2. DEVICE DESCRIPTION
2.1 Congratulations!
With the seca 684 electronic multi-functional scale, you
have purchased a highly precise and simultaneously
robust device.
For over 170 years, seca has used its experience in the
service of healthcare and, as a market leader, it has
always set standards in many countries of the world
with innovative developments in weighing and measur-
ing.
2.2 Intended use
Electronic multi-functional scale seca 684 is mainly
used in hospitals, medical practices and in-patient care
facilities in accordance with national regulations.
The scale is for conventional determination of weight
and establishment of general state of nutrition; it assists
the physician supervising treatment in making a diag-
nosis or deciding on a course of treatment.
To make an accurate diagnosis, however, other spe-
cific examinations have to be ordered by the physician
and their results taken into account, in addition to
determining a weight value.
2.3 Description of function
On some variants of this scale, the weight display can
be switched between kilograms (kg), pounds (lbs) and
stones (sts). Weight is determined within a few
seconds.
In addition to conventional determination of weight, the
seca 684 provides a function for determining body
mass index. To this end, height is entered on the key-
pad and the body mass index associated with the
weight value is calculated automatically. Length meas-
uring devices from the seca 360° wireless system can
transmit height to the seca 684 wirelessly.

60 •
Via the seca 360° wireless wireless network, measur-
ing results can be transmitted wirelessly to a seca wire-
less printer or to a PC equipped with seca analytics
PC software and the seca USB wireless adapter.
The seca 684 can be moved on casters.
Use the scale only for the purpose named in the sec-
tion entitled "Intended use" on page 59.
2.4 User qualification
Assembly Devices that are shipped partially assembled may only
be mounted by sufficiently qualified persons such as
specialist dealers, hospital technicians or seca service
technicians.
Operation The device may only be operated by healthcare
professionals.

tion. If you fail to take note of this information,
serious irreversible or fatal injuries will occur.
WARNING!
Used to identify an extremely hazardous situa-
tion. If you fail to take note of this information,
serious irreversible or fatal injuries may result.
CAUTION!
Used to identify a hazardous situation. If you fail
to take note of this information, minor to moder-
ate injuries may result.
ATTENTION!
Used to identify possible incorrect usage of the
device. If you fail to take note of this information,
you may damage the device, or the measured
results may be incorrect.
NOTE:
Includes additional information about use of the
device.
3.2 Basic safety instructions
Handling the instrument • Please take note of the information in these instruc-
tions for use.
• Keep the instructions for use in a safe place. The
instructions for use are a component of the device
and must be available at all times.
DANGER!
Risk of explosion
Do not use the device in an environment in
which one of the following gases has accumu-
lated:
–oxygen
– flammable anesthetics
– other flammable substances/air mixtures

62 •
CAUTION!
Patient hazard, damage to device
• Additional devices which are connected to
electrical medical devices must provide evi-
dence of compliance with the relevant IEC or
ISO standards (e.g. IEC 60950 for data-
processing devices). Furthermore, all configu-
rations must comply with the requirements of
standards for medical systems (see IEC
60601-1-1 or Section 16 of the 3rd edition of
IEC 60601-1 respectively). Anyone connect-
ing additional devices to electrical medical
devices is considered a system configurer
and is therefore responsible for ensuring that
the system complies with the requirements of
standards for systems. Your attention is
drawn to the fact that local laws take prece-
dence over the above-mentioned require-
ments of standards. In the event of any
queries, please contact your local specialist
dealer or Technical Service.
• Have servicing carried out regularly as
described in the relevant section of this docu-
ment.
• Technical modifications may not be made to
the device. The device does not contain any
parts for servicing by the user. Only have serv-
icing and repairs performed by an authorized
seca service partner. You can find service
partners in your area at www.seca.com or by
sending an e-mail to [email protected].
• Only use original seca accessories and spare
parts, otherwise seca will not grant any war-
ranty.
CAUTION!
Patient hazard, malfunction
• Keep other electrical medical devices, e.g.
high-frequency surgical devices, a minimum
distance of approx. 1 meter away to prevent
incorrect measurements or wireless transmis-
sion interference.
• Keep HF devices such as cell phones a mini-
mum distance of approx. 1 meter away to
prevent incorrect measurements or wireless
transmission interference.

• 63
English
• The actual transmission output of HF equip-
ment may require minimum distances of more
than 1 meter. Details can be found at
www.seca.com.
Preventing electric
shock WARNING!
Electric shock
• Set up the device so that the power supply
socket is easy to reach and the device can be
disconnected from the power supply quickly.
• Ensure that your local power supply matches
the information on the power supply unit.
• Do not touch the power supply unit with wet
hands.
• Do not use extension cables or power strips.
• Ensure that the power cable is not pinched or
damaged by a sharp edge.
• Do not operate the device above an altitude of
3000 m.
Avoiding infections
WARNING!
Risk of infection
• Hygienically reprocess the scales regularly as
described in the respective section in this
document.
• Make sure that the patient has no infectious
diseases.
• Make sure that the patient has no open
wounds or infectious skin alterations, which
may come into contact with the device.
Avoiding injuries
WARNING!
Risk of falling
• Ensure that the device is positioned firmly and
level.
• Route the mains cable so that there is no risk
of tripping for the patient or user.
• The device is not designed as a standing aid.
Assist people with limited motor skills when
they are getting up, e.g. from a wheelchair.

64 •
• Make sure that the patient does not step onto
the weighing platform directly at the edges.
• Make sure that the patient steps onto the
weighing platform slowly and securely.
WARNING!
Danger of slipping
• Ensure that the weighing platform is dry
before the patient steps onto it.
• Ensure that the patients feet are dry before he
or she steps onto the weighing platform.
• Make sure that the patient steps onto the
weighing platform slowly and securely.
Preventing device
damage ATTENTION!
Damage to device
• Ensure that no liquids enter the device. They
can damage the electronics.
• Switch off the device before disconnecting the
power supply unit from the mains socket.
• Disconnect the power supply unit from the
mains socket if you intend to not use the
device for a longer period of time. Only this
way it can be ensured that the device is cur-
rentless.
• Make sure not to drop the device.
• Do not expose the device to any impacts or
vibrations.
• Perform function controls regularly as
described in the relevant section in this docu-
ment. Do not operate the device if it is dam-
aged or not working properly.
• Ensure that there is no heat source in the
immediate vicinity. Do not expose to direct
sunlight. The excessive temperature could
damage the electronics.
• Avoid rapid temperature fluctuations. When
the device is transported so that a tempera-
ture difference of more than 20 °C occurs, it
must stay turned off for at least 2 hours before
it can be turned on again. Otherwise, conden-
sation water will form which can damage the
electronics.
