10.5 Calculation of the Body Mass Index
You need to know a person's body height before you can calculate the BMI for that
person. It should either be known or can be determined directly with the MPE-HM
and MPE-HEM model.
10.5.1 Measuring body height (MPE-HM and MPE-HEM only)

Push measuring stick upwards and set the stopper horizontally.

Push measuring rod carefully down until the headpiece touches the person's
head. (It is recommended to take measurements with shoes removed).
A fixed stopper pointing outwards poses a risk of injury.
