Automatic switch-off/economy mode
The scale switches off automatically after 20 seconds.
Weighing with measurement of BMI, body fat and body water
The seca 720/818 can also calculate the following body data in addition to weight: Body
Mass Index, body fat and body water proportion. For this purpose, an imperceptible,
harmless AC electric current is passed through the body and the measured values clas-
sified by weight, gender, build and height. These data must previously have been entered
in the scale (see "Storing personal data" on page 16).
So that your values are determined correctly and are comparable with one another over
several days, please note the following instructions:
• You should perform the measurement
barefoot, otherwise there is insufficient
contact with the sensors (in this case
will appear in the display). If you

have very dry skin, moisten your feet
slightly to improve conductivity.
• Stand as still as possible during meas-
urement.
• Position both feet so that they are as
much in contact with the sensors as
possible (see Fig. 6).
• Enter your height as exactly as possi-
ble. An error of just 2.5 cm will lead to
a deviation of 1 litre body water in the
calculation!
• Wherever possible, perform the meas-
urements each day at the same time
and under the same conditions, e.g. 15
minutes after getting up. Measure-
ments taken directly after sleeping give
Storing personal data
The seca 720/818 can store personal data for up to four different people. In addition, it
is possible to perform a measurement in so-called Guest Mode (see "Measuring in Guest
Mode" on page 18). The four personal memories are each assigned to one of the four
keys 1 GUEST, 2 ▲, 3 ▼ or 4 SET, and can subsequently be selected using these keys
when the scale is switched on.
– Switch on the scale using the one of the
four keys (1 GUEST, 2 ▲, 3 ▼ or
4 SET) to the memory of which the per-
sonal data is to be assigned.

implausible results, because body wa-
ter is distributed differently throughout
the body during sleep.
• Measurements taken directly after
strenuous physical exercise also give
implausible results. Take a relatively
long break (approximately 2-3 hours)
before measuring.
• Heavy meals or drinking of alcohol also
give implausible results.
• In the following cases, exact measure-
ments cannot be performed using the
seca 720/818: during pregnancy or if
your body contains medical implants
such as artificial joints, metal plates or
screws. In such cases, you should
have your doctor carry out a differential
diagnostic examination to obtain cor-
rect results.

The display will show the most recently-

– You can change the value in the incre-

display using arrow keys 2 ▲ and 3 ▼.
– Once the correct value has been set,
briefly press the 4 SET key.
