1. DEVICE DESCRIPTION
1.1 Intended use
The seca 644 electronic scale with standing aid is
mainly used in hospitals, doctors' surgeries 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.
1.2 Description of function
On some variants of this scale, the weight display can
be switched between kilograms (kg), pounds (lbs) and
stones (st). Weight is determined within a few seconds.
In addition to conventional determination of weight, the
seca 644 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 644 wirelessly.
Via the seca 360° wireless network, measuring results
can be transmitted wirelessly to a seca wireless printer
or to a PC equipped with seca analytics PC software
and the seca USB wireless adapter.
The seca 644 can be moved on casters.
Use the scale only for the purpose named in the sec-
tion entitled "Intended use" on page 63.

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 (weight: kilogrammes, length: metres)
only. Some devices offer the ability to display
test results in other units. This is only an additio-
nal function.
►Use the results exclusively in SI units.
►The use of measurement results in non-SI
units is the sole responsibility of the user.
