4. Incorrect measurement

If the scale detects an error during weighing, "FFFF" or "Err" 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 errors:
FFFF The maximum load-bearing capacity of
150 kg (330 lbs) was exceeded.
Err The electrical resistance between the elec-
trodes and the soles of your feed is too
high (e.g. with heavily callused skin).
Err Your body fat lies outside the measurable
range (less than 5% or greater than 60%).
Err Your percentage of water lies outside the
measurable range (less than 30% or greater
than 90%).
