2. DESCRIPTION OF DEVICE
2.1 Congratulations!
With the seca 955 electronic scale, you have just pur-
chased 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 955 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 spe-
cific examinations have to be ordered by the physician
and their results taken into account in addition to deter-
mining a weight value.
Besides conventional weight measurement the
seca 955 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.
The seca 955 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 955 is not intended for the transport of peo-
ple or objects. Use the scale only for the purpose
named in this section.

3. SAFETY INFORMATION
3.1 Basic safety precautions
Handling the instrument • Please take note of the information in this user
manual.
• Keep the user manual with the declaration of
conformity in a safe place.
• Make sure that the scales are positioned securely on
a flat and stable surface.
• Make sure before each use that the wheel brakes
are working.
• Secure the scale against unintentional rolling away.
Set the wheel brakes.
• Do not transport any people or objects with the
scale.
• Move the scale only with released wheel brakes.
• Make sure you do not drop the scales. Protect the
scales from violent impacts.
• If you operate the scale with a battery power pack,
make sure that when you route the power cable, no
one can trip over it.
• If you operate the scale with a battery power pack,
make sure that when you route the power cable, it
cannot be crushed or come into contact with hot
objects.
• Have the scales serviced regularly (see "Mainte-
nance/Recalibration" on page 28).
• Make sure that maintenance and repair are only car-
ried out by an authorised service partner. You can
find your local service partner at www.seca.com or
just send an e-mail to [email protected].
• Make sure you only use genuine seca accessories
and spare parts. Otherwise the warranty provided
by seca will become null and void.
• Make sure RF equipment such as mobile phones is
kept at a minimum distance of approx. 1 metre to
prevent incorrect measurements or interference with
radio transmission.

6.2 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.
– Assist people with limited mobility when they
are sitting down.
– Leave the footrests folded 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.
– Make sure that the armrests are folded down
during the weighing process.
– Make sure that the patient’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.

Tare off additional
weight (TARE)
You can use the TARE function to prevent the weighing
result from being affected by an additional weight (e.g.
a towel or pad on the weighing surface).
ATTENTION!
Incorrect measurement with force shunt
If an additional weight (e.g. large towel) is in
contact with the surface on which the scales
are standing, the weight will not be measured
correctly.
– Make sure that any additional weight is only
placed on the weighing surface of the scales.
1. Switch the scale on.
2. Place the additional weight on the scales.
3. Hold down the arrow key (hold/tare) until "NET"
appears in the display.
4. Wait until the display stops flashing and is replaced
by 0.00.
5. Weigh the patient as described in section “Start
weighing”.
6. Read off the measured result.
The additional weight has been automatically
deducted.
7. To disable the TARE function, press the arrow key
(hold/tare) until "NET" no longer appears in the
display or switch off the scales.
NOTE:
The maximum weight that can be displayed is
reduced by the weight of the objects already
placed on the scales.
Continuous display of
measured
result (HOLD)
If you activate the HOLD function, the weighing value
will continue to be displayed after the load has been
removed. This allows you to attend to the patient
before noting down the weight.
1. Check that there is no load on the scales.
2. Switch the scale on.
3. Weigh the patient as described in section “Start
weighing”.
4. Briefly press the arrow key (hold/tare).

The display will flash until a stable weight is meas-
ured. The weighing value will then be displayed
continuously. The symbol (non-calibratable func-
tion) and the message "HOLD" will be displayed.
5. To disable the HOLD function, briefly press the ar-
row key (hold/tare).
The symbol and the message "HOLD" will no
longer be displayed.
NOTE:
If the auto hold function is activated, the weight
value is displayed permanently automatically
until the scale switches itself off or is switched
off (see "Activate Autohold function (Ahold)" on
page 24).
Determine and evaluate
body mass index (BMI)
The body mass index compares height and weight, so
resulting in more accurate figures than with Broca's for-
mula for ideal weight. It includes a tolerance range
which is considered ideal in health terms.
1. Check that there is no load on the scales.
2. Switch the scale on.
3. Briefly press the arrow key (bmi/menu).
The message "BMI" appears.
Arrows can be seen flashing in the display.
The height last entered is displayed.
4. You can either accept this height or select another
value using the arrow keys.
5. Confirm your selection with the Enter key.
6. Weigh the patient as described in section “Start
weighing”.
7. Read off the BMI and compare it with the
categories given below.
8. To disable the BMI function, briefly press the Enter
key.

BMI Evaluation
Under 18.5
The patient is underweight. There might be a tendency to
anorexia. It is advisable that the patient puts on weight to
improve well-being and performance. If in doubt, a medical
specialist should be consulted.
