2. DEVICE DESCRIPTION
2.1 Congratulations!
With the seca 676 electronic platform 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 platform scale seca 676 is mainly used in
hospitals, medical practices and in-patient care facili-
ties 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 676 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 676 wirelessly.

54 •
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 676 can be moved on casters.
Use the scale only for the purpose named in the sec-
tion entitled "Intended use" on page 53.
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.

Handling measuring
results WARNING!
Patient hazard
This device is no diagnostic device. It simply
assists the treating physician in establishing a
diagnosis.
– In order to make a precise diagnosis and
initiate therapeutic measures, besides
determination of the weight, further targeted
examinations must be set up by the
physician, and their results must be
considered.
– The responsibility for diagnosis and treatment
lies with the treating physician.
CAUTION!
Patient hazard
In order to avoid misinterpretations, test results
for medical use must be displayed and used in
SI units only. Some devices offer the ability to
display test results in other units. This is only an
additional function.
– Use the results exclusively in SI units.
– The use of measurement results in non-SI
units is the sole responsibility of the user.
ATTENTION!
Loss of data
• Before you save measurements aquired with
this device and process them for further use
(e.g. in the PC software seca analytics or in a
hospital information system), make sure the
measurement values are plausible.
• If measurement values are transmitted to the
seca analytics PC software or a hospital
information system, make sure prior to further
use that the measurement values are plausi-
ble and are assigned to the correct patient.
