Foreword
With the continuous development of clinical nutrition, how to accurately and comprehensively
evaluate the nutritional status of individuals, better implement clinical nutrition support treatment, and
promote early recovery, has been paid more and more attention by the general population. In recent
years, the rapid development of human composition determination methods can provide important
clinical nutritional information for assessing the nutritional status of the human body. On the one hand,
it can be used to prevent epidemic diseases such as obesity, and on the other hand, it can guide the
administration of reasonable diet and exercise. Bioelectrical impedance technology (BIA) is a
detection technology that extracts the electrical impedance information of the organism to reflect the
biomedical information related to the physiology and pathology of the organism. The human body
composition analysis is an important application branch of bioelectrical impedance technology, it is
through the detection of human body impedance information to get the parameters of each component
of the human body. Human body composition analyzer is simple, accurate, non-invasive, safe, low
cost and a wide range of people and other advantages, whether it is academic and commercial, have
been vigorously developed.
Thank you for purchasing the Intelligent Body Composition Analyzer.

一、Product Overview
The Body Composition Analyzer mainly through the measurement of body weight, bioimpedance and height,
age, gender set to calculate the body's BMI, body fat rate, body water and other indicators; In addition, the data can
be directly uploaded to APP via Bluetooth or to server via WiFi connection, and then the server will push the data to
APP to generate in-depth test report. The body composition analyzer is suitable for individuals, family users and
other long-term monitoring of body obesity, to provide data reference for weight loss and muscle gain.

4、Basic information
This product can measure body weight, fat percentage, BMI and other indexes. After the measurement is
completed, the data will be transmitted to the mobile terminal application software through Bluetooth 4.0 or WiFi.
1、Measurement method
7
Place in a hard and flat place for use, do not use on uneven soft materials (such as: soft floor, carpet or spring
pad, etc.), otherwise it can not be measured correctly.
• Do not place in direct sunlight, near heating equipment, air outlet of air conditioning
• Do not use in places with drastic temperature changes
• Do not place it in a humid or steamy place
Body fat percentage is obtained by the BIA bioreactance measurement, which is closely related to the following
parameters: body resistance coefficient/height/weight/age/sex. So change any one of these parameters and the fat
percentage changes.
Also please do not measure under the following conditions:
• After strenuous exercise
• After a bath or sauna
• After overeating
• After drinking a lot of water or alcohol
• Cold and fever
The body weight changes daily with the change of eating and drinking water, there are 0.5~2KG of the change
value. Since body fat percentage = fat weight/body weight, fat percentage also fluctuates, as shown in the figure
below. In the morning, before eating and drinking, body fat percentage peaks throughout the day, and in the afternoon
and evening, body fat percentage peaks throughout the day as weight gain and water content increase due to eating
and drinking.
