2. DESCRIPTION OF DEVICE
2.1 Congratulations!
With the seca 954 electronic scale, you have just
purchased a highly precise and simultaneously robust
weighing instrument.
seca has put its experience at the service of health care
for over 170 years and as a market leader in many
countries, is constantly setting new standards with its
innovative developments for weighing and measure-
ment.
2.2 Intended use
The seca 954 electronic scale is mainly used at hospi-
tals, medical practices and inpatient 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 speci-
fic examinations have to be ordered by the physician
and their results taken into account in addition to deter-
mining a weight value.
Some versions of these scales allow you to switch the
weight display between kilos (kg), pounds (lbs) and
stones (sts). The result of weighing is available within a
few seconds.
Besides conventional weight measurement the
seca 954 also features a function to calculate the body
mass index. The keypad is used to enter the height,
and this is followed by automatic calculation of the
body mass index from the weighing value. Height
measuring instruments from the seca 360° wireless
system can transmit the body size wirelessly to the
seca 954.
Via the wireless network, seca 360° wireless measur-
ing instruments can be connected wirelessly to a seca
wireless printer or to a PC equipped with
seca analytics PC software and the secaUSB wireless
adapter.

50 •
The seca 954 is provided with rollers to allow it to be
moved about and thanks to its low power consump-
tion, it will offer hours of battery operation for mobile
applications.
The seca 954 is not intended for the transport of
people or objects. Use the scale only for the purpose
named in this section.

English
6. OPERATION
6.1 Weighing
CAUTION!
Patients can be injured if they fall
People with limited mobility can fall if they try to
sit down on the scale.
– Make sure that the scale’s wheel brakes are
set.
–Assistpeoplewithlimited mobility when they
are sitting down.
–Leavethefootrestsfolded up and pushed in
until the patient is sitting on the scale.
CAUTION!
Patients can be injured if their limbs get pinched
The patient’s hands and arms can be pinched
between the seat and the lower frame or
between the seat and the armrests.
– Make sure that the patient’s hands and arms
are on the armrests or in his lap during the
weighing process.
ATTENTION!
Incorrect measurement due to force shunts
If accessories (e.g. the power pack pouch) or
articles of clothing get caught between the seat
and the frame, the weight will not be measured
correctly.
If the patient’s feet are not on the footrests, the
weight will not be measured correctly.
– Make sure that there are no accessories or
articles of clothing between the seat and
frame.
–Makesurethatthearmrestsarefoldeddown
during the weighing process.
–Makesurethatthepatient’s feet are on the
footrests during the weighing process.
Switching on the scale Press the Start key.
The display will read se[A and then quickly run
through all elements of the display.
The scales are ready for operation when the display
reads 0.00.
If the device is being operated with a power supply
unit, the symbol will appear in the display.

64 •
Start weighing 1. Set the wheel brakes of the rear transport rollers.
2. Fold the armrest toward the back in order to make
it easier for the patient to sit down.
3. Make sure that the scale has no load.
4. Switch the scale on.
5. Ask the patient to sit down on the scale.
6. Fold the footrests down.
7. Pull the footrests down until they stop.
8. Ask the patient to put his feet on the footrests.
9. Fold the armrests down.
10. Read the measurement result.
