1. Congratulations!
By purchasing the seca 767 electronic
personal 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 767 electronic personal scale 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.
In addition to the conventional determination of weight, the seca 767 also has a
function for determining body mass index.
For this purpose, height is entered on the
keypad and the body mass index associated with the weight value is output.
Its low power consumption means that with
a set of batteries, the seca 767 can be
used on a mobile basis for long periods.

Taring weight display (TARE)
The tare function is very useful, for example for determining the weight of a child, animal
or other object placed on the scale in addition to yourself.
Proceed as follows:
– Press the green Start key.
– First stand on the scales yourself without the additional weight and activate
the Tare function by depressing 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 take the additional load onto the
scale. You can leave the scale to do so,
in which case ---- appears.
The scale determines the weight of the
additional load. You can now perform
as many weighing operations as you
– 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
– 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.
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, 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.
– Step on the scale and keep still.
– Read off the BMI on the digital display
and compare it with the categories on
page 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 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.
6. 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?
… 0.0 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 running low. Change the batteries in the next few days.
… batt appears in the display?
– Batteries are empty. Put in new batteries.
… 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
– 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.

damage to the scale.
10. Disposal
Disposing of the scale
Do not throw used batteries away in domestic waste. Dispose of batteries at collection points in the vicinity. When buying
new batteries, select those low in harmful
substances and containing no mercury
(Hg), cadmium (Cd) or lead (Pb).
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.
