Reasons Why Digital Electronic Scales Is


    There are two possibilities fpr the inaccurate of Digital Electronic Scales:

    ① The body fat scale itself cannot be measured accurately, and the body fat scale should be replaced;

    ②The body fat scale is accurate, but due to its measuring principle, it is affected by other factors during the measurement, so the reading is not accurate.

    The home body fat scale is actually "calculating" the body fat rate

    Whether it is a home body fat scale or a body fat scale used in a gym or a hospital physical examination center, the body fat rate is measured by the bioelectrical impedance method, that is, the "BIA test method."

    There are 4/8 electrode plates on the body fat scale. The body impedance value is measured by the tiny current emitted by the electrode plates, combined with the tester’s height, weight, gender, and age, and a certain algorithm model is used to calculate the body impedance corresponding to the impedance value. Fat rate.

    The main reasons for the error are impedance measurement (temperature change, contact surface moisture content change, body moisture change after exercise, etc. will affect the accuracy of the resistance value), algorithm model (related to the manufacturer's R&D cost).
