Body Fat
Measurement Range: 5~75% , Accuracy:
0.1%
Determines the portion of fat to the total body
weight.
Protein
Accuracy: 0.1%
Proteins are the main building block of the
body. They are used to make muscles, tendons,
organs, and skin. The percentage of protein in
total body weight is around 18%.
Body Mass Index
Accuracy: 0.1
Body Mass Index (BMI) is a calculation of a
person’s weight-to-height ratio. BMI can be
used to determine weight-related health risk.
Body Age
Accuracy: 1~3 years old
Your fitness age is estimated by all your body
measurement statistics.
Basal Metabolic Rate
Basal Metabolic Rate (BMR) is the
minimum calorie expenditure rate. This is
the rate at which you must expend calories in
order to keep alive. This measurement can be
helpful to weight-loss programs in predicting
weight-loss rates.
Measurement Range
Weight
Weight Range: 3kg~180kg /
6.6 ~ 396.8 Lbs
Unit: Kg/Lb, Accuracy 0.1kg
Water
Measurement Range: 15~70% ,
Accuracy: 0.1%
The percentage of body water in total body
weight is usually around
60%~70%.YUNMAI Smart Scale can
measure changes in your body water every
day..
Bone Mass
Accuracy: 0.1kg
The weight of bone tissue of the
body composition.
Skeletal Muscle
Measurement Range: 15~70% ,
Accuracy: 0.1%
Lean body mass consists of your bones,
ligaments, tendons, internal organs and muscles
– the body weight minus the fat weight.
Visceral Fat
Measurement Range: 1~30
Unlike subcutaneous fat, visceral fat is stored in
the abdominal cavity around several important
internal organs including the liver and pancreas.
A certain amount of visceral fat is essential as it
plays a role in the support, stability and
protection of internal organs.

As a precaution, persons with cardiac pacemakers, electrocardiographs and/or other
medical devices implanted in the body or used for life support, should not use
Bioelectric Impedance Devices directly. Please wear slippers to weigh yourself, the
scale will transmit an extremely weak electrical current when measuring body statistics,
and it could affect the other device.
Pregnant women: Please wear slippers to weigh yourself if you are pregnant. Due to
your special physical status, the scale will only show the weight.
Athletes and fitness coaches: Athletes have different body types. Scales with only foot
electrodes underestimate body fat in people with lots of body fat and overestimate it in
leaner people.
Under 18 years old: Only weight is available for young people under 18, because they
are growing too fast and their body data is changing too frequently.
Safety Precaution
Bioelectric Impedance Analysis devices pass an extremely weak electrical signal through the
body when taking a measurement. This weak electrical signal is not felt and is safe for
individuals.
