 1 segment
corresponds to approx. 25 % capacity. When the symbol flashes the battery must be
charged (min. 4 hours). The charging period is extended if work is continued during
charging. The battery is protected against overcharging.
The charging time of the storage battery amounts to approx. 6 hours. If the device
continues to be operated during the charging process, the charging time is extended.
The storage battery has a service life of approx. 1,000 charging/discharging cycles.
The storage battery is also suitable for permanent mains operation.
➜ In order to obtain the full nominal capacity we recommend that you discharge the
storage battery at regular intervals (approx. every 4 weeks) through normal
operation.

METTLER TOLEDO BBA462 / BBK462 Chapter 2: Basic functions
15
The bar graph at the top of the display shows how much of the weighing range is
being used and how much is still available (as % of total scale capacity).
Wait until the stability detector (a small ring at the left edge of the display)
disappears, then…
… read the indicated net weight and press the «HighRes» key.
The «HighRes» key enables the weighing result to be displayed in control mode, i.e.
with a higher resolution.
Note: Each of the highest possible resolutions will be displayed in DMS scales. In
MonoBloc scales, the resolution will be ten times higher. Control mode is not
available if the maximum resolution has already been selected in Vision setup
(Chapter 5).
Press «Average» key to perform average weighing or press «Cancel» key to go back
to the normal weighing mode. The averaged value corresponds with the average
weight and the procedure takes about 20 seconds.
2.5 Weighing with tare
The tare can be specified by placing the weighing container on the scale or by entering the tare weight numerically. The two
possibilities are described below. Moreover, the gross and net weights can be determined separately.
2.5.1 Taring by placing the weighing container on the scale
Place the empty weighing container or packaging on the scale.
Press the «ÆTÅ»
key briefly to tare the scale.
Chapter 2: Basic functions METTLER TOLEDO BBA462 / BBK462
16
The zero display and the “Net” (net weight) symbol appear. Note: If the automatic
tare function has been activated in Vision Setup (Chapter 5.4.3), there is no need to
press the «ÆTÅ»
key. Prerequisite: The packaging material must be heavier than 9
display steps of the scale.
Place the material to be weighed in the container, then…
… 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.
2.5.2 Entering the tare weight numerically (pre-tare)
Note: The «PT» softkey is not given as a standard softkey, because pre-tare can also
be inputted using the Short Input Mode (see Chapter 3.1). This function key must
thus be defined separately in Vision Setup. To define function keys, see Chapter
5.5.7. You will find an overview of all function keys that can be defined in Chapter
5.3.2. Press «
» to show other available function keys and press « » to go
back to the first page of the function keys.
Press the «PT» softkey.
… appears on the screen.
Press the «New» softkey to enter the tare weight. If you want to work further with other
tare weights, you can set and define the «Add. Tare» key. The additional tare weights
will be added to the actual tare weights. The «Undo» softkey deletes the last defined
"Add. Tare Weight". The «Delete» softkey deletes the whole tare weight.
.
1 5
Press the «New» softkey now and using the numeric keypad, enter the known tare
weight in the current weighing unit and confirm with «OK».
The tare values entered appear in the display with a negative sign and the symbol
“Net” (net weight). As soon as the weighing container with the corresponding weight
is placed on the scale, the zero display appears.
METTLER TOLEDO BBA462 / BBK462 Chapter 2: Basic functions
17
2.5.3 Determining the gross and net weights
Place the empty weighing container or packaging on the scale and then press the
«ÆTÅ»
key briefly, or press the «PT» softkey if a known tare weight has already
been established.
Place the material to be weighed in the container, then…
… read the indicated net weight. Scroll on the «
» key.
Press the «Gross»
softkey. This function causes the gross weight to be displayed (the
“G” symbol appears and replaces the “Net” symbol).
Note: «Gross» is not given as a standard softkey and must be defined separately in
Vision Setup. In order to define the «Gross» softkey, see Chapter 5.5.7.
After a few seconds, the scale goes back automatically to net weight display.
2.6 Recording weighing results
Press the «
» key to send the current weighing result to the peripheral device
(printer, computer) via the interface.
Note: A multiple print out can be generated by entering a number with the numeric
keypad followed by pressing the «
» key. (only TLP/LP2844, TLP/LP2824,
MT8863).
Please refer to Chapter 5.3.4 for instructions on configuring the interface(s).

3 Enhanced functions
This Chapter describes the BBA462 / BBK462 features that simplify working with the application.
3.1 General Info
BBA462 / BBK462 provides several features which make working with the application easier.
Short Input Mode
For some BBA462 / BBK462 functions, it is possible to use a short-cut method of
user input.
As in the example for entering the pre-tare weight in Chapter 2.5.2, the normal
procedure for initiating user input is to press the function softkey first before entering
the data. However, it is also possible to key in the data first prior to selecting the
function the data is intended for.
.
1 5
This example shows how to enter the pre-tare weight using short-input mode.
While in standby mode, use the numeric keypad to enter the known tare weight in
the current weighing unit.
Then press the «PT» softkey or the «ÆTÅ» key to set this value as the pre-tare
weight.
The result is the same as in Chapter 2.5.2.
Short-input mode works with the following function softkeys:
«Smpl X» The value keyed in replaces the value of X (Chapter 5.5.1) and
performs a reference weight determination using the value as reference
number of pieces (Chapter 4.1.1). Default value for X is 10.
«Smpl n» The value keyed in will be used as the reference number of pieces for
the reference weight determination.
«APW» The value keyed in will be used as the average piece weight.
«ÆTÅ» The value keyed in will be used as the pre-tare weight.
«PT» The value keyed in will be used as the pre-tare weight.
«
» The value keyed in defines the number of printouts (only for label
printer).
«Æ0Å» The value keyed in defines the threshold for the Gross Weight Alarm.

Name
The name of the article can contain up to a maximum of 24 alphanumeric
characters. If 'Vision Setup Æ APPLICATION Æ Database Æ Article Æ Search
criterion' is set to “By name”, this parameter is used for searching in the article
database.
Number
The number of the article can contain up to a maximum of 24 alphanumeric
characters. If 'Vision Setup Æ APPLICATION Æ Database Æ Article Æ Search
criterion' is set to “By number”, this parameter is used for searching in the article
database.
METTLER TOLEDO BBA462 / BBK462 Chapter 3: Enhanced functions
21
Identification / ID1 and ID2
Additional identification parameters for the article that can contain up to a maximum
of 24 alphanumeric characters. These parameters could be used to provide
additional information about the article in the report printouts.
Tare
Pre-defined tare weight for the article. The pre-defined tare weight can both be
weighed-in or entered manually. Enter the weight value manually, in case the tare
weight is already known.
APW
Define the average piece weight of the article. It is possible to set the average piece
weight for the article by performing a reference weight determination (Chapter 4.1.1)
or by manually entering a known piece weight (Chapter 4.1.2).
Sample size
Define the reference number of pieces. This value will override the one set in 'Vision
Setup Æ APPLICATION Æ Counting ÆSample_X' (Chapter 5.5.1) while the article is
active.
PW optimization
The correction factor for optimizing the piece weight. The new value of the APW will
be adjusted by this factor in relation to the previous APW. Note: This works only if
PW Tol+ and PW Tol- are set and the APW is within the tolerances, and also if a
reference quantity (reference number of pieces) is defined.
See also below Example.
PW Tol+
The upper limit for a new average piece weight. If the new piece weight is above this
value, a warning will be displayed prompting the operator whether or not he wants to
accept the new piece weight. Note: APW must already be defined before setting the
PW Tol+, otherwise the PW Tol+ entry will be cleared.
PW Tol-
The lower limit for a new average piece weight. If the new piece weight is below this
value, a warning will be displayed prompting the operator whether or not he wants to
accept the new piece weight. Note: APW must already be defined before setting the
PW Tol+, otherwise the PW Tol+ entry will be cleared.

Example: In order to have the wearing down of the filling machine reflected, the
already existing value should be rated higher with 20% whereas the new piece
weight is rated with 80%.
To ensure that only 'good' pieces are used to build a new reference, they are only
allowed to derive max. 5% from the currently saved average piece weight.
Currently saved average piece weight = 0,1000kg
PW Optimization = 80%
PW Tol + = 5%
PW Tol - = 5%
New piece weight = 0,0970kg ( = within the tolerance +/- 5% of 0,1000kg)
=> new piece weight in the database = 0,0976kg (0,1000kg x 20% + 0,0970kg
x 80%)
Filling/checkweighing nominal
The nominal value used for the filling (Chapter 4.9) and checkweighing (Chapter
4.10) applications. It is possible to define the nominal value in pieces or as weight
value. This parameter must be filled in first before defining Tol+ and Tol-.
Note: If a target weight is defined this value will be used for the “accumulation to
target” function (see chapter 4.8).
Filling/checkweighing Tol+
The upper limit for filling (Chapter 4.9) and checkweighing (Chapter 4.10)
applications. It is possible to define this parameter as an absolute value, relative to
the Nominal, or as a percentage of Filling / Nominal.
Filling/checkweighing Tol-
The lower limit for the filling (Chapter 4.9) and checkweighing (Chapter 4.10)
applications. It is possible to define this parameter as an absolute value, relative to
the nominal, or as a percentage of nominal.
Accumulation
- Accumulation total net
The total net weight for the Accumulation application (Chapter 4.7)
- Accumulation total gross
The total gross weight for the Accumulation application (Chapter 4.7)
METTLER TOLEDO BBA462 / BBK462 Chapter 3: Enhanced functions

- Accumulation total pcs.
The total number of pieces for the Accumulation application (Chapter 4.7)
- Accumulation total lot
The total number of lots for the Accumulation application (Chapter 4.7)
Custom Unit
This application enables the user to define any unit (mass) for each article. (See also
Chapter 4.11).
Unit
Short-cut for the custom unit. This name can contain a maximum of seven
characters.
Factor
Factor of the custom unit. This can be determined or manually keyed in, in case it is
already known. This menu appears only if "Unit" is chosen.
Note
If a piece weight was entered for an article, the number of pieces is used for recalling
and defining the free unit.
Format
The type of format in which "Custom Unit" should be displayed.
3.2.3 Erasing of individual article attributes

Note: If 'Vision Setup Æ APPLICATION Æ Database Æ Article Æ Search criterion' is
set to "By number", BBA462 / BBK462 will ask you for the Number. Please note that
Article Name cannot be used also as a Number.
From this point on, the procedure is the same as defining a normal article (Chapter
3.2.2).
Note however, that the parameter APW is already defined and its value is set to the
APW that was active before «SaveAs» was pressed.
Aside from the APW, the article parameters that will also be saved are Tare, Sample
Size, the Filling/Checkweighing parameters, and the Accumulation parameters.
3.3 Gross Weight Alarm
Using the Short-input mode (see chapter 3.1) it is possible to define a Gross Weight Alarm. In case it is defined, there will be an
uninterrupted alarm beep as soon as the gross weight reaches the defined threshold. The beep sound will stop as soon as the
weight is either below the threshold or any key is pressed.
Note: After switching off the alarm using a key press, it will only become active again if the gross weight felt under the threshold
for a while before reaching it again. The Gross Weight Alarm can be deactivated by the 'C' key or by setting the threshold
parameter to 0.

3.4 SmartManager
To make working with the article database even easier, as well as to save the settings of the scale and its configuration, the
BBA462 / BBK462 comes with its own (optional) computer program (SmartManager). SmartManager requires MS Windows XP
or 2000. This program offers you the possibility to administer and manage your article data and also gives you the ability to
import and export files using MS Excel. For Configuration and operation please read the operator manual of the SmartManager
software.
BBA462 / BBK462 is able to get direct and immediate access to archived database using SmartManager. BBA462 / BBK462
functions in this case, as "Client". Hence it directly gets hold of data on an external database. In this mode, its own internal
Database will not be used and will stay unchanged. Please make the necessary settings of "Access" on "External" in Vision Setup
Æ APPLICATION Æ Database.
This functionality is also possible to connect a scale that has access to its own database, with several scales. If the internal
database of BBA462 / BBK462 is being used, SmartManager can create a backup copy of the database and this will be played
back again on the scale.
3.5 FlashLoader
The BBA462 / BBK462 software is stored in flash memory and the FlashLoader program enables you to upgrade the software of
your scale when updates are available.
Note: This should only be operated by authorized personnel. You should always make a back-up copy of your data prior to
performing this procedure.
To be able to update your software using the FlashLoader, you will need the following:
• PC with Microsoft Windows ® operating system (version 2000, or XP)
• Computer-to-scale connection cable (RS232 cable, 9-pin sub-D plug m/f, order number 00410024)
• FlashLoader program

4 Application
Your scale has a number of powerful application functions that can be activated in the menu (see Chapter 5.5.1). This
chapter describes the some of the functions that have been activated at the factory.
4.1 Counting pieces into a container
Place empty container on the scale and tare with the «ÆTÅ»
key.
Note: If the automatic taring function is active (Chapter 5.4.3), you need not press
the «ÆTÅ»
key, because the scale registers the tare weight automatically as soon
as the container is placed on the weighing pan.
Before your scale can be used for counting parts, it must know the average piece
weight (the so-called reference). The reference is then used to do the counting. The
reference can be determined by placing a number of pieces on the scale. If the piece
weight is known, it can be manually entered and used as the reference.
4.1.1 Determining the reference by placing pieces on the scale
The softkeys "Smpl X" and "Smpl n" are already given as standard function keys. In case they are not visible on the display,
define a softkey for "Smpl X" and "Smpl n" in the softkey configuration (See Chapter 5.5.7). After the softkeys have been defined,
do the following steps:
…appears on the screen (standard setting for Smpl X = 10)
Note: The standard value for "X" in Smpl X can be defined in Setup (see Chapter
5.5.1)
…place 10 pieces of materials to be weighed to determine the reference weight.
METTLER TOLEDO BBA462 / BBK462 Chapter 4: Application
27
Press the «Smpl 10» key.
Note: If a different number of pieces has been placed on the scale, please use the
Short Input Mode (see Chapter 3.1). The value that you have entered for "X" is still
saved, and will not change until after you overwrite it with a new value.
A reference weight has been established.
If a different number of pieces has been placed on the scale, press the «Smpl n»
key and choose from among the choices of 5, 20, 30, 40 or 50 pieces. If the
number of pieces is different, choose the «Var» key and enter the desired number of
pieces.
Note: The Short Input Mode is also available for the functions «Smpl X» and
«Smpl n» (see Chapter 3.1).
Once a reference has been determined, you can use the «Weigh» key to switch back
to the weight display at any time.
Note: This function is not given as a standard function key, because Gross, Tare and
Net will be continuously shown on the upper left of the display. To activate it,
proceed similar like activating « Smpl X» or « Smpl n» (see Chapter 5.5.7).
Press «Count» key to switch back again to counting mode.
You can use the « » key to transmit the piece counting result via the interface to
a peripheral device (printer, computer) (for sample report see Chapter 6.2).
4.1.2 Entering the reference when the piece weight is known
The softkey "APW" is already given as a standard function key. In case it is not visible on the display, define a softkey for "APW"
in the softkey configuration (See Chapter 5.5.7). After the APW softkey has been defined, do the following steps:
In standby mode, press the «APW»
key.
Enter piece weight, example: 0.02931 kg

Counting out pieces from a weighing container differs in a few essentials from counting them in (Chapter 4.1).
4.2.1 Determine reference by removing pieces
…initially appears on the screen.
Place the full weighing container on the pan and tare the scale with the «ÆTÅ»
key.
… appears on the screen again.
Remove the reference number of pieces from the weighing container.
Remove further pieces until the desired number has been reached.
… a negative weight value appears on the screen.
METTLER TOLEDO BBA462 / BBK462 Chapter 4: Application
29
Press the «Smpl 10» or «Smpl n» keys to determine the reference, as described in
the previous chapter.
The scale is now ready for piece counting.
4.3 Reference optimization
Reference optimization serves to enhance the accuracy of the average piece weight by re-calculating it using a greater number of
reference pieces. Reference optimization can be performed either manually or automatically.
Manual Reference Optimization
Define a softkey for Reference Optimization in the softkey configuration (See Chapter
5.5.7). The Reference Optimization softkey is displayed as «PW Enh» and it will only
be active while in piece counting mode. If the scale is in weighing mode, this softkey
will not appear even if it is part of the softkey configuration.
To perform a reference optimization at any time, press the «PW Enh» softkey. The
average piece weight will be re-calculated using the current weight and the current
number of pieces on the scale. At each optimization, the message “PW Enh” appears
briefly and the new total number of pieces is then displayed.
Automatic Reference Optimization
No action is required during operation for automatic reference optimization and it
functions both in "Counting in" (Chapter 4.1) and "Counting out" (Chapter 4.2). The
“Auto OPT” symbol (located near the lower right corner of the screen) appears in the
display indicates that automatic reference optimization is switched on.
Each time you place additional parts on the scale, it optimizes automatically. You do
not have to press a key to perform optimization. At each optimization, the message
“PW Enh” appears briefly and the new total number of pieces is then displayed.
Note: Automatic optimization only functions if the number of additional pieces placed
on the scale is not greater than the number already on the weighing pan. If t the
differences between the parts are too big, the reference optimization will not be
executed.
4.4 Minimum sample weight
To ensure that a more accurate average piece weight is attained during reference weight determination, it is possible to set a
desired minimum percentage accuracy as determined by the reference weight placed on the scale. To enable minimum sample
weight checking, set 'Vision Setup Æ APPLICATION Æ Counting Æ Min. Sample WT' (See Chapter 5.5.1) to the desired
percentage accuracy.
To be able to view the percentage accuracy for a reference weight determination, set 'Vision Setup Æ APPLICATION Æ Counting
Æ Accuracy Disp.' (See Chapter 5.5.1) to 'On'.
In this example, the minimum reference weight was set to 99.5% and accuracy
display is active.
Chapter 4: Application METTLER TOLEDO BBA462 / BBK462
30
10 samples were placed on the scale and «Smpl 10» was pressed.
BBA462 / BBK462 calculates the average piece weight as discussed in Chapter
4.1.1 but it has determined that the percentage accuracy for the reference weight is
below the value set as Minimum Sample Weight.
It will calculate the number of pieces that you have to place on the pan to reach the
desired percentage accuracy.
After placing the specified number of pieces on the scale, the average piece weight
will be optimized (Chapter 4.3) and, since accuracy display is active, the percentage
accuracy will be displayed for approximately 4 seconds.
Note that in this example, the percentage accuracy is at 99.54% which is above the
desired minimum sample weight of 99.5%.
BBA462 / BBK462 is now ready to perform piece counting using the optimized
average piece weight.
It is possible to override the minimum sample weight checking by pressing the «C»
key when you are prompted to add pieces on the scale. This will enable you to use
the calculated piece weight, but note that a "*" appears on the display to indicate that
the sample weight is below the desired percentage accuracy.
Adding mode works both with "Counting in" (Chapter 4.1) and with "Counting out"
(Chapter 4.2).
4.5 Using the info key
Use the «
i» key to call up additional information as defined in the Info/Help menu under Application (Chapter 5.5.8).
i
In this example, Info lines 1 to 4 were configured to show the gross weight, date,
time, and percentage accuracy respectively.
Pressing the «
i» key will toggle between a screen that shows the default content of
the Info lines and another window that shows the additional information configured
such as the Gross Weight, Date, Time and Percentage Accuracy.
For a list of the additional information that can be displayed on the Info lines, please
refer to Chapter 5.5.8.
