MEASUREMENT AND ANALYSIS
Precautions for Measurement
The reliability of the results can be assessed by its accuracy. The "Accuracy" of the device is determined
by comparing the actual body composition and the results from Body Composition Analyzer. The
"Reproducibility" is determined when the device gives the identical results under the same condition. In
order to maintain the accuracy of the results, the following guidelines should be kept.
1)
Water volume increases after a meal. Therefore, measure on an empty stomach.
Measure 3 ~ 4 hours after a meal.
Avoid beverages containing caffeine or beverages functioning as diuretics 4 hours before
measurement.
Drink 2 cups of water 2 hours before the measurement.
2)
Before measurement, the subject should be in a stable condition.
Measure 3 ~ 4 hours after a bath, a sauna, exercise or activity that causes a lot of sweating.
Or measure before these activities.
3)
Avoid drinking alcohol 24 hours before the measurement
4)
Wear clothes as light as possible.
5)
Once the subject is on the scale, avoid sudden movements from sitting to standing position etc.
Body fluid moves to the lower extremities and affects the results. Thus subjects should be measured
after maintaining a standing position for 5 minutes.
6)
Clean both the electrodes and the skin contact points.
7)
Changes in room temperature may affect the results. Measurement should be done in a
temperature around 20
°
C.
8)
Body composition and weight varies even throughout a day. Therefore, the measurement should
be performed at the same time every day. For a person who stands for a long period of time
during the day, it is advised to measure in the morning.
9)
Go to the bathroom before measurement.
10)
Maintain correct position and posture during the measurement.
