2. DEVICE DESCRIPTION
2.1 Congratulations!
In purchasing the seca 644 electronic scale with stand-
ing aid, you have acquired a high-precision yet 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
measuring.
2.2 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.
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 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.
