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.
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
2.2.4.1.2. Graphical Display
Refer to
for a table of regions and corresponding GEO codes.
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. For
best accuracy, the scale should be calibrated on-site by a trained technician using certified
weights.
If the initial boot screen (Figure 2-6) is displayed, the scale will prompt for the entry of a Geo
code, and selections for language, unit selection and the type of manifest software the scale
will communicate with.

2.3. 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.
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).
• 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 needs to be matched to the scale capacity and increment
size. So changing the 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.
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.

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.
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.
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:
Plug in USB cable to an energized PC. Power can also be supplied
from a powered USB hub between the scale and PC.
Plug in USB cable to the power adapter and then plug the power
adapter into an AC outlet.
* The Ethernet and Bluetooth options are not currently available.
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
USB
Other (RS232, Ethernet, Bluetooth)
The BC goes through a power-up sequence each time power is applied. The scale performs a
diagnostic test on its ROM and RAM, and then proceeds to the normal operating mode. The powerup 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. Software
number for the standard BC model is 30099478, version 00.00.01.
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:

Unplug the power adapter from AC outlet.
3.2. Keypad and Display
The BC scale includes a monochrome graphical display 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.
A Basic 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.
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).

The R1 / R2 / R3 icon will indicate the weight range on Multi-Range models. Range indication is
not needed with Multi-Interval models that have auto-ranging capability.
3.2.1. Display
The BC scale graphical display has a monochrome screen with a resolution of 240 x 160 pixels.
Each weight digit is 12 mm high standard, with option for 21mm high. The BC’s status symbols

3.3. Keys and Navigation
The BC keypad contains a navigation key for easy scrolling and selection of the softkeys, as well as
entering of parameter options.
3.3.1. Navigation Keys
Four navigation keys (Figure 3-3) allow the cursor to be moved UP, DOWN, RIGHT, and LEFT, to
select softkeys and parameters on the graphical display. The position of the cursor is indicated by
the softkey box (outline) being shown in bold (e.g., Figure 3-5). The central ENTER key allows
selection of the softkey.

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. 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 (XREF).

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.

The BC shipping scale is designed to be virtually error-free and reliable. If problems do occur, do
not attempt to repair the scale before you have determined the source of the problem. Record as
much information as possible about what has happened including any messages and physical
responses. The following troubleshooting information may help to determine the cause of the
problem.

ALWAYS REMOVE ALL POWER BEFORE SERVICING ANY EQUIPMENT. METTLER-TOLEDO
RECOMMENDS THAT ONLY QUALIFIED TECHNICIANS OPEN THE UNIT UP FOR MAINTENANCE
AND REPAIR. IF YOU MUST OPEN THE BC SCALE, READ THIS SECTION CAREFULLY TO AVOID
DAMAGE TO THE INTERNAL COMPONENTS.
5.1.1. Error Codes
The BC scale keeps a log of the five most recent errors. This information can be viewed by pressing
the UP arrow for 5 seconds, then navigating to

The BC scale can have either of two power sources, depending on its mode of communication:
* Ethernet and Bluetooth options not currently available.
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.

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.
5. If there is still no activity, consult a METTLER TOLEDO technician. The PCB may be damaged.
5.1.3. Blank Display
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.
Figure 5-1: Green PCB Status Light Illuminated
• 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.

5.1.6. Serial Communication Test with PC
This test does not apply if PC communication is via USB.
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.
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.
