Why is my body weight not accurate?

Q: Why is my body weight not accurate?

A: 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.
3. During the measurement, try to keep your weight centered directly above and over the scale as much as possible.
4. 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:
A.  A type of internal error.

[For Batteries Models]:

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

[For rechargeable Models]:

There is a [RESET] button on the back of the scale, please press it for 5 seconds to restart the scale.
B. 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.
C. 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)
3. Accuracy Range:
50kgs: ± 0.3kg
100kgs ± 0.4kg
150kgs ± 0.5kg
110lbs: ± 0.66lb
220lbs ± 0.88lb
330lbs ± 1.1lbs
We hope these tips are helpful and they address your issues.

What is "Athlete Mode"?

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.

[For Batteries Models]:

Body Composition Inaccurate?

Q: Why are my body composition numbers different than the ones I see at my gym, doctor, etc.?

A: 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 Renpho app helps with that.)


How to change the unit?

Q: How to change the unit?
