AMR
The active metabolic rate (AMR) is the amount of energy that the active body consumes each day. An indi-
vidual's energy requirement increases when the level of physical activity increases; the diagnostic bath-
room scale calculates this by means of the activity level (1-5) that has been entered.
To maintain the current weight, the energy that the body uses must be replaced in the form of food and
drink.
If less energy is taken in than is used over a long period of time, the body primarily takes the difference
from the fat stores, with resulting weight loss. However, if the amount of energy taken in exceeds the cal-
culated active metabolic rate (AMR) for a longer period, the body cannot burn off the excess energy. The
excess is stored in the body as fat, leading to weight gain.
Temporal context of the results
Note: Please note that only the long-term trend is important. Brief deviations in weight within a few
days are normally caused by loss of fluids.
The interpretation of the results is based on changes in total body weight, percentage of body fat, body
water and muscle content, as well as on the length of time over which these changes occur.
Rapid changes within the scope of a few days are to be considered separately from medium-term
changes (in the scope of weeks) and long-term changes (months).
It can be said as a basic rule that short-term changes in weight are almost entirely changes in water con-
tent, whereas medium-term and long-term changes may also relate to the fat percentage and the muscle
percentage.
• If your weight drops in the short term but your body fat percentage increases or stays the same, you
have only lost water, for example following a training session, visit to the sauna or a diet aimed only at
fast weight loss.
• 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 should not be totalled (muscle tissue also contains com-
ponents made of body water).

User assignment
It is possible to assign up to 10 scale users for a diagnostic measurement (barefoot).
For a new measurement, the scale assigns the measurement to the user whose most recently saved mea-
surement falls within +/- 3kg. If two or more users have potentially been recognised, the display switches
between them. Select your user by pressing the
Deleting scale data
If you would like to completely delete all measurements and old user data on the scale, switch on the
scale and press the UNIT button on the rear of the scale for approx. 6 seconds.
"CLr" will appear on the display for several seconds.
This is necessary if you would like to delete scale users who have been set up incorrectly or are no longer
required, for example.
Replacing the batteries
Your scale is equipped with a low battery indicator. If you operate the scale with flat batteries, "Lo" will
appear on the display and the scale will automatically switch off. In this case, the batteries must be
replaced (3 x 1.5 V AAA).
NOTE:
• When replacing the batteries, use batteries of the same type, make and capacity.
• Do not use rechargeable batteries.
• Use batteries free from heavy metals.
