Introduction
User manual 22013181B 05/08
1.3 Putting into operation
1.3.1 Selecting or changing the location
The correct location is crucial to the accuracy of the weighing results!
Major geographical
location changes
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.
➜ Select a stable, vibration-free and if possible a horizontal location.
The ground must be able to safely bear the weight of the fully loaded scale.
Observe the following environmental conditions:
• No direct sunlight
• No strong drafts
• No excessive temperature fluctuations
Aligning the scale
Only scales that have been aligned precisely horizontally provide accurate weighing
results.
➜ Turn the adjustable feet of the scale until the spirit level’s air bubble is inside the
inner circle.

1.3.2 Connecting the power supply
CAUTION!
Before connecting the scale to the mains, check whether the voltage value printed on
the rating plate corresponds with the local mains voltage.
▲ Never connect the device if the voltage value printed on the rating plate is different
to the local mains voltage.
➜ Plug the mains plug into the socket.
After connection, the device performs a self-test. When the zero display appears,
the device is ready to weigh.
➜ Calibrate the device in order to obtain the greatest possible precision, see
Section 4.3.2.
Note 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.
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.

5.1 SICS interface commands
The compact scales BBA432 / BBK432 support the command set MT-SICS (METTLER
TOLEDO Standard Interface Command Set). With SICS commands, it is possible to
configure, query and operate the scales from a PC. SICS commands are divided up
into various levels.
5.1.1 Available SICS commands
In the case of Levels 0 and 1, these are commands which, if implemented, will
function identically with all METTLER TOLEDO scales or weighing terminals.
In addition there are also further interface commands which apply either to the entire
product series or to the particular application level. This and further information on the
MT-SICS command set may be found in the MT-SICS Manual (Order Number 22 011
459 or at www.mt.com) or be obtained by request from your METTLER TOLEDO
customer service representative.
Command Meaning
LEVEL 0 @ Reset the scale
I0 Inquiry of all available SICS commands
I1 Inquiry of SICS level and SICS versions
I2 Inquiry of scale data
I3 Inquiry of scale software version
I4 Inquiry of serial number
I6 Inquiry of weighing parameters
S Send stable weight value
SI Send weight value immediately
SIR Send weight value repeatedly
Z Zero the scale
ZI Zero immediately
LEVEL 1 D Write text into display
DW Weight display
K Keyboard check
SR Send and repeat stable weight value

TA Tare value
TAC Clear tare
TI Tare immediately

5.1.2 Requirements for communication between scale and PC
• The scale must be connected to the RS232, RS485, USB or Ethernet interface of a
PC with a suitable cable.
• The interface of the scale must be set to "Dialog" mode, see Section 4.6.1.
• A terminal progam must be available on the PC, e.g. HyperTerminal.
• The communication parameters baud rate and parity must be set in the terminal
program and on the scale to the same values, see Section 4.6.3.
5.1.3 Notes on network operation via the optional interface RS422/485
Up to 32 scales can be networked with the optional RS422/485 interface. In network
operation, the scales must be addressed from the computer before commands can be
sent and weighing results received.

8.1 Safety checks
The compact scales of the series BBA432 / BBK432 have been checked by accredited
testing institutions. They have passed the safety checks listed below and carry the relevant test symbols. Production is subject to production monitoring by the inspection
offices.
8.2 FCC
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to both Part 15 of the FCC Rules and the radio interference regulations of the Canadian Department of Communications. These limits are designed to
provide a reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the user
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case
the user will be required to correct the interference at his own expense.
Cet appareil a été testé et s’est avéré conforme aux limites prévues pour les appareils
numériques de class A et à la partie 15 des règlements FCC et à la réglementation des
radio-Interférences du Canadian Department of Communications. Ces limites sont
destinées à fournir une protection adéquate contre les interférences néfastes lorsque
l’appareil est utilisé dans un environnement commercial. Cet appareil génère, utilize
et peut radier une énergie à fréquence radioélectrique; il est en outre susceptible
d’engendrer des interférences avec les communications radio, s’il n’est pas installé et
utilisé conformément aux instructions du mode d’emploi. L’utilisation de cet appareil
dans les zones résidentielles peut causer interférences néfastes, auquel cas
l’exploitant sera amené à prendre les dispositions utiles pour palier aux interférence à
ses propres frais.
