The next time the scale will recognize the user according to the weight value.

For APP CONNECTION function：

Your scale supports unlimited number of users.

Three types of users are supported:

(1) Individual scale users. Each person downloads Fit Profile app to one’s own smartphone, creates a separate individual account. The user’s measurement data syncs with the user’s own app. Each person is independent and keeps measurement data private. This is the most common practice for multiple people to use one scale. Share the scale but not the data. To make sure to keep your measurement private, you need to open your app each time when you use the scale, so your measurements will be synced to your app immediately.

(2) A scale user is under an account owner. The user does not have an independent account. This user’s measurements sync to the account owner’s app. The account owner has measurement data of all users. Some examples of this type of users are children under their parents, or a group of people under their coach. It is ideal for parents to track their children’s weights or fitness coaches to track their clients’ progresses.

To add such a user, please do following.

Tap on “Account” icon on the top, then tap on “Add user”

You need to fill in this new user’s name and personal info. Tap on “Confirm” when complete.

(3) The 3rd type is called “Friends”. Each friend has an individual account, syncs data to one’s own account. One user can “Add Friends”, then a friend request will be sent out. After the friend request is accepted, the two users become “Friends”. Between the two friends, they can view each other’s measurement history but not other’s personal information in the profile. It is great for weight loss buddies to hold each other accountable and encourage each other.

To add such a Friend, go to “Me” > “Friend” > “Add Friend”.

Input your friend’s Email then we will send an invitation to him/her. After adding a friend, you can view the measurement data of your friend.

Like most household body fat scales, the Fit Plus KN Smart Body Composition Scales use the Bio-electrical Impedance Analysis or Bioimpedance Analysis (BIA) Method to assess body compositions. Measuring body fat in relation to lean body mass, it is an integral part of a health and nutrition evaluations.

This non-invasive test simply involves your feet touching four electrodes on the scale. A low level, imperceptible electrical current is sent through the body. The flow of the current is affected by the amount of water in the body. The device measures how this signal is impeded through different types of tissue. Tissues that contain large amounts of fluid and electrolytes, such as blood, have high conductivity, but fat and bone slow the signal down. As BIA determines the resistance to flow of the current as it passes through the body, it provides estimates of body water from which body fat is calculated using selected algorithms.

It is why the measurements need to be done barefoot, with user’s both feet on the scale touching the metal pads.

In general, to properly use the Fit Plus KN Body Composition Smart Scale is easy and straightforward. You just do it naturally, like using a traditional digital bathroom scale. The following provides some general guidelines. To those who need to read warnings or special attentions about the scale, please check below:

WARNING

Professional Bodybuilders: This product is for typical consumers, thus may not suit for you. Bodybuilders incur special body muscle and fat percentages, results from this scale may not match measurements from specialized instruments or medical equipment. We recommend you pay attention to long-term changes in the data, rather than measurement values themselves.

Pregnant Women: Your body compositions differ during your pregnancy. Other than the body weight, this scale is not designed to make accurate measurements for pregnant women.

Children: This scale is not designed for babies or toddlers under 4 years old. For children under the age of 18, not all the measurements are suitable. Children are growing faster than adults, and currently there is no widely adopted standard for categorizing measurements for children.

(1) Place the scale on a flat hard surface, such as tile or hardwood floors. Don’t place the scale on soft carpet.

(2) Make sure your gender, age and height info in the profile are correct.

(3) Choose right mode: Athlete or regular. People who are athletes or muscular, should choose Athlete mode.

(4) Calibrate the scale before measurements. Apply pressure to turn on the scale and wait “CAL” back to “0.0”. At this point, calibration is complete.

(5) Now you are ready to measure. Step on the scale barefoot, no socks or shoes. Make sure your both feet are on the electrode pads on either side. Stand still without movements during measurement. Your weight will flash twice, and “0” move back and forth. When your weight displays again, your measurement is done.

(6) In order for measurements comparable, take measurements at about same time and under similar conditions. Empty bladder before weighing. Do not measure when your body is wet.

The main components of the chemical structure of human body include fat tissues, water, protein, and inorganic tissues. A fat tissue is mainly comprised of fat and water, wherein water accounts for about 25% of total fat tissues. A muscle tissue is mainly comprised of protein and water, wherein water accounts for about 70% of total muscle tissues.

This body fat scale measures contents of fat tissues, muscle tissues, water, bone, and other major tissues in human body. Due to various tissues containing certain proportions of water, the sum exceeds 100% when all the measured components are added up.

Wake up the scale by pressing it until “0.00” display on the screen, and press the SET button for 3 seconds（Please make sure the scale is on a hard flat surface, not for carpet or any other soft surface ).

This means you have not completed the profile data first-time using.

Your body weight and your body compositions do change. It is normal to see your measurements fluctuate. Even within the same day, you may see different results when measuring at different times. We suggest you measure around same time and under similar conditions (e.g., before dinner) to maintain measurements consistent and comparable.

In terms of body fat and other body compositions, different equipment may give your different readings. Better to focus on relative changes of the values measured by a same device over long term.

Here are common causes and solutions:

(1) Your scale was not placed on a flat and hard surface. Please place your scale on a flat and hard floor. Avoid carpets and rugs.

(2) The scale did not properly reset. It has a residual number. You need to perform another power-on reset. Push the active button(next to the charging port), IMMEDIATELY place the scale on a flat hard surface. Make sure the scale displays “0.0”, and then close the battery cover.

(3) The scale was not calibrated when weighing. For each measurement, after turn the scale on, you need to wait “CAL” back to “0.0” before you step to take your measurement.

(4) Getting off your scale too soon may lead to inaccurate readings. Please stay on the scale until your weight number is stable.

There are several possibilities when a scale LED display doesn’t work properly.

(1) LED no display: Check the batteries. Check if the batteries are installed properly or replace new batteries if necessary.

(2) LED displays “Lo”: “Lo” refers to Low Battery. Check if the batteries are installed properly or replace new batteries if necessary.

(3) LED displays “EEr” ”Err1””Err2”: “EEr” refers to Error. The scale sensor may be overloaded or even damaged. Don’t use the scale if your weight is over the range. This scale only works for less than 396 lbs (180 kg).
