Note that with very muscular physiques (body builders), the BMI interpretation will show overweight.

The reason for this is that no account is taken of well above average muscle mass in the BMI formula.

Results in relation to time

Note that it is only the long-term trend which counts. Short period fluctuations in weight over a few days

are mostly the result of a loss of fluid.

The interpretation of the results will depend on changes in your: overall weight and body fat, body water

and muscle percentages, as well as on the period during which these changes take place. Rapid 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.

6. Incorrect measurement

If the scale detects an error during weighing, „FAT ” or “ ” appears in the display.

If you step onto the scale before “0.0” appears in the display, the scale will not operate properly.

Possible causes of error:

– The maximum load-bearing capacity of 150 kg

(330 lbs) was exceeded.

Remedy:

– Only weigh the maximum permissible weight.

– The electrical resistance between the electrodes

and the soles of your feed is too high (e.g. with

heavily callused skin).

– Repeat weighing barefoot. Slightly moisten the

soles of your feet if necessary. Remove the cal-

luses on the soles of your feet if necessary.

– Your body fat lies outside the measurable range

(less than 5 % or greater than 80 %).

– Repeat weighing barefoot.

– Slightly moisten the soles of your feet if neces-

sary.

– No response.

– Cover solar cells and apply pressure to the plat-

form for approx. 5 seconds. Repeat weighing with

sufficient light.
