NOTE:
• O
nly long-term trends are important. Brief deviations in weight within a few days are normally caused by
loss of fluids.
Interpretation of these results is based on changes in total body weight, percentage of body fat, body water
and muscle content, as well as the length of time over which these changes occur. Rapid changes within the
scope of a few days are considered separately from medium-term changes (in the scope of weeks) and long-
term changes (months). As a basic rule, short-term changes in weight are almost entirely changes in water
con tent, whereas medium-term and long-term changes may relate to fat percentage and muscle percentage.
If you experience short-term weight loss but your body fat percentage increases or stays the same, you have
only lost water, such as after a training session, visit to the sauna, or a diet aimed only at fast weight loss.
On the other hand, if your weight increases in the medium term and your body fat percentage drops or stays
the same, you may have built up valuable muscle mass.
If your weight and body fat percentage both fall at the same time, then your diet is working – you are losing
fat mass.
Ideally, you should support your diet with physical activity, fitness or strength training. This enables you to
increase your muscle percentage in the medium term.
Body fat, body water and muscle percentages must not be added (muscle tissue also contains compo nents
made of body water).
8. Care and Maintenance
Clean the scale periodically using a damp cloth and, if necessary, a small amount of mild detergent.
9. Troubleshooting
If the scale encounters an error during measurement, “FFFF” or “Err” is displayed. If you step onto the scale
before it displays “0.0”, incorrect values may display.
Error display Possible causes of errors Correction of errors
„FFFF“ The maximum capacity of 400 lb (180 kg,
28 st) has been exceeded.
Weigh only the maximum permissible weight.
„Err“
The electrical resistance between the con-
ductors and the soles of the feet is too high
(e.g. in the case of thick calluses or too
dry soles).
Repeat the measurement barefoot.
If necessary, remove the calluses from the
soles of your feet.
„Err“ The fat percentage is outside the measur-
able range (less than 5 % or greater than
50 %).
Repeat the measurement barefoot.
If necessary, remove the calluses from the
soles of your feet.
„Err“ The water percentage is outside the mea-
surable range (less than 25 % or greater
than 75 %).
Repeat the measurement barefoot.
If necessary, remove the calluses from the
soles of your feet.
„Err“
The muscle percentage is outside the mea-
surable range (age and gender related).
Repeat the measurement barefoot.
If necessary, remove the calluses from the
soles of your feet.
