1) Method  to reduce weight error :


a) This product must be placed on hard and flat ground,such as ceramic tiles and the like,ut it cannot be placed on a carpet and a soft item cannot be padded under the scale.


b) Before each measurement calibration is performed and the method is : You should tread (i.e.,turn on) the scale's LED ,and leave the scale when the displayed number is unstable,

    and the LED will display several letters,i.e.,"CAL",and return to "0".At this time,calibration is completed.


2) Method for decreasing errors of fat percentage and water percentage :


a)This product obtains body fat percentage by using BIA (bio-impedance analysis) bioelectric measurement method.


(I) A surveyor is required to enter correct height/Gender/Age.Once these data are incorrect accurate body fat percentage cannot be obtained.


(II) Bare feet are necessary (socks should be taken off).


(III) In order to ensure that the surveyor obtains the body impedance co-efficient,at time of measurement,please put two feet to cover metal electrodes 

      on left and right sides and keep still till the end of the measurement.The entire measurement process will take about 20 seconds.


(IV)  We suggest performing measurement at the same time  and under the same body condition everyday.

       User should  perform measurement in early morning under condition of fasting;continuous early morning

      fasting  can obtain long term body weight/body fat  percentage change data.
