The BC scale, like all METTLER TOLEDO products, is designed for maximum
durability and reliability in even the most demanding shipping applications. The BC
is manufactured in one of METTLER TOLEDO’s ISO 9000 certified facilities so you
are assured to receive a high-quality product.
The BC scale is designed for robust use in parcel shipping, mail, and other light
industrial environments. BC scale models have a wide temperature and humidity
range and can be used on most unheated shipping docks.
Standards Compliance
FRI Susceptibility
The BC scale is a low profile, high precision scale designed to meet the needs of the legal-for-trade
parcel/manifest markets. The BC scale is capable of communicating through Toledo, SICS, and the
protocols of the major shipping carriers. The scale configuration can be customized, or easily
programmed through default communication settings. For preconfigured models, set up is simple
and easy with plug and play capability.
The BC scale family has 4 main models with maximum capacity at 15 kg (30 lb), 30 kg (70 lb),
60 kg (150 lb) and 150 kg (300lb). There are four postal versions with high resolution to process
letters as well as parcels. Typical BC models and platter options are summarized in Table 1-1.
Refer to the “Cap-inc” program block in Chapter 4 for the default capacity and increment settings.
The letter and parcel models provide the high resolutions required for shipping via postal and parcel
carriers. The parcel models offer superb reliability for retail stores, mail rooms and shipping
departments sending packages via parcel carriers or truck lines.

Power Requirements
Introduction
The BC operates on an input voltage of 5 VDC, at a current of 100-150 mA or less. The scale is
powered through the USB port on the scale so the USB cable is always used for power.
•
For USB operation, the scale communicates and is powered through the USB port of the PC.
With the low power consumption, the BC scale is within the USB power requirements for
connection to your PC without requesting additional power. Scale can also communicate and
be powered through a USB hub.
An external 5 VDC power supply is required for power to the BC scale for standalone applications,
RS232 applications, Ethernet applications or BlueTooth applications. For these applications, the
scale will be powered by the universal power adapter located in the scale’s shipping box. The wall
mounted transformer is rated between 110-220V and 50-60 Hz. Connect the USB cable to the PC
and then to the power supply. The power supply may have multiple plug adapters that can be
clipped to the transformer based on the available country outlet.
1.5.
Environmental Requirements
The BC scale is designed to operate in conditions of 10-90% relative humidity, non-condensing,
and a temperature range of:
BC-15
-10° to +40°C (+14° F to +104°F)
BC-3L
0° to +40°C (+14°F to +104°F)
BC-60
0° to +40°C (+14°F to +104°F)
BC-150
0° to +40°C (+14°F to +104°F)
BC-6L
0° to +40°C (+14°F to +104°F)
The shipping and storage temperature range is −20° to +60°C (-4°F to +140°F) at 0 to 95%
relative humidity, non-condensing.
The scale is designed for use in parcel shipping and other light industrial environments. This unit is
not intended for wash down or hazardous area operation, nor for operation in environments of
extreme heat, cold, or humidity (outside of the range listed above for each model).

2.2.4.
Scale Configuration
The patented GEOCAL™ feature provides the best scale accuracy. This feature precisely
compensates for gravitational differences between the factory location (where the scale was
calibrated) and the scale’s point of use location. Since the Earth’s gravity varies based on latitude
and altitude, the GeoCal feature allows the BC scale to maintain the sensitive factory calibration to
ensure the most accurate weighting results. The GeoCal is part of the BC “boot up wizard”. With the
proper code, the scale re-calibrates mathematically and is ready to be sealed for legal for trade
applications.
For Legal-For-Trade applications, contact your local Weights and Measure office for additional
requirements and certification.
Visit www.ncwm.net/state for listing of the US Weights and Measure offices by state.
2.2.4.1.1.
GEO Calibration Values
Refer to Appendix G for a table of regions and corresponding GEO codes.
2.2.4.1.2.
Graphical Display
1. Observe the display when the scale is first powered up:
If 0.00 displays, then GEOCAL is not activated, and no code is required. Proceed to step 7.
Refer to sections 4.2, 4.3, 4.4, and 4.11.5 for calibration procedures. For best accuracy, the
scale should be calibrated on-site by a trained technician using certified weights.
If the initial boot screen (Figure 2-7) is displayed, the scale will prompt for the entry of a Geo
code. If enabled, the scale will also prompt for the entry of language, unit selection and the
manifest software program the scale will communicate to.

Installing Accessory Items
2.3.1.
Remote Displays
METTLER TOLEDO offers several options for displays: they can be base-, wall- or tower-mounted.
Power down the scale before plugging in a remote or base mounted display. If display is
plugged in “Hot” and is displaying erratically, power down the scale for 10 seconds and
reboot.
•
The base mounted display has the display mounted to the scale base.
•
Wall mounted displays allow the weight to be seen at eye level.
•
Tower mounted display is typically used for mounting on a counter top.
Remote displays are often used for better visibility. Most scales are ordered with a base-mounted
display. Remote wall or tower displays are typically used where package size is large enough to
obstruct the view of the scale’s base display. In Legal-for-Trade applications, a customer-facing
display is typically required in addition to the operator-facing display.
2-10
METTLER TOLEDO BC Shipping Scales Service Manual
30126862 | 02 | 12/2016
There are two display connectors (RJ45) on the scale, and it can support two displays. Each
display will have its own cable.
There are two display types, the graphical display model 0271 and the basic display model 0270
(seven segment LCD). The display types can be mixed, except in dual tower displays (where a
single tower supports two back-to-back displays).
30126862 | 02 | 12/2016
•
The 0271 model consists of a monochrome graphical display. The 0271 can show
special messages and the added value applications. The 0271 display will recognize the
scale and display the correct capacity and increment.
•
The 0270 model is for basic weighing only and needs a printed lens to show the capacity
and increment size. The display lens needs to be matched to the scale capacity and
increment size (build). So changing the scale “build” requires a new Lens for the 0270
model.

If the unit fails to capture zero, reboot the scale by cycling power (unplug the Wall transformer
and/or USB cable). Reconnect the power source. If the scale still fails to capture zero, recalibration will be required. The difference in dead load between platter types can be substantial
and outside the power-up criteria of the scale.
2.3.3.
Conveyor Drop-In Kit for BC-150
The Conveyor drop in kit includes two adjustable width rail brackets that allow a BC-150 scale to
be integrated into a standard gravity conveyor, that measures between 22 and 32 inches wide
(between the conveyor frame rails). The kit is designed for standard conveyors that use 1.9”
diameter rollers on a frame that supports 1.5” spacing increments.
NOTICE
DO NOT ATTEMPT TO INSTALL THIS KIT IN A POWERED CONVEYOR.

The BC-150 scale can be mounted lengthwise or transverse in the conveyor frame for the
Ball Top Platter. The ball-top platter allows packages to be rotated easily when on the
scale. This option is commonly used when packages have labels that must be scanned at
the shipping station.
•
The BC-150 scale should always be mounted lengthwise when used with the roller-top
platter. The roller-top platter is commonly used when packages are significantly larger than
the scale.

Operation and Maintenance
This chapter provides operating instructions for the BC scale during normal
operation. Before weighing parcels, the BC Scale should be configured properly
and power applied as instructed below. How the scale operates is based on the
parameter settings selected in the setup program. Refer to Chapter 2 for
installation instructions and Chapter 4 for advanced programming of the setup
parameters.

3.1.
Power-Up Sequence
The scale is energized whenever power is applied to it (plugged in), and de-energized when
power is removed (unplugged).
A power adapter is not needed for USB connection to a PC since the power requirements are
within standard USB specifications of 100ma.
The PC can provide additional power up to 500 mA, required for scale options.
In the unlikely event that the PC is not providing power through the USB port, a powered USB
hub can be used.
Special software versions may be used for specific applications.
If a power switch is required, use a terminal strip with a power switch.
Power is applied by plugging the scale into a power source. Since the scale is a USB peripheral
device with low power consumption, it does not have a typical on/off switch. The scale operates
similar to a USB keyboard or PC mouse where a power switch is not needed. To power up the
scale:
USB communication
Plug in USB cable to an energized PC. Power can also be
supplied from a powered USB hub between the scale and PC.
Other communication (RS232, Plug in USB cable to the power adapter and then plug the power
Ethernet, Bluetooth)
adapter into an AC outlet.
Note: For units with a graphical backlight display, the backlight can be turned off in the
parameter settings. HOME > SETUP > DISPLAY > BCKLGT.
When using other communication types than USB, the power input to the scale is through the USB
cable and a power adapter with USB connection (like many cellphones).

Operation and Maintenance
The BC goes through a power-up sequence each time power is applied. The power-up sequence is
as follows:
1. All pixels or segments of the display characters are activated. This verifies operation of all
display segments.
2. The scale displays the software part number followed by the software revision status. An
example of a Software number for the BC model is 30233384, version 1.00.XXX.
3. The scale then captures zero based on the Power Up zero setting, which can be ±10% or 20%
of calibrated capacity, and is ready for normal operation.
4. To turn off the scale, unplug the power source to the scale:
3.2.
USB
Unplug the USB cable (and power adapter if used).
Other (RS232, Ethernet, Bluetooth)
Unplug the power adapter from AC outlet.
Keypad and Display
The BC scale includes a monochrome graphical display with backlight (Version 1.00.00X), and a
navigational keypad with a central “Enter” key. The keypad is similar to a TV remote control and
can scroll up, down, right, and left between soft selection keys on the display. An item is selected
by scrolling to its position and pressing the center “Enter Key”. The keypad is used for scale
operation as well as configuration. To turn on or off the backlight, press left arrow key for 3
seconds.
A Basic 7 segment 0270 LCD display can also be used for weight display only. The 0270
display is very limited in set up capability, and has a zero key and unit switching keypad. See
section 3.7 and 4.14 for additional instructions.
Press the navigation keys by placing one finger behind the bottom-right corner of the display to
support it while pressing the keys with the thumb (similar to texting on a cellphone).

right two soft keys are displayed, the operator has functions for:
3.4.1.
•
Unit switching
•
Zeroing the scale
Parcel Weighing
To weigh a package:
1. If the display shows a weight when there is nothing on the platter, press ZERO to capture zero.
The display will read 0.00 and, if enabled, a center of zero icon ( >0< ) will appear on right
side of screen.
2. Place the parcel to be weighed on the platter. The display reads the parcel weight with
corresponding units of weight (lb. or kg) in smaller font.
3-8
METTLER TOLEDO BC Shipping Scales Service Manual
30126862 | 02 | 12/2016
3. Record the parcel weight as needed, then remove the parcel from the platter.
You may wish to recapture zero periodically when the scale is in continuous use. It is not
necessary to press ZERO before each transaction.
3.4.2.
Zeroing the Scale
Most scales are set up to re-zero if weight is within 2% of the scale capacity. If the zero change
exceeds the 2% limit, the scale will not capture zero. In this case, cycle power or recalibrate.
Remove all weight and debris from the scale platter and press ZERO to capture the zero weight. The
BC display will indicate a zero reading 0.00 and a center of zero icon ( >0< ) on the right side of
the screen. The scale will re-zero provided the weight is within the designated percentage of scale
capacity as programmed in setup (Home > Setup > Scale > Zero > Power-Up Zero).
If the scale does not capture zero with the above procedure:
1. Unplug the scale, remove all weight from the platter, make sure nothing is touching the platter,
and reconnect the power.
2. If cycling power does not work, recalibrate the scale as described in Chapter 4.
3.4.3.
Unit Switching
Some selections made in setup, may inhibit unit switching and the symbol would not be shown
on the weighing screen.
The BC scale allows the displayed scale weight to be viewed in primary and secondary units. Unit
switching must be enabled in setup mode to convert and display in secondary units. The primary
units are also designated in setup. Refer to section 4.11.4 in Chapter 4.
To switch units:
1. With scale weight displayed, press the UNITS key. The BC scale automatically converts the
displayed primary weight to the secondary weight unit.
2. Press UNITS again to switch the scale back to the primary units. The weight shown on the
display will be the primary units as indicated by the weight symbol (lb / kg).

Home > OPMode, where function parameters are set. This area can be password protected by
a manager.
Basic Weighing cannot be disabled. If Basic Weighing is the only mode available, the Mode softkey
will not be shown.
3.5.2.
Weight and Tare Mode
Weight and Tare can be set for either Auto Clear or Keypad Clear in setup at Home > OPMode
> WT-Tare > Enable.
The Weight and Tare mode allows the container weight to be subtracted from the gross weight to
provide the Net weight of the contents. Enable the Mode as described in section 3.5.1, above.
1. If the display shows a weight with nothing on the platter. Press ZERO to capture zero. The
display will read 0.00 and, if enabled, a center of zero icon ( >0< ) will appear at lower right
on the screen.
2. Place the container to be used on the platter. Scroll to the Tare softkey and press ENTER to tare
the container. The display will read 0.00 with the container still on the scale, and an N for NET
weight will appear. Add material to the container. The display reads the NET weight of the
material with corresponding units of weight (lb. or kg) in smaller font.
3. Record the NET weight as needed, then remove the container from the platter.
4. If Auto-Clear Tare is selected, the tare will be cleared once the scale sees a zero gross weight. If
Keypad Tare is selected, the tare is cleared only when the TARE softkey is pressed with nothing
on the scale platter. Keypad tare is used when the same container will be used for multiple
weighments.
3.5.3.
Label Offset Mode
Label Offset can be set for an Auto Clear or Keypad Clear in Home > OPMode > LabOff >
Enable.
Parcels are always weighed and dimensioned by the carriers, and if the addition of the packing list
causes the parcel to weigh into the next pricing tier, the carriers will implement back charges. With
Carrier pricing tiered at every whole pound or ½ kg, there is plenty of opportunity for back-charges
to occur on an average shipping day. For “Prepay and Add” parcels, the back charges cannot be
recovered.
Label Offset mode is designed to minimize these back-charges from Carriers in a non-legal for
trade application. It is similar to a Tare but it adds an offset instead of subtracting one. This mode
allows compensation for items added to the parcel after the final weight was taken for weighing and
pricing of the shipping service. Typical items are labels and packing lists which can equate to
several scale increments. This is important in “Pre-pay and Add” transactions where several US
dollars could be lost per back-charge.
In this mode, the displayed weight is the gross weight plus the offset weight tared into the scale.
When this mode is in use, the display will show G+ and the secondary line will show OFFSET =
0.45 lb (where the document weight is 0.45 lb). The document weight should be a representative
sample to cover the majority of weighments. Enable the LabOff Mode as described in section 3.5.1,
above.

Operation and Maintenance
1. If the display shows a weight with nothing on the platter. Press ZERO to capture zero. The
display will read 0.00 and, if enabled, a center of zero icon ( >0< ) will appear on right side of
screen.
2. Place the documents to be used on the platter. Scroll to the Tare softkey and press ENTER to
input the document weight. The display will read twice the document weight with the document
still on the scale. The G+ will be displayed. Remove the document from the scale.
3. Add a parcel to the scale. The display will show the gross weight of the parcel plus the
document offset. The corresponding unit of weight (lb. or kg) is shown in smaller tyepface.
4. Record the G+ weight as needed, then remove the parcel from the platter.
5. If Auto-Clear is selected, the offset will be cleared once the scale sees a zero gross weight. If
Keypad Clear is selected, the offset is cleared only when the TARE softkey is pressed with
nothing on the scale platter. Keypad Clear is used when the same representative offset will be
used for multiple weighments.
3.5.4.
Product Verification Mode
Product Verification mode is designed for warehouse packing stations to verify the weight of each
item placed added to the box during packaging. Weight verification eliminates mistakes. This mode
will communicate the gross weight and the positive change in weight from the last stable weight.
Gross weight is indicated by the “G” on the display, and is in the large typeface. The verification
weight is shown below the Gross weight in smaller typeface.
During the packing of the box, the incremental weight can be communicated to a connected PC and
merged with the last bar code scan, to confirm that the correct item was placed in the box. When
the pick and pack order is complete, final packaging can be added, the box sealed, and final gross
weight communicated for shipping services. Enable the ProdVy mode as described in section
3.5.1, above.
If the display shows a weight with nothing on the platter, press ZERO to capture zero. The
display will read 0.00 and, if enabled, a center of zero icon ( >0< ) will appear on right side of
screen.
If an item is removed from the box it will show a negative incremental weight.
1. Place the packing box on the scale; note that the gross weight and incremental weight are the
same. Scan the first item to be packed, and add the first item to the box. In large font, the
display will show the Gross weight of the box and first item. The incremental weight will show
only the first item.
2. Record the + incremental weight as needed.
3. Scan a second item and add it to the box. In large font, the display will show the Gross weight
of the box, first item and second item. The incremental weight will show only the second item.
4. Record the + incremental weight as needed.
5. After weighing all items and sealing the box, record the gross weight for shipping.
6. Remove the parcel from the scale. Scale will zero the Gross weight and incremental weight

30126862 | 02 | 12/2016
3.5.5.
Take-Away Mode: Differential Weighing
Differential Weighing mode is similar to Product Verification mode, but items are removed instead
of added. Differential weighing is designed to accommodate a container of letters, where the whole
container can be placed on the scale, and weights of individual letters are communicated as each
is removed from the container. The container can be tared if necessary.
This mode communicates the gross weight (or Net weight, if a tare was taken) and the negative
change in weight from the last stable measurement. Gross/Net weight is indicated by the G/N on the
display, and is in the large font. The differential weight is shown below the Gross/Net weight in
smaller font. Enable the TakeAW mode as described in section 3.5.1, above.
If the display shows a weight with nothing on the platter. Press ZERO to capture zero. The
display will read 0.00 and, if enabled, a center of zero icon ( >0< ) will appear on right side of
screen.
If an item is removed from the box, a negative incremental weight will display.
1. Decide if a container is to be used or not:
a. If yes, place the container on the platter. Scroll to the Tare softkey and press ENTER to tare
the container. The display will read 0.00 with the container still on the scale, and display
an N for NET weight. Add letters to the container. The display reads the NET weight of the
material with corresponding units of weight (lb. or kg). The tare value is still shown in the
line below the Net weight on an increasing weight. It will show the decremented weight
once a letter is removed.
b. If no, place the letters on the platter. The display reads the Gross weight of the material with
corresponding units of weight (lb. or kg).
2. Remove a letter and note the decremented weight in smaller font below the Gross/Net weight.
3. Record the decremented weight as needed.
4. Remove another letter and record the decremented weight as needed.
5. Remove additional letters until the Net value or Gross value is zero.
6. If Net is zero, remove the container, and tare the scale (scroll to the Tare softkey and press
ENTER) with nothing on the platter.
3.5.6.
Bulk Mail/Counting Mode
Mettler Toledo offers a wide variety of counting scales. For higher accuracy or functionality,
consult your local representative.
Bulk Mail/Count can be set at Home > OPMode > COUNT > Enable. Once Enable is pressed,
options for the APW (Average Piece Weight) quantity are shown.
For best results, zero the scale first to clear the tare before calculating a new APW.
BC scales will display the APW to two additional decimal places then the increment size. A
0.02 lb increment will display the APW to 4 decimal places per USPS requirements.
The BC scales have a simple counting mode designed for bulk mailers and warehouse packing
stations to determine non-critical quantities. Accuracy of the counting mode is based on the
30126862 | 02 | 12/2016
METTLER TOLEDO BC Shipping Scales Service Manual
3-13
Operation and Maintenance
accuracy of the load cell. Bulk Mail/Counting mode allows for a sample of identical parts or letters
to be weighed, and the Average Piece Weight (APW) recorded, to four decimal places. As more
identical parts are added to the scale, the scale will calculate the estimated quantity by dividing the
Net weight by the APW.
Enable the Bulk Mail/Counting mode as described in section 3.5.1, above.
1. If the display shows a weight with nothing on the platter. Press ZERO to capture zero. The
display will read 0.00 and, if enabled, a center of zero icon ( >0< ) will appear on right side of
screen.
2. Decide if a container is to be used or not:
a. If yes, place the container on the platter. Scroll to the Tare softkey and press ENTER to tare
the container. The display will read 0.00 with the container still on the scale. The left side
of the display indicates an N for NET weight. The units of weight (lb. or kg) are indicated
on the right side. The tare value is still shown in the line below the Net weight.
b. If no, go to step 3. The display reads the Gross weight of the material with corresponding
units of weight (lb. or kg).
3. Scroll to the APW softkey. Once the softkey is highlighted, the number of sample pieces to be
added (i.e. 10) to the scale will display at the bottom of the screen. Place this quantity of items
or letters on the scale. You will see the weight increase. Now, with the APW softkey still
selected, press ENTER. The sample count (i.e. 10) will be shown on the display as well as the
Average Piece Weight.
4. Add additional items or letters to the scale and the new count or quantity will automatically be
displayed.
5. Record the count and APW weight as needed.
6. Remove the items from the scale. The APW will still be active. Add additional identical items for
a new count with the same APW.
7. To calculate a new APW, remove all items from the platter. Put the new sample quantity on the
scale and press ENTER to recalculate the APW.
8. Scroll to the ZERO softkey and press ENTER. The count will return to zero. Scroll to Tare or APW
and enter a new COUNT sequence.
3.5.7.
Price Mode
The Price mode is designed for retail counters and legal-for-trade applications. When this mode is
enabled, a connected local PC will provide the scale the calculated total price of the current
weighment. The weight and price will appear on the operator graphical display, and on the remote
customer graphical display. No operator action is needed except to enable the Price Mode as
described in section 3.5.1, above.
For the price to be displayed, the parcel must be on the scale (non-zero weight). Once the scale
returns to zero, the price is erased.
Refer to Appendix F for the commands required to display the weight. To disable the Price mode,
scroll to the MODE Softkey and enable a different mode.

Cleaning and Regular Maintenance
The BC scale is basically maintenance free.
Depending on environmental conditions, it may be necessary to wipe the keypad and platter with a
clean, soft cloth that has been dampened with a mild cleaner. Do not use any type of industrial
solvent such as toluene or isopropanol (IPA). These may damage the display finish. Do not spray
cleaner directly onto the display LCD. Make sure no overspray hits the cable connectors or circuit
board.
The set up menu includes a Maintenance page (Figure 3-15) to assist with the longevity and
accuracy of the scale. The maintenance setup screens are also described in section 4.12 of
Chapter 4.

4.7.1.
WtTare
Tare mode is used when the application needs a net weight of contents without container weight.
The scale will allow the container to be subtracted from the Gross Weight. The tare value is created
by placing the container on the scale and pressing the T soft key. The display will then display an N
for Net weight.
To disable tare, press the T softkey again when the platter is empty. Tare can also be set to clear
automatically, so that when the scale sees zero gross weight the Tare is cleared. Auto clear is used
for a single weighment. Key pad Tare can be used for multiple weighments with the same
container. To enable the Tare function, scroll to WtTare and press ENTER.
1. Select Disable or Enable, and press ENTER.

2. If Disabled was selected, Exit the screen. Otherwise, the scale will prompt for the type of
Tare. Scroll to and highlight either Auto-C (auto-clear) or Key-T (keypad tare).
3. Press ENTER.
4.7.2.
Hold
The hold function will retain the displayed weight for a specified length of time after the weight has
been removed from the platter. This function is used when scale weight is being recorded manually,
and a large box makes it impossible to see the display. To enable this function, access the Operate
Mode screen (Figure 4-10), scroll to Hold, and press ENTER.
1. Select Disable or Enable, and press ENTER.
2. If Disabled was selected, Exit the screen. Otherwise, the scale will prompt for the hold time
(HdTime) and stable time (stbTm).
3. Scroll to HdTime and press ENTER. This value determines the amount of time, in seconds,
for which the scale will retain the displayed weight after it sees a significant change in
weight. Options are:

2 sec

5 sec

7 sec

10 sec

15 sec

20 sec
4. Highlight the desired value and press ENTER.
5. Scroll to stbTm and press ENTER. This value determines the amount of time the weight
must be steady on the platter (without motion or vibration) before the scale will recognize it
as the final weight. Options are;

0.5 sec

1.0 sec

1.5 sec

2.0 sec
6. Highlight the desired value and press ENTER.
7. Press ENTER again to exit the screen.
4.7.3.
LabOff
The Label Offset Mode is similar to the Tare mode, except the weight amount is added to the gross
weight to give a Gross+ value. Label Offset mode allows a shipper to compensate for any packing
labels, box tape, or other items added to the parcel after final weighing for price determination. This
is important for Pre-pay and Add scenarios, where Carriers will back-charge for a higher weight
than the one originally determined when the parcel was shipped.
30126862 | 02 | 12/2016
METTLER TOLEDO BC Shipping Scales Service Manual
4-11
Technical Manual
The Offset value is determined by placing a sample load on the scale and pressing the T softkey.
The display will display G+ (for Gross Plus weight).
The offset can be disabled by pressing the T soft key button with nothing on the platter, or it can be
set to Auto-Clear so when the scale sees zero gross weight the Offset is cleared. Auto-clear is used
for a single weighment. Keypad Tare can be used for multiple weighments using the same
container. To enable the label offset function, scroll to LabOff and press ENTER.
1. Select Disable or Enable, and press ENTER.
2. If Disabled was selected, Exit the screen. Otherwise, the scale will prompt for the type of
clearing function – Auto-C or Key-C.
3. Select the desired option and press ENTER. Press ENTER again to exit the screen.
4.7.4.
TakeAW – Differential Weighing
Differential weighing is designed to accommodate a container of letters, where the whole container
can be placed on the scale, and the weight of each letter is communicated as it is removed from
the container. If necessary, the container can be tared. To Enable the differential weighing function,
scroll to TakeAW and press ENTER.
1. Select Disable or Enable, and press ENTER.
2. If Disabled was selected, Exit the screen. Otherwise, press the Enabled softkey a second
time to exit the screen.
4.7.5.
Price
When the price mode is enabled, the scale will accept communication of the calculated total price
of the weighment from a local PC. The scale will display the weight and price on the operator
display and the remote customer display, if one is attached. This feature is only available in MTSICS protocol. To enable the label offset function, scroll to Price and press ENTER.
1. Select Disable or Enable, and press ENTER.
2. If Disabled was selected, Exit the screen. Otherwise, press the Enabled softkey a second
time to exit the screen.
With Price mode enabled, the scale will look for a command from the PC, such as
GSPMNY"xxxxxx”, where xxxxxx denotes the price to be displayed, including the currency symbol
and decimal or comma. For example, if the PC sends GSPMNY"$12.40” , the $12.40 will be
displayed. Refer to Appendix F for additional details. The price will be displayed until the parcel is
removed and the scale returns to zero.
4.7.6.
Count
Bulk Mail / Counting mode allows for a sample of identical parts or letters to be weighed, and an
Average Piece Weight (APW) calculated to four decimal places. As more identical parts are added
to the scale, the scale will calculate the number of parts by dividing the Net weight by the APW. To
enable the counting function, scroll to Count and press ENTER.
1. Select Disable or Enable, and press ENTER.

Weight data can be sent, either by a keypad press or continuously
Serial
The SERIAL program block is used to configure RS-232 communications including Protocol used.
This set up will also apply to the Virtual Serial settings in USB applications, as well as the Ethernet
and Bluetooth options. Refer to sections 4.10.2, 0 and 4.10.4.
IMPORTANT: For successful communication between the scale and a PC, both the serial
parameters and the protocols in the scale and PC must match. The weight request command is
case sensitive. Thus, if a weight “request” command is a capital W, sending a lower case w
will not get a weight response from the scale.

USB
The USB screen allows various types of USB communication to be configured. These include
HIDPOS, Virtual Serial, and Keyboard Wedge.
The Home > Setup > Communication > USB screen includes the following options:
HIDPOS
HIDPOS is a standard Microsoft Human Interface Device protocol for Point-of-Sale
equipment which includes a scale. If the software on the PC is programmed for
HIDPOS, the connection is “Plug and Play” and no additional drivers are needed. In this
case, the scale operates as a USB peripheral to the PC.
To configure the parameter from the USB screen, scroll to HIDPOS and press ENTER. To
exit the page, press ENTER again to go back to the USB screen, or press the UP arrow
and select the desired page and press ENTER.
Virtua
The Virtual USB setting enables communication over a USB cable using a serial
protocol. No additional cabling or hardware adapter is needed, but a special software
driver is required for the PC. Refer to Appendix C for details.
To configure the parameter from the USB screen, scroll to VIRTUA (Virtual Serial) and
press ENTER. To exit the page, press ENTER again to go back to the USB screen, or
press the UP arrow and select the desired back page and press ENTER. The Serial
settings and protocol will apply. See SERIAL program block 4.10.1 above.
KBWed
The BC scale has the flexibility to configure the scale to operate like a Keyboard without
any additional cabling or hardware. In this setting, the scale is configured as a
keyboard in the HID of the PC. Weight is effectively “typed” into any software program
from the scale, as if the operator was typing in the weight using a keyboard. Keyboard
Wedge functionality is based on a QWERTY keyboard, except French language is
AZERTY
This setting is used in conjunction with the SendWT (send weight) command accessible
at Home > Setup > COMM. The scale can be configured for weight to be sent by
pressing the keypad, upon sensing a stable weight, or sent continuously.
Once the KB Wedge screen (Figure 4-20) is accessed, a further option appears: an
additional character can be designated after the weight data is typed, to index to the
next space in the program. Options are None, Tab and Return. In Excel, the Tab will
scroll one cell to the right. The Return will scroll one cell down.

Use GEO
The METTLER TOLEDO GEOCAL procedure, which prompts for the Geo-Code update on the first
power up, uses the USEGEO parameter.
In remote areas, it is expensive to send a service technician to the scale’s location. The Use GEO
function will update the GEO-code value for a location other than the calibration site. In countries
where W&M authorities allow this procedure, a certified technician can:

Set the GEO Code for the calibration location.

Calibrate the scale.

Reset the Geo code for the point of use location.

Seal the scale and fill out proper documentation.

Ship the sealed scale to the remote point of use location.
The USEGEO simplifies the resetting of the Geo-code while keeping record of the original calibration
GEO Code. Values can be viewed at Home > Info > Cal Info.
To configure the parameter:
1. In the Calibration setup screen (Figure 4-27), scroll to UseGeo and press ENTER.
2. A numeric box will appear on screen.

Figure 4-39: Center of Zero Indication
For example, on a scale with an increment size of 0.05 lb in normal rounding, debris on the platter
weighing 0.0249 lb would still display a zero weight, and the center of zero icon will display
whenever the debris weight is below 0.0125 lb.
4.11.6.3.
Automatic Zero Maintenance
AZM can be set to Disabl or Enable. When it is enabled, and the weight indication on a scale is
within a certain programmable band of zero but is not exactly at the center of zero, the scale will
automatically track itself back to the center of zero.
AZM typically works in a range of 0.5 divisions (the smallest scale increment).
4.11.6.4.
Power-Up Zero
Figure 4-40: Power-Up Zero Screen
Pwr 0 sets the range, in percent of scale capacity, within which the scale will capture zero when it
is first powered up. Options are:


Rounding
This parameter sets the rounding method used by the scale. Normal rounding means that with a
0.05 lb increment, 0.0250 will round up to 0.05, and 0.0249 will round down to 0.00.
Figure 4-41: Rounding Screen
The options for this parameter are:
Classi
Weight classifier rounding up; round up for values above zero (1+).
Used for basic weighing only.
Normal
Retail rounding: round up for values 5+.
Usps
USPS rounding within maintenance tolerances. Used for basic
weighing only.
Expand
Displays expanded weight, typically at 10x resolution.
Classifier and USPS rounding are used in basic weighing only.
Expanded weight displays the raw weight before rounding. It is not a legal rounding mode in
the scale.

Check Power Adapter
Contact METTLER TOLEDO for the correct power adapter part number. Using the wrong type of
adapter may damage the scale.
The BC scale can have either of two power sources, depending on its mode of communication:
USB
Does not require the power adapter. Scale is powered by PC.
RS232, Ethernet,
Bluetooth*
A power adapter is used with the USB cable to supply power to the scale.
Note: Scale is a low powered USB peripheral device. Like other USB peripheral devices
(Keyboard, PC mouse) the BC scale does not have a power switch. To power down, unplug
the USB cable.
If the graphical display has a backlight, the backlight can be turned off:
1. Press the left arrow key and hold for 3 seconds on software version 1.00.006 and higher
2. In the parameter settings HOME > SETUP > DISPLAY > BAKLGT (shown in figure 4-6) in
software versions below 1.00.006.
To see if the scale is powered, check the display for activity, and/or look at the connectors under the
scale. A green status light on the PCB behind the connectors should be lit or flickering, if the scale
is receiving power.
Figure 5-1: Green PCB Status Light Illuminated
If the scale is not powered, use the following method to determine if there is a problem with the
power adapter, the USB cable, or the scale:
1. Confirm that the AC outlet has power by plugging in another, functioning device.
2. Check the USB connections to the power adapter and the scale. Make sure the USB A connector
is firmly attached to the power adapter and the USB B connector is firmly attached to the scale
USB port. Plug the power adapter into the AC outlet.
3. If there is no power through the Power adapter, disconnect the serial cable, then disconnect the
USB A connector from the power adapter and plug it into a USB port on the PC.
4. If there is still no power, try another USB cable that is known to be functional. Connect the new
USB cable to the scale and PC.

If there is still no activity, consult a METTLER TOLEDO technician. The PCB may be damaged.
Blank Display
Service and Repair
If the scale’s display is blank:
•
Check that the scale is receiving power, and that the display cable is attached to the scale
base properly. Refer to section 5.1.2.
•
Look at the connectors under the scale to see if the green PCB light is energized (Figure
5-1). If the scale is receiving power, the green light should be lit or flickering.
•
For RS-232, confirm that the power adapter is plugged into a working AC outlet and the
USB cable is properly plugged into the power adapter and scale.
•
For USB, make sure the USB cable is pushed in all the way at both the scale and the PC.
Once it is verified that the scale is receiving power, and the display remains blank, check the
display cable at the connectors. Unplug the display by pushing in on the connector tab and pulling
back on the cable. Reinsert the display cable into the scale connector, making sure the tab clicks
into position.
If the display still does not work, connect the display to the secondary display connector.
If the display is still blank, it must be replaced. Scale display can be ordered under accessory
model 0271 for a graphical display or 0270 for 7 segment display.
5.1.5.
No Keypad Interaction
To test the operation of the keypad, remove power from the scale, then reapply it. With the unit
powered, allow the scale to go through its boot-up sequence, and then attempt to enter setup mode
by pressing and holding the UP key for 5 to 8 seconds. If the display does not display the Home
page, replace the display.
5.1.6.
Display Indicator Locked
A display test can be run to check the functionality of display pixels. This is the same test shown at
boot-up. Access Home > Setup > Maintc. Select dspTst and press ENTER. A series of test patterns
will display.
To test operation of the display indicator, remove power and then reapply it. With the unit powered
and display reading zero, add weight. If the displayed weight does not change, check the cable
connection from the load cell to the PCB. Disconnect and reconnect the cable. Refer to section 5.4,
Load Cell Replacement.
If the display appears to function but will not indicate a weight, replace either the load cell or the
PCB.
5.1.7.
Serial Communication Test with PC
This test does not apply if PC communication is via USB by HIDPOS or KB Wedge.
A HyperTerminal serial (RS-232) test can be conducted to see if serial communication problems
are occurring. This test can determine if the issue is with the scale connection / communication to
the PC, or if the issue is within the shipping software program itself.
5-4
METTLER TOLEDO BC Shipping Scales Service Manual
30126862 | 02 | 12/2016
Note: HyperTerminal is no longer standard in Win 7 or later versions of Windows. It can still be
obtained on-line or copied from an XP computer. Similar Programs such as PuTTY or MT
Albatross can also be used.
The HyperTerminal test will confirm
•
If the scale is properly connected to the PC
•
If the scale is able to communicate by serial RS232 to the PC
•
If the scale is able to display the correct weight
Run this test whenever it is unknown why the manifest or shipping software is not showing a
weight, or the proper weight, on the PC screen.
1. Connect the scale to the PC as shown in Figure 5-2. Note the COM port on the PC that the scale
is connected to; this information will be needed in step 5.

Update by Serial
The scale software is a .mot file. Simple Loader is a METTLER TOLEDO application used to load the
new software into the scale. The application can be downloaded from the METTLER TOLEDO
website at www.mt.com/ind-bc-scale. Click on the Download tab, select Simple Loader, and
download to a local PC folder.
This procedure requires a serial connection. An external USB-to-Serial adapter (such as
Keyspan USA-19HS) can be used if the PC does not have a serial connection to the scale. The
scale’s virtual serial setting will not function for this purpose, since it uses the USB port. Use
cable 64052046 (Old part number is 16317400A).
Please reference the operating instructions (Simple Loader Operating Instructions.pdf) additional
details are needed:
Check which PC COM port the scale is connected to.
On the PC, go to Start > Control Panel > Device Manager. Click on Ports and select the proper COM
port. Make sure no other serial program is using the same port as the scale. Shut down
HyperTerminal or any other serial tool before starting the firmware update.
Figure 5-5: Device Manager, Port Settings
Simple Loader program is based on the SICS protocol, but the scale will upload the firmware
regardless of what Protocol the scale is set for. If the SICS protocol is not used, an error message
107 will appear. This message can be ignored if the scale is not set up for SICS.

•
Stop bits (1, 2)
The scale only responds to commands from the Host, unless the Send Weight (Transmit) function
is activated. The Send Weight transmit capability can be done through a Keypad press, stable
weight, or continuous data output.
In addition, the BC scale supports multiple serial protocols including this Toledo protocol and SICS
covered in Appendix A , as well as the protocols for the major carriers.

Scale Status Byte Information
When communicating in host mode using the standard Toledo protocol, the BC may send status
bytes containing information such as motion and over/under-capacity conditions. The message
<STX>?<status byte><CR> indicates transmission of a status byte. The status byte sent is an ASCII
character that must be converted to binary form for decoding the bits. The ASCII character table with
binary conversion (given in the previous section) can be used to convert status bytes. The bits of
the status byte in the standard Toledo protocol are defined in Table A-2.

Calibrate Using Host Interface
The BC shipping scale can be calibrated using the host interface. The command to initiate the
calibration sequence is available in the METTLER TOLEDO command set. Calibration is based on
the current scale configuration for units and capacity/increment. These can be changed (through the
keypad or the host interface) before calibrating the scale through the host interface.
To calibrate using the host interface:
1. Remove the platter, break the legal-for-trade seal (if present) on the green cap, and remove the
green cap to give access to the PCB.
2. Press the Cal button SW-2. Refer to the calibration diagram in Chapter 4 of this manual. DO
NOT ENTER SETUP MODE. The BC does not respond to host commands in calibration mode.
3. Send the command C to initiate calibration sequence. The scale responds
4. <STX>CALIBRATE?<CR><LF>.
A-6
METTLER TOLEDO BC Shipping Scales Service Manual
30126862 | 02 | 12/2016
5. Send the command Y to continue with the calibration sequence, or send the command N to
abort the sequence. The scale responds <STX>UNLOAD SCALE- Y?<CR><LF>.
6. Remove any weight on the platter and send the command Y to continue. A stable zero reading
is taken, then the scale responds
7. <STX> ADD (Weight Value) (Weight Units) Y? <CR><LF> , where
(Weight Value) = weight amount (two or three digit number) to add to scale
(Weight Unit ) = LB or KG
8. Add the requested calibration weight to the scale, and then send the command Y to continue.
The scale responds
<STX> CAL DONE <CR><LF>
or
<STX> INCORRECT AMOUNT OF WEIGHT <CR><LF>.
A.3.
Protocols – Mettler-Toledo SICS Level 0
MT-SICS is a standard protocol used in Mettler-Toledo scales offered in Europe for RS232
communications to a host. The implementation of this protocol in the BC product line is described
below.
A.3.1.
Command Format
Commands sent to the scale are comprised of one or more characters of the ASCII character set.
The following are rules that must be followed.
A.3.2.
•
Commands are upper case.
•
The parameters of the command must be separated from one another and from the command
by a space character (ASCII 32 decimal).
•
The text characters must be within the ASCII character set from 32 decimal to 255 decimal.
•
Each command is terminated with a <CR><LF>.
•
Commands are only processed when the scale is in normal weighing mode. Any command
received while capturing zero at power-up, calibration or setup will be ignored until the
procedure is completed and any queued up commands will be executed then. This is based on
how both the Panther and the PG2002-S bases handle these conditions.
Response Format
All responses sent by the scale to acknowledge the received command have one of the following
formats:
30126862 | 02 | 12/2016
•
Response with weight value.
•
Response without weight value.

USB Virtual Serial Driver
This appendix covers
• Hardware
• Driver Installation
C.1.
The Virtual Serial Driver allows the BC scale to communicate serially over a USB cable
connection. This driver allows the scale to communicate serially with PC’s that do not have
a serial DB9 connection. The programming of the Virtual Serial capability is explained in
Chapter 4.
Hardware
The scale communication to the PC host is via a standard USB interface cable with an A connector
and a B connector. This cable will connect to a Series B type receptacle on the scale and the Series
A type receptacle on the PC.
An external USB/Serial adapter is not needed for communication.
Note: If a serial cable was supplied with the scale, please retain for future use in case the scale
software version needs to be updated.
The VIRTUAL DRIVER (USB) can communicate scale weight to the PC, but it cannot be used to
download new scale firmware. The scale serial port must be used to download scale firmware.
An external USB/Serial adapter (like Keyspan USA-19HS) utilizes the scale serial port and can be
used for PC’s that do not have a serial connection.
C.2.
Driver Installation
The software program required to enable the virtual serial capability of the BC scale is called the
Mettler Toledo Virtual Serial Port Installer, and it can be downloaded from the Mettler Toledo website
at:
•
www.mt.com/ind-bc-scale
Click on one of the BC models (BC-60), Go to the Download tab, select Virtual Driver, and
download to a folder on the local PC.
Once downloaded, open the setup.exe file on the PC.

Special Configuration
The following Price, Custom Message and Logo commands are designed to allow special
configuration of the graphical display screen only. The 0270 seven segment display does not
support these functions.
For the following commands to work, the scale must be able to communicate by MT SICS serial
protocol. For the PRICE command, the primary communication must be SICS protocol. For the
Custom Message update or the Logo update, the SICS protocol only needs to be set temporally. It is
best to write down the program parameters of the current set up before making any updates. You
can also set the CUSTOM Default in the scale to save the current communication set up. Refer to
chapter 4, section 13.
The SICS serial protocol can be used with RS232, Virtual USB (Serial by USB), Bluetooth (Serial by
Bluetooth), and Ethernet (Serial by Ethernet). The BC scale standard Bluetooth and Ethernet options
are already set up to communicate by the serial protocols.
To set the BC protocol to SICS, go to Home > Set-Up > Communication > Serial, and set the
following parameters
•
BAUD = 9600
•
Data Bit = 8
•
Parity = None
•
Stop = 1
•
Proto = SICS
If the scale is communicating by USB cable, you will also need to set Home > Set-Up >
Communication > USB = Virtual.
To send test messages, a terminal program like HyperTerminal can be used. Make sure the COM
port is correctly set:

Serial Communication
For the Price command to be effective, the scale needs to be set up for MT SICS protocol for both
weight and price communication. The host PC can send the price to the scale through the GSPMNY
command. The scale display will show the weight and Price as long as there is weight on the
platter. Once the scale reads zero again, the price is disabled.

Only one message can be displayed at a time. Message length should be no more than 30
characters including spaces.
Note: After the message has been sent, the scale may need to be rebooted to display it.
Refer to sections 4.9 and 4.9.5.
F.3.
Logo Command
The host PC can send a custom logo to the scale through SICS protocol, and the image will be
stored and displayed when the "Logo" option is enabled. Only one logo at a time can be stored and
displayed in the scale. The logo file has to be in a file.bmp format with a size of 5182 bytes. A 2
byte checksum will be added to the end of the file in the download process for a total of 5184
bytes.
Please contact Mettler-Toledo, LLC. for additional documentation on how to upload a specific logo.

Alibi Memory Retrieval Tool
The PC Tool will be used to output the Alibi data into a text format with no provision to store or
modify any portion of the data. The PC tool compares the checksum of each record in the Alibi
memory during the download process. If the checksum matches, then the data will be displayed by
the tool. The records with un-matched checksum will not be displayed. Instead the records will be
replaced by an '*'.
The tool will retrieve valid scale weight values from the scale memory for the last 30 days or more.
The Alibi Memory Retrieval tool can be downloaded from the MT website. See the download tab.
www.mt.com\ind-bc-scale.
I.1.
Set Up
To access the tool, the scale must be able to communicate by MT SICS serial protocol. It is best to
write down the program parameters of the current set up before making any updates. You can also
set the CUSTOM Default in the scale to save the current communication set up. Refer to chapter 4,
section 13.
The SICS serial protocol can be used with RS232, Virtual USB (Serial by USB), Bluetooth (Serial by
Bluetooth), and Ethernet (Serial by Ethernet). The BC scale standard Bluetooth and Ethernet options
are already set up to communicate by the serial protocols.
To set the BC protocol to SICS, go to Home > Set-Up > Communication > Serial, and set the
following parameters in the scale
BAUD = 9600
Data Bit = 8
Parity = None
Stop = 1
Proto = SICS
If the scale is communicating by USB cable, you will also need to set Home > Set-Up >
Communication > USB = Virtual. Note: BC Virtual Serial driver may be needed.
