Thank you for your decision to purchase Rossmax Bluetooth body fat scale. Please peruse this instruction manual prior to first start up and keep this user instruction careful so as to have this information on hand whenever it is needed.

Children should be supervised to ensure that they do not play with the scale.
Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults. BMI uses the following simple formula to indicate the ratio between weight and height of a person.
If the fat level revealed by BMI is higher than the international standard, there is an increased likelihood of common diseases. However, not all types of fat can be revealed by BMI.
BMI | Designation by the WHO |
Below 18.5 | Underweight |
18.5 – 24.9 | Normal weight |
25.0 – 29.9 | Pre-obesity |
30.0 – 34.9 | Obesity class I |
35.0 – 39.9 | Obesity class II |
Above 40 | Obesity class III |
The above index refers to the values for obesity judgment proposed by WHO(World Health Organization).
The body fat content is shown as the amount of stored fat as a percentage of total body weight. There is no generally accepted set value as this varies significantly according to gender (due to the different build) and age.
Body fat is vital for basic body functions. It's protecting organs, cushioning joints, regulating body temperature, storing vitamins and serves the body as energy storage.
As essential for women a minimum body fat proportion between 10% and 13% and for men between 10% and 13% is requested with the exception of competitive athletes.
Body fat is not a clear indicator for health. Too high body weight and a too high body fat proportion are linked to the incidence of many civilization diseases such as diabetes, cardiovascular diseases, etc.
Lack of movement and improper nutrition are often the prime course for these diseases. There is an obvious direct relationship between overweight and lack of movement.
Gender | Age | Under fat | Normal | Over fat | Obese |
Female | 20-39 | < 21.0 | 21.0 - 32.9 | 33.0 - 38.9 | ≥39.0 |
40-59 | < 23.0 | 23.0 - 33.9 | 34.0 - 39.9 | ≥40.0 | |
60-79 | < 24.0 | 24.0 - 35.9 | 36.0 - 41.9 | ≥42.0 | |
Male | 20-39 | < 8.0 | 8.0 - 19.9 | 20.0 - 24.9 | ≥25.0 |
40-59 | < 11.0 | 11.0 - 21.9 | 22.0 - 27.9 | ≥28.0 | |
60-79 | < 13.0 | 13.0 - 24.9 | 25.0 - 29.9 | ≥30.0 |

Hydration levels in the body may affect body fat readings. Readings are usually highest in the early waking hours, since the body tends to be dehydrated after a long night's sleep. For the most accurate reading, a person should take a body fat percentage readings at a consistent time of day under consistent conditions.
Besides this basic cycle of fluctuations in the daily body fat readings, variations may be caused by hydration changes in the body due to eating, drinking, menstruation, illness, exercising, and bathing. Daily body fat readings are unique to each person, and depend upon one's lifestyle, job and activities.
Regardless of your activity level, a minimum level of caloric intake is required to sustain the body's everyday functions.
Known as the resting metabolism, this indicates how many calories you need to ingest in order to provide enough energy for your body to function.
Visceral fat is a type of body fat that's stored within the abdominal cavity. It's located near several vital organs, including the liver, stomach, and intestines. It can also build up in the arteries. It is different from fat found directly underneath the skin, which is referred to as subcutaneous fat. Visceral fat is sometimes referred to as "active fat" because it can actively increase the risk of serious health problems such as high cholesterol, heart disease and type 2 diabetes. In order to prevent or improve these conditions, it is important to try to reduce the amount of visceral fat levels to an acceptable level.
