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. Take off your shoes and socks and make sure both feet are on the electrode plates on either side.
3. During the measurement, try to keep your weight centered directly above and over the scale as much as possible.
4. Keep standing on the scale for about 10 seconds. Even if your weight is displayed, the scale may still be measuring your other body metrics; do NOT step off the scale while the scale is still measuring. After about 10 seconds, the display will go blank and a sound will indicate completion of the measuring process. You should then be able to view your body metrics in the app. (Sound settings can be changed in the Settings menu).
If you think you're getting inaccurate results, it may be caused by the following factors:
- A type of internal error. Try resetting the scale by taking one battery out for 5 seconds and putting it back in. If you are using a rechargeable scale, try pressing the reset button on the back of the scale for 5 seconds.
- An unbalanced floor could also cause inaccurate results. Always try using the scale on a flat surface. Putting it on a soft surface such as carpet can also cause inaccuracies.
- 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. 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:
110lbs: ± 0.66lb
220lbs: ± 0.88lb
330lbs: ± 1.1lbs
You can test the scale's accuracy by placing a 5 or 10 pound dumbbell on the scale and viewing the measurement. First calibrate the scale: 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 then you can place the dumbbell on the scale.
