Determining and rating
body mass index (BMI)
Body mass index relates height and weight to one
another and consequently allows more accurate infor-
mation than ideal Broca weight, for example. A toler-
ance range is quoted which is considered ideal for
health.
The device has three memories for height. You can
enter and save the height of specific patients. Alterna-
tively, you can save different start values and thus set a
patient's actual height more quickly.
1. Ensure that the scale has no load.
2. Switch on the scale.
3. Press the (bmi/menu) arrow key briefly.
The message "BMI" appears.
The last memory used is displayed (in this case,
memory 2).
4. You can adopt the memory displayed or select a
different memory using the arrow keys.
5. Confirm your setting with Enter (send/print).
Arrows flash in the display.
