1. Congratulations!
By purchasing the seca 634 electronic
platform 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 coun-
tries of the world, is always setting new
standards with its innovative develop-
ments for weighing and measuring.
In accordance with national regulations, the
seca 634 platform scale is used primarily
in hospitals, doctors’ surgeries and in-pa-
tient nursing facilities.
The weight display can be switched be-
tween kilogrammes (kg), pounds (lbs) and
stones (sts). Weight is determined within a
few seconds.
In addition to the conventional determina-
tion of weight, the seca 634 also has a
function for determining body mass index.
For this purpose, height is entered on the
keypad and the body mass index associ-
ated with the weight value is output.
You can use the pre-Tare function to
record the weights of, e.g. three types of
chair. This weight is automatically deduct-
ed in the weighing operation.
The high capacity of this scale and its fine
display graduations make it particularly
suitable for monitoring the weight of adi-
pose patients.
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 instruc-
tions.
• Follow the safety instructions in the in-
struction manual.
• Keep the operating manual and the
declaration of conformity contained
therein in a safe place.
•Do not drop the scale or subject it to vi-
olent shocks.
• Place the scale carefully in its position
for use.
• Avoid pulling hard on the connecting
cable to the display unit.
•Secure the scale so that it does not fall
over when stored in the upright position.
•When using the scale with a mains unit,
ensure that the supply cable is routed in
such a way as to exclude any type of
tripping hazard.
•The cable between the weighing plat-
form and the case must be laid so that it
does not present a tripping hazard.
•Have scale serviced on a regular basis
(see “Servicing” on page 24).
• Have repairs carried out exclusively by
authorised persons.

Taring weight display (TARE)
The Tare function is very useful if an additional weight, e.g. that of a chair, is to be ignored
for weighing purposes.
Proceed as follows:
– Press the green Start key.
–First place the additional weight (e.g.
the chair) on the scale and activate the
Tare function by pressing and holding
the HOLD/TARE key.
The display is reset to zero, 0.0 flashes
in the display until weight is detected to
be stable. Only then is the Tare function
fully activated. The note “NET” appears.
–Now place the patient on the scale. The
patient may remain seated.
The scale determines the weight of the
additional load. You can now perform
as many weighing operations as you
like.
–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 con-
secutively in the display. The scale is
then automatically set to zero and ready
for operation.
– Press the FUNC key.
The last function used appears in the
display.
–Use the arrow keys to select the BMI
function, FU 1. Activate the function by
pressing the FUNC key again.
An arrow on the left-hand side of the
display indicates which memory is set.
–Use the arrow keys to select the memo-
ry position under which you wish to re-
cord – or under which you have already
recorded – the patient’s height.
–Press the FUNC key again. The pati-
ent’s recorded height will then appear
on the display.
–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.
– Step on the scale and keep still.
–Read off the BMI on the digital display
and compare it with the categories on
page 21.
–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 in-
crease 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 al-
ready ill (e.g. diabetes, hypertension, gout, fat metabolism disorders).
• BMI over 30:
Weight reduction is essential. Metabolism, cardiovascular system and bones are all un-
der strain. A consistent diet, plenty of movement and behavioural training are all rec-
ommended. If in doubt, consult a specialist.
Weighing with pre-Tare
If the pre-Tare function is activated, a stored weight value is deducted from the currently
measured weight. This function is useful, for example, if the weight of a chair is not to be
displayed.
Three different tare weights (chair weights) can be stored.
– Press the Start key.
se(a, 8.8.8.8.8. and 0.0 appear con-
secutively in the display. The scale is
then automatically set to zero and ready
for operation.
– Press the FUNC key.
The last function used appears in the
display.
–Use the arrow keys to select the pre-
Tare function FU 3.
–Activate the function by pressing the
FUNC key again.
An arrow on the left-hand side of the
display indicates which memory is set.
–Use the arrow keys to select the desired
memory for storing the additional
weight or where a weight may already
be stored.
–Press the FUNC key again. In the dis-
play you will see the tare value from the
memory.

–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 pre-Tare function
is now activated.
–Place the chair associated with the
stored tare value on the scale.
–Now place the patient on the scale. The
patient may remain seated.

press the FUNC key.
–To switch off the scale, press the Start
key again.
Tip:
Note the weight on your chairs.
Setting damping
Damping is useful for reducing weight determination malfunctions (due to patient move-
ments, for example). The stronger the damping, the more slowly the weight display re-
acts. You can set damping to suit requirements.
–Press the FUNC key and keep it de-
pressed for 2 seconds.
FIL and the current setting appear in
the display:
0 = slight damping
➞fast determination of weight
1 = average damping
➞normal determination of weight
2 = strong damping
➞slow determination of weight
–Press an arrow key if you want to
change the set value.
–Press the FUNC key again to store the
displayed value. The scale is then back
in normal weighing mode.
The settings are retained even once
the scale is switched off.

6. Cleaning
Clean the rubber surface 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.
7. What do I do if…
… no weight display comes on?
– Is the scale switched on?
– Check the batteries.
– Is the plug contact for connecting the display to the scale correctly connected?
… 0.000 does not appear before weighing?
–Press the Start key 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.
… 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 de-
tected 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 Eand 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.

11.Disposal
Batteries
Do not throw used batteries away in do-
mestic waste. Dispose of batteries at col-
lection points in the vicinity. When buying
new batteries, select those low in harmful
substances and containing no mercury
(Hg), cadmium (Cd) or lead (Pb).

12.Warranty
A two-year warranty from date of delivery
applies to defects attributable to poor ma-
terials or workmanship. All moveable parts
- batteries, cables, mains units, recharge-
able 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 custom-
er’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 there-
fore be retained.
A claim under warranty will not be hon-
oured if the equipment is opened by per-
sons 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.
