Active Metabolic Rate; Results In Relation To Time; Troubleshooting - Beurer BF 520 Instruction Manual

reduces slightly with increasing age. You can reduce this degeneration somewhat with healthy nutrition (par-
ticularly calcium and vitamin D) and regular exercise. With appropriate muscle building, you can also strengthen
your bone structure.
Attention: Please do not confuse bone mass with bone density. Bone density can be determined only by means
of a medical examination (e.g. computer tomography, ultrasound). It is therefore not possible to draw conclu-
sions concerning changes to the bones and bone hardness (e.g. osteoporosis) using this scale. Little influence
can be exerted on bone mass, but it will vary slightly within the influencing factors (weight, height, age, gender).

Active metabolic rate

The active metabolic rate (AMR) is the amount of energy required daily by the body in its active state.
This AMR value is displayed automatically as soon as you select your user data symbol or
mode under settings.
To maintain your existing weight, the amount of energy used must be reintroduced into the body in the form of
food and drink. If less energy is introduced than is used over a longer period of time, your body will obtain the
difference largely from the amount of fat stored and your weight will reduce. If, on the other hand, over a long-
er period of time more energy is introduced than the total active metabolic rate (AMR) calculated, your body
will be unable to burn off the excess energy, and the excess will be stored in the body as fat and your weight
will increase.

9. Results in relation to time

Note:
Remember that only long-term trends are important. Short-term fluctuations in weight over a few days are usu-
ally the result of fluid change, due to fluid intake or loss.
The interpretation of the results will depend on changes in your overall weight and body fat, body water and
muscle percentages, as well as the period during which these changes take place. Sudden changes within days
must be distinguished from medium term changes (over weeks) and long term changes (months).
A basic rule is that short term changes in weight almost exclusively represent changes in water content, whereas
medium and long term changes may also involve the fat and muscle percentages.
• If your weight reduces over the short term, but your body fat percentage increases or remains the same, you
have merely lost water – e.g. after a training session, sauna session or a diet restricted only to rapid weight loss.
• If your weight increases over the medium term and the body fat percentage falls or stays the same, then you
could have built up valuable muscle mass.
• If your weight and body fat percentage fall simultaneously, then your diet is working – you are losing fat mass.
• Ideally you should support your diet with physical activity, fitness or power training. This way you can increase
your muscle percentage over the medium term.
• Body fat, body water or muscle percentages should not be added (certain elements of muscle tissue also
contain body water).

10. Troubleshooting

Following error messages can appear.
Error display Possible causes of errors
"0-Ld" The maximum capacity of 441 lb (200 kg,
31 st : 7 lb) has been exceeded.
"Err" The electrical resistance between the conduc-
tors and the soles of the feet is too high (e.g.
in the case of thick calluses or too dry soles).
"Err" The fat percentage is outside the measurable
range (less than 5 % or greater than 65 %).
"Err" The water percentage is outside the
measurable range (less than 25 % or greater
than 75 %).
Correction of errors
Weigh only the maximum permissible
weight.
Repeat the measurement barefoot.
If necessary, remove the calluses from the
soles of your feet.
