Zero related issues
Q1: What does it mean that the scale surface keeps rotating after the power is on?
A: To ensure weight accuracy, the scale will enter the zero chasing mode after each power-on. The equipment needs to be placed on hard and flat ground and can be used when the zero chasing display is 0.0kg.
Q2: Is there a small weight on the scale that does not return to zero?
A:
1. Please check if the ground is hard and flat, as uneven ground can have residual effects;
2. To ensure the accuracy of weighing, the scale has a dynamic zero-chasing mechanism;
3. The scale will track zero when the balance screen stops, clear the weight on the scale surface, and return to the zero state;
4. During the use of the scale, if the scale body is moved, the zero point will change. After the scale is placed on the ground, a small weight value will be primary on the display screen. At this time, you need to wait 5 seconds to clear the screen, then wake up the scale surface to display 0.0kg before using it.
Weighing related issues
Q1: What are the precautions for the Xiaomi Body Composition Scale S400 when weighing?
A:
1. Please ignore the results of the first weighing or the first weighing after moving the scale;
2. Avoid stepping on the edge of the scale to prevent tipping and falling;
3. Place the scale on a hard and flat floor for weighing;
4. For weighing small objects weighing less than 5kg, it is necessary to lightly step on or press the scale surface, wake up the scale body, and wait for the scale surface to display 0.0kg before measuring.
When there is a weight residual value on the empty scale. Please wait 5 seconds for the scale surface to rest, lightly step on it to wake up the display of 0.0kg, and then load the scale for measurement.
Q2: What is the weighing range for small objects for the Xiaomi Body Composition Scale S400?
A:
1. The function of weighing small objects is enabled by default, and the device can recognize small objects weighing between 0.1kg and 10kg. It only measures the weight and does not save it;
2. For weighing small objects weighing less than 5kg, it is necessary to lightly step on or press the scale surface, wake up the scale body, and wait for the scale surface to display 0.0kg before measuring.
Q3: What is the accuracy and division of weighing?
A: The Xiaomi Body Composition Scale S400 has a measurement accuracy error. Generally speaking, the higher the weight, the greater the error, and the accuracy deviation it has is as follows:
100g ≤ m＜10kg, maximum error ± 0.1kg;
10kg ≤ m＜50kg, maximum error ± 0.1kg;
50kg ≤ m＜100kg, maximum error ± 0.2kg;
100kg ≤ m ≤ 150kg, maximum error ± 0.3kg;
Deviation within the range is considered normal measurement, please feel free to use it. Due to biased loading, there may be significant deviations in real-person measurement. Users need to smoothly load the scale and maintain the center of gravity in the middle of the scale body to ensure that the correct value is obtained.
Q4: Is the data for continuous weighing different?
A: You can troubleshoot by following these steps:
1. Please place the equipment on a hard and flat surface before re-weighing and measuring. Do not place on soft or uneven surfaces;
2. Check if the equipment casing is in contact with walls or other objects. If available, please keep the scale away from walls or objects;
3. Did you move the body of the scale during use? After moving the scale, the zero point will change. After the scale is placed on the ground, a small weight value will be primary on the display screen. At this time, you need to wait for 5 seconds to clear the screen, then wake up the scale to display 0.0kg before using it;
4. Use the correct weighing and standing posture, keep the center at the center of the scale, and do not shake your body during the measurement process.
Q5: How much weight fluctuation is normal for the human body in one day?
A:
1. The normal daily weight fluctuation of a person is about 1-3kg, which is within the normal range;
2. Because everyone's daily dietary composition is different, the amount of food they eat is not very constant, and the amount of water they drink and the amount of exercise they exercise have a certain impact on their weight. It is best to set a fixed time every day when weighing, which can be after using the toilet in the morning, before meals, or at night. In short, it is necessary to set a fixed time for comparability;
3. We should fully understand the daily weight fluctuations. If the weight continues to decline, for example, if the weight drops more than 10% of the original weight every month, we should pay attention to whether there are pathological factors. In addition to deliberate weight loss, we should pay attention to whether there are diabetes, hyperthyroidism, tuberculosis, tumors, and gastrointestinal diseases that may lead to weight loss.

3. Please ensure the scale surface is clean and free from metal foreign or water stains;
4. When measuring, please go barefoot on the scale and stand on the scale surface correctly, with your feet fully in contact with the electrode sheet, your hands naturally droop, and maintain the correct measuring posture;
5. Stand upright and steady without shaking your body or feet when taking measurements. Bending over, kneeling or leaving your feet may result in inaccurate measurements;
6. If the weight measurement is not accurate after moving the scale body, please put the scale in place and step on the bright scale. When the scale shows "0.0kg", the scale can be used to measure the weight normally;
7. It is suggested to measure at the same time and under the same conditions every day, to observe the change trend of these data more accurately.
Q15: Is there any error in the heart rate measurement data?
A: When the scale is inaccurate in measuring heart rate, please conduct the following investigation:
1. The heart rate measured by the scale in a calm state is a single heart rate. There will be differences between the "heart rate" measured in a calm state and that measured in different scenes just after exercise. The normally measured "heart rate" value in a calm state is 60~ 100 (times/minute). When you do not measure the "heart rate" in a calm state, the "heart rate" data measurement will be affected if there is body shaking, large-scale movements or loud talking. It is recommended to keep calm during the "heart rate" measurement and avoid body shaking, large-scale movements or loud talking;
Note: The heart rate measurement on the scale needs to be detected at rest, which is not suitable for measurement during or immediately after exercise.
2. Use the correct measurement method As the heart rate changes dynamically and different devices measure the heart rate on different principles, there will be certain differences in measurement, and the heart rate measured by the scale is compared and calibrated with the industry gold standard heart rate band, and the heart rate measurement accuracy is high. Attention should be paid when using the scale to measure the heart rate:
(1). Open your feet, keep from sole to thigh and do not contact each other;
(2). To maintain foot muscle relaxation;
(3). Keep a steady state of rest, don't shake;
(4). Don't talk while measuring;
(5). Maintain normal breathing, do not breathe sharply or deeply;
(6). Maintain full contact between the sole and the electrode sheet.

11. Bone salt content: Bone salt amount refers to the total amount of minerals in the bone;
12. Bone salt rate: Bone salt rate refers to the proportion of bone salt in total body weight;
13. Protein quality: Protein refers to the total amount of protein in the human body;
14. Protein rate: Protein rate refers to the proportion of protein mass in total body weight;
15. Body score: The primary parameters of the body score are BMI, body fat rate, muscle mass and (specific parameters). Assume that each parameter is 100 points under the most standard range, and the scores beyond and below the standard range decrease accordingly (set the decreasing layer), and then set the weight according to the influence of each parameter on the physical condition. The final score is based on the combination of each parameter;
16. Visceral fat grade: Visceral fat is a kind of human body fat essential for stabilizing and protecting human organs. However, too much visceral fat will increase the risk of cardiovascular diseases and metabolic diseases;
17. Basal metabolic rate: Basic metabolism refers to the energy metabolism per unit time in the basic state(the human body is quiet, awake, fasting, and the room temperature is 20~25 degrees Celsius). This energy metabolism is the minimum energy needed to maintain life activities;
18. Weight control: Weight control = standard weight reference value-current weight, for reference only;
19. Muscle control: Muscle control = standard muscle mass reference value-current muscle mass, for reference only;
20. Fat control: Fat control amount = standard fat amount reference value-current fat amount, for reference only;
21. Body type(Body shape judgment): According to the user's body fat rate and BMl, the body shape is comprehensively determined;
22. Presumed waist-to-hip ratio: The estimated waist-to-hip ratio mainly reflects the state of fat distribution in the human body. It can be obtained by calculating the ratio of waist circumference(cm) and hip circumference(cm). The estimated waist-to-hip ratio is for reference only;
23. Physical age: Physical age refers to a combination of weight, height, fat, muscle and other indicators based on basal metabolic rate, which mainly depends on lifestyle and health status;

Q3: What is the accuracy and division of weighing?
A: The Xiaomi Body Composition Scale S400 has a measurement accuracy error. Generally speaking, the higher the weight, the greater the error, and the accuracy deviation it has is as follows:
100g ≤ m＜10kg, maximum error ± 0.1kg;
10kg ≤ m＜50kg, maximum error ± 0.1kg;
50kg ≤ m＜100kg, maximum error ± 0.2kg;
100kg ≤ m ≤ 150kg, maximum error ± 0.3kg;
Deviation within the range is considered normal measurement, please feel free to use it. Due to biased loading, there may be significant deviations in real-person measurement. Users need to smoothly load the scale and maintain the center of gravity in the middle of the scale body to ensure that the correct value is obtained.
Q4: Is the data for continuous weighing different?
A: You can troubleshoot by following these steps:
1. Please place the equipment on a hard and flat surface before re-weighing and measuring. Do not place on soft or uneven surfaces;
2. Check if the equipment casing is in contact with walls or other objects. If available, please keep the scale away from walls or objects;
3. Did you move the body of the scale during use? After moving the scale, the zero point will change. After the scale is placed on the ground, a small weight value will be primary on the display screen. At this time, you need to wait for 5 seconds to clear the screen, then wake up the scale to display 0.0kg before using it;
4. Use the correct weighing and standing posture, keep the center at the center of the scale, and do not shake your body during the measurement process.
Q5: How much weight fluctuation is normal for the human body in one day?
A:
1. The normal daily weight fluctuation of a person is about 1-3kg, which is within the normal range;
2. Because everyone's daily dietary composition is different, the amount of food they eat is not very constant, and the amount of water they drink and the amount of exercise they exercise have a certain impact on their weight. It is best to set a fixed time every day when weighing, which can be after using the toilet in the morning, before meals, or at night. In short, it is necessary to set a fixed time for comparability;
3. We should fully understand the daily weight fluctuations. If the weight continues to decline, for example, if the weight drops more than 10% of the original weight every month, we should pay attention to whether there are pathological factors. In addition to deliberate weight loss, we should pay attention to whether there are diabetes, hyperthyroidism, tuberculosis, tumors, and gastrointestinal diseases that may lead to weight loss.

1. If the account of the family member is not bound to this device, they can use "device sharing" to bind the device for measurement;
2. If already bound, please follow the operating instructions to correctly operate the measurement;
3. There is a situation where the weight of family members and oneself is close, with a deviation of within ± 2kg. The scale body cannot recognize which user's data it is. Please claim it in the pending data section of the app.
Note: If two members in a family with similar weight need to be measured for long-term use. It is recommended to purchase a new one and use it separately.
Q9: What age and height are suitable measurements for the Xiaomi Body Composition Scale S400?
A:
1. The Xiaomi Body Composition Scale S400 is suitable for people aged 6-80 for full data measurement;
2. For Under 6 years old and above 80 years old. Fat measurement is not supported currently. Only weight measurement is allowed;
3. The supported height range is 90-200cm;
4. The weight range supported by the algorithm is 20~150kg.
Q10: What if body composition analysis fails?
A: The following steps can be followed for troubleshooting:
1. Please confirm if the scale has been bound and connected;
2. Please check if the user information on the Profile page of the app, such as gender, birthday, and height, is correct. At present, the supported range of fat measurement algorithms is age: 6-80 years old; Height: 90-220cm; Weight: 20-150kg;
3. Please confirm if you are weighing barefoot, with your feet separated and your feet in full contact with the electrode;
4. Please ensure that the measurement process does not involve pre-weighing;
5. During the measurement process, there is no movement of the feet.
Reminder: The weather in the autumn and winter is cold and dry, which may lead to poor electrode contact and measurement failure. I suggest you use a damp towel to lightly wipe and wet the soles of your feet before trying again.
Q11: How do the Xiaomi Body Composition Scale S400 identify users?
A: After device binding, the scale end will save user information. Later measurements will match users based on weight differences (the system will identify users with weight differences within 2kg as the same user). And synchronize measurement data.
Q12: Can two people with similar weights be recognized?
A:
1. Users with a weight difference in the range of ± 2kg cannot recognize it;
2. It is recommended to use the Share device function of the account and share it with another person. When using it, keep the Bluetooth connection to measure. When offline, the scale side cannot recognize the only user.
Q13: How is pending data generated?
A:
1. When the scale measures the weight, it is identified with the last weight record of the existing user in the scale end or APP to determine whether it is within the range of ± 2kg;
2. If a unique user is identified, this data will be attributed to this account;
3. If the user is not recognized (scale display ----) or to identify multiple users (scale display ----), will this data be determined to be claimed data, stored in the scale or APP, APP to be connected next to be claimed in the library by the user to select the home;
4. After claiming the data, the APP will assign the data to the corresponding date according to the time. To query, you need to check the claimed data in all the data.
Q14: Is there any error in weight and body fat measurement data?
A: Please check and confirm the following:
1. Open the Mi Home/Xiaomi Home app, select "Settings" >> "User Management" >> Select Account, and check whether the gender, birthday, and height information is filled in correctly;
2. Please ensure the scale is on a hard, flat floor. Do not place it against the wall to ensure the foot of the scale is free of foreign matter and is not in the brick seam;
3. Please ensure the scale surface is clean and free from metal foreign or water stains;
4. When measuring, please go barefoot on the scale and stand on the scale surface correctly, with your feet fully in contact with the electrode sheet, your hands naturally droop, and maintain the correct measuring posture;
5. Stand upright and steady without shaking your body or feet when taking measurements. Bending over, kneeling or leaving your feet may result in inaccurate measurements;
6. If the weight measurement is not accurate after moving the scale body, please put the scale in place and step on the bright scale. When the scale shows "0.0kg", the scale can be used to measure the weight normally;
7. It is suggested to measure at the same time and under the same conditions every day, to observe the change trend of these data more accurately.
Q15: Is there any error in the heart rate measurement data?
A: When the scale is inaccurate in measuring heart rate, please conduct the following investigation:
1. The heart rate measured by the scale in a calm state is a single heart rate. There will be differences between the "heart rate" measured in a calm state and that measured in different scenes just after exercise. The normally measured "heart rate" value in a calm state is 60~ 100 (times/minute). When you do not measure the "heart rate" in a calm state, the "heart rate" data measurement will be affected if there is body shaking, large-scale movements or loud talking. It is recommended to keep calm during the "heart rate" measurement and avoid body shaking, large-scale movements or loud talking;
Note: The heart rate measurement on the scale needs to be detected at rest, which is not suitable for measurement during or immediately after exercise.
2. Use the correct measurement method As the heart rate changes dynamically and different devices measure the heart rate on different principles, there will be certain differences in measurement, and the heart rate measured by the scale is compared and calibrated with the industry gold standard heart rate band, and the heart rate measurement accuracy is high. Attention should be paid when using the scale to measure the heart rate:
(1). Open your feet, keep from sole to thigh and do not contact each other;
(2). To maintain foot muscle relaxation;
(3). Keep a steady state of rest, don't shake;
(4). Don't talk while measuring;
(5). Maintain normal breathing, do not breathe sharply or deeply;
(6). Maintain full contact between the sole and the electrode sheet.

11. Bone salt content: Bone salt amount refers to the total amount of minerals in the bone;
12. Bone salt rate: Bone salt rate refers to the proportion of bone salt in total body weight;
13. Protein quality: Protein refers to the total amount of protein in the human body;
14. Protein rate: Protein rate refers to the proportion of protein mass in total body weight;
15. Body score: The primary parameters of the body score are BMI, body fat rate, muscle mass and (specific parameters). Assume that each parameter is 100 points under the most standard range, and the scores beyond and below the standard range decrease accordingly (set the decreasing layer), and then set the weight according to the influence of each parameter on the physical condition. The final score is based on the combination of each parameter;
16. Visceral fat grade: Visceral fat is a kind of human body fat essential for stabilizing and protecting human organs. However, too much visceral fat will increase the risk of cardiovascular diseases and metabolic diseases;
17. Basal metabolic rate: Basic metabolism refers to the energy metabolism per unit time in the basic state(the human body is quiet, awake, fasting, and the room temperature is 20~25 degrees Celsius). This energy metabolism is the minimum energy needed to maintain life activities;
18. Weight control: Weight control = standard weight reference value-current weight, for reference only;
19. Muscle control: Muscle control = standard muscle mass reference value-current muscle mass, for reference only;
20. Fat control: Fat control amount = standard fat amount reference value-current fat amount, for reference only;
21. Body type(Body shape judgment): According to the user's body fat rate and BMl, the body shape is comprehensively determined;
22. Presumed waist-to-hip ratio: The estimated waist-to-hip ratio mainly reflects the state of fat distribution in the human body. It can be obtained by calculating the ratio of waist circumference(cm) and hip circumference(cm). The estimated waist-to-hip ratio is for reference only;
23. Physical age: Physical age refers to a combination of weight, height, fat, muscle and other indicators based on basal metabolic rate, which mainly depends on lifestyle and health status;
