If you think you are getting a inaccurate weight measurement, please try below steps to fix the

problem inaccurate issues:

  1. Place the scale on a hard and flat surface. Softer floors such as carpet can cause inaccuracies.
  2. Step on the scale with one foot until the LED screen lights up. Then step off and wait for the

LED screen to display“CAL”

. When "0.00" is displayed, the scale is calibrated and you could step

on it for measurement.

  1. During the measurement, try to keep your weight centered directly above and over the scale

as much as possible.

  1. Try waiting for the scale to auto-shutoff (about 10 seconds) and you should be able to view

accurate results via app.If you think you're still getting inaccurate results, it may be caused by the following factors:

  1. A type of internal error.

Try resetting the scale by taking one battery out for 5 seconds and putting it back in.

The unbalanced surface could also cause inaccurate results. Always try using the scale on a flat

surface. Putting it on a softer surface such as carpet can also cause inaccuracies.

  1. Check the legs/pads of the scale for any obstruction that may cause an imbalance.

Additional tips:

  1. Avoid moving the scale. Moving the scale frequently increases the risk of inaccuracy.
  2. Everyone's weight fluctuates throughout a typical day. Muscle usage and basic consumption of

food and water will cause some weight fluctuation no matter what. Thus, if you weigh yourself

multiple times during the day, you will see some differences. To minimize the fluctuations, weigh

yourself the same time each day (such as the morning).

We hope these tips are helpful and they address your issues.

Q: I saw "Athlete Mode" option when I create my profile, what is it? Should I

turn it on?

- What is the definition of an Athlete?A: The general consensus among researchers is that a quantitative dimension could be used to

define an athlete. An athlete is defined for this scale as a person who consistently works out for

approximately 3 times per week at 2 hours for each occurrence. These individuals should select

Athlete Mode for the most accurate measurement results.

Please note that scale is not calibrated for professional athletes or body builders.

Why is the Athlete Mode necessary in a Body Fat Scale?

It has been found that body fat estimation using BIA could overestimate the percentage body fat

of adult elite athletes. The physiological variation of athletes in bone density and level of

hydration are two of the reasons said to account for the difference.

H O W T O R E S T A R T T H E S C A L E ?

First, take one of the batteries out of the scale.

Then, put back the batteries and wait for 5 seconds.

Now the scale has been automatic restart, you can step onto the scale.

B O D Y C O M P O S I T I O N I N A C C U R A T E ?

Q: Why are my body composition numbers different than the ones I see at my

gym, doctor, etc.?

Body composition analysis is an inexact science, regardless of the manufacturer or method of

measurement. Because your scale combines the measurements it takes with variables stored in

your user profile according to our algorithm, the numbers you see may vary from those you see

using other measurement methods—which is completely normal. When you’re measuring body

composition, it’s more important to pay attention to overall trends than day-to-day numbers.

(Tracking in the FITINDEX app helps with that.)
