1. Congratulations!
By purchasing the seca 954 electronic
chair scale, you have acquired a highly-accurate and sturdy piece of equipment.
seca has been putting its experience at
the service of health for over 150 years
now, and as market leader in many countries of the world, is always setting new
standards with its innovative developments for weighing and measuring.
In accordance with national regulations, the
seca 954 wheelchair scale with standing
aid is used primarily in hospitals, doctors’
surgeries and in-patient nursing facilities.
The weight display can be switched between kilogrammes (kg), pounds (lbs) and
stones (sts). Weight is determined within a
few seconds.
The seca 954 can be moved on castors
and its low power consumption combined
with its rechargeable batteries mean it will
provide long, mobile service.
The seca 954 chair scale is made for people who are not especially steady on their
feet. To give you a safe feeling while
weighing, the chair scale has a solid tubular frame and a firmly bolted seat. The freerunning casters make the scale very easy
to move. The wheel-locking lever, together
with the swiveling armrests and foot supports, makes it easier to sit in safety.
The scale is of a very sturdy construction
and will give you long and loyal service. It
is easy to operate and the large display is
easy to read.
2. Safety
Before using the new scale, please take a little time to read the following safety instructions.
• Use only the type of battery stated (see

3. Before you start…
Unpacking
The scope of supply includes:
• Chair scale comes complete or partly assembled
• 1 seca mains unit
• 1 set of operating instructions
Assembling
This chair scale is available either fully or partly assembled. To assemble the partly-assembled model, please proceed as follows:
– locate the handles on the journals provided and bolt in place using the two
M6 x 16 bolts, following the diagrams.
– Thread the mounting bolts for the display unit through the bores provided in
the handles and screw the display tightly in place using two M4 nuts.
– Attach the weighing cell cable using the
enclosed plastic cable clip by pushing
this into the bores on the handles.
Model 954
GB 15
– Fit the seat to the frame using the four
self-tapping plastic screws. Check that
the seat is screwed tightly to the frame
with no play at all.
– Push the hinge bolts for the armrests
through the hinge bushes on the seat
frame. Put on the washer and cap nut
(M10) and screw them tight.
Power supply
The scale is powered by a mains unit and by rechargeable batteries.
Connecting the rechargeable battery pack
– Open the battery compartment in the
base of the display housing.
– Connect the plug contacts to the rechargeable battery pack located in the
battery compartment.
– Close the lid of the battery compartment again.
The LC display and the evaluation electronics have a low power consumption – 1,000
weighing operations can be performed with a fully charged battery.
Once battery voltage is no longer adequate, the battery symbol
first appears in
the display to indicate that battery power is dropping.
If the batteries are not charged, battery voltage will ultimately not be adequate for errorfree measuring. In this case, bAtt appears in the display and weighing is no longer possible.
16
The rechargeable batteries are charged by
the mains unit supplied. For this purpose,
the mains unit needs to be connected to
the mains for at least 24 hours.

Other controls
The armrests on the chair scale can be swivelled backwards independently. This is useful
because it makes it easier for the person being weighed to sit down.
– Ensure that you do not trap any part of
the body or pieces of clothing when
folding the rests down.
– The rear casters can be locked if you
push down the two locking levers on
the casters. This device should be used
when the patient is sitting down on the
scale or getting up from it.
Locking lever
– Once the person who is to be weighed
is seated, the foot-rests are pulled out
and tilted downwards. The patient can
now place his or her feet on the footrests.
Correct weighing
– Press the Start key.
se(a, 8.8.8.8.8. and 0.0 appear consecutively in the display. The scale is then
automatically set to zero and ready to
use.
– If necessary, switch the weight display
(see page 19).
– Get the patient to sit on the scale.
– The patient’s weight can only be determined once he or she is no longer in
contact with the floor. Be sure, therefore, that the patient’s feet are on the
foot rest throughout the weighing operation.
18
– Read the weighing result off the digital
display.
– If a load greater than 200 kg or 440 lbs
is placed on the scale, St0P appears in
the display.
– To switch off the scale, press the Start
key again.
Switching the weight display
The weight display can be switched between kilogrammes (kg) and pounds (lbs) or between kilogrammes (kg) and stones (sts).
– Switch on the scale using the green
Start key. Weight is initially displayed in
the last setting selected.
– To switch the weight display between
kilogrammes and pounds, press the kg/
lbs/sts key.
– The kg or lbs display lights up.
– To switch weight display between
pounds and stones, hold down the
kg/lbs/sts key for approx. 2 seconds.
The lbs or sts display lights up.
Automatic switch-off/economy mode
The scale switches off automatically after 5 minutes.
Taring weight display (TARE)
The Tare function is very useful if an additional weight (a blanket, for example) is to be ignored for weighing purposes.
Proceed as follows:
– Press the green Start key.
– First place the additional weight (e.g. a
blanket) on the scale and activate the
Tare function by pressing and holding
the HOLD/TARE key.
The display is reset to zero. 0.0 appears
in the display. The note “NET” appears.
– Now put the patient and the additional
weight on the scale.
The scales calculate the patient’s
weight without the additional weight.
You can now perform as many weighing operations as you like.
Model 954
GB 19
– Hold the key down again to deactivate
the Tare function; the scale is then back
in normal weighing mode and the tare
value has been erased.
– The tare value is likewise erased by the
scale being switched off.
Store weight value (HOLD)
You can also continue displaying the weight determined once the load has been removed.
This makes it possible to look after a patient first, before having to note the weight:
– Press the HOLD/TARE key whilst the
load is on the scale.
“HOLD” appears in the digital display. The
value is stored until the scale switches off
automatically.
– The HOLD function can be switched off
by pressing the HOLD key again.
0.0 appears in the display if the scale has
no load on it, otherwise the current weight.
The “HOLD“ display vanishes.
Note:
The HOLD and TARE functions can also be used simultaneously.
Body Mass Index (BMI)
Body Mass Index puts height and weight in relationship to one another, providing more
accurate information than ideal Broca weight, for example. A tolerance range is given
which is considered ideal for health. The Body Mass Index applies only to adults: these
values are not relevant to children and young people.
– Press the Start key.
se(a, 8.8.8.8.8. and 0.0 appear consecutively in the display. The scale is
then automatically set to zero and ready
for operation.
– Press the FUNC key.
On the display, you will see the last
height entered.
– You can use the arrow keys to adjust
the value in increments according to the
graduations displayed.
– Once the correct value is set, press the
FUNC key again. The BMI function is
now activated.
– Get the patient to sit on the scale.
– Read off the BMI on the digital display
and compare it with the categories on
page 21.
20
– Press an arrow key if you would like to
see the weight briefly.
– To return to normal weighing mode,
press the FUNC key.
– To switch off the scale, press the Start
key again.
Evaluating Body Mass Index:
Compare the value determined with the categories shown below.
• BMI below 18:
Warning, this patient weighs too little. There could be a tendency to anorexia. An increase in weight is recommended to improve well-being and performance. If in doubt,
consult a specialist.
• BMI between 18 and 20:
Patient is at lower weight limit. If he feels well and is completely healthy, his weight can
stay as it is.
• BMI between 20 and 25:
The patient is of a normal weight. He can stay as he his.
• BMI between 25 and 30:
The patient is slightly to moderately overweight. He should cut his weight if he is already ill (e.g. diabetes, hypertension, gout, fat metabolism disorders).
• BMI over 30:
Weight reduction is essential. Metabolism, cardiovascular system and bones are all under strain. A consistent diet, plenty of movement and behavioural training are all recommended. If in doubt, consult a specialist.
5. Cleaning
Clean the seat and the housing as required using a domestic cleaning agent or commercially-available disinfectant. Follow the manufacturer’s instructions.
Under no circumstances use abrasive or acid cleaners, white spirit, benzene or the like for
cleaning. Such substances can damage the high-quality surfaces.

6. What do I do if…
… no weight display comes on?
– Is the scale switched on?
– Check the mains connection and the connection of the battery pack.
– Switch the scale off for a few seconds. This can be done by opening the plug connected to the rechargeable battery block and unplugging the mains supply from the scale.
… 0.0 does not appear before weighing?
– Switch off the scale with the Start key and start the scale again – there must not be
any load on the scale – and only its feet should be in contact with the floor.
… one segment is illuminated constantly or not at all?
– The relevant segment has a fault. Inform Servicing.
… the display shows
?
– Battery voltage is dropping. Charge the rechargeable batteries in the next few days.
… batt appears in the display?
– The rechargeable battery is so severely discharged that weighing is no longer possible.
Recharge the battery.
… St0p appears in the display?
– Maximum load has been exceeded.
… the display flashes?
– If you have just activated the Hold or Tare function, please wait until the scale has detected a steady weight value. The display will then stop flashing.
– If there has been no activation of a function beforehand, remove the load from the scale
and wait until 0.0 is displayed, then weigh again.
… the display
appears?
– The ambient temperature of the scale is too high or too low. Place the scale in an
ambient temperature between +10 °C and +40 °C. Wait about 15 minutes for the
scale to adapt to the ambient temperature and then weigh again.
… the display E and a number appear?
– Switch off the scale with the Start key and start the scale again. The scale will then
work normally again.
If this is not the case, disconnect the power supply by briefly removing the batteries. If
this measure is equally unsuccessful, inform the Service department.
7. Servicing
Your seca scale leaves the factory with an accuracy greater than ± 0.1 %. To ensure that
this accuracy is maintained, the product must be carefully set up and regularly maintained.
Depending on the frequency of use, we recommend servicing every 3 to 5 years. Please
ensure that a qualified service agent is used. If in doubt, contact seca Customer Service for
further information.

10. Disposal
Rechargeable batteries
Disposing of the scale
Do not throw old rechargeable batteries
into the domestic refuse! Ensure that rechargeable batteries are properly disposed of at local collection points.
If the scale can no longer be used, the responsible waste disposal association will
be glad to advise you on the measures
necessary to dispose of it properly.
11. Warranty
A two-year warranty from date of delivery
applies to defects attributable to poor materials or workmanship. All moveable parts
- batteries, cables, mains units, rechargeable batteries etc. - are excluded. Defects
which come under warranty will be made
good for the customer at no charge on
production of the receipt. No further
claims can be entertained. The costs of
transport in both directions will be borne
by the customer should the equipment be
located anywhere other than the customer’s premises. In the event of transport
damage, claims under warranty can be
honoured only if the complete original
packaging was used for any transport and
the scale secured and attached in that
packaging just as it was when originally
packed. All the packaging should therefore be retained.
A claim under warranty will not be honoured if the equipment is opened by persons not expressly authorised by seca to
do so.
We would ask our customers abroad to
contact their local sales agent in the event
of a warranty matter.
QuickMedical is an authorized distributor for seca.
