1, simple, if it is out of power, charge or change the battery
2, if there is a problem with the control chip or the sensor probe, first see whether the probe is moved, whether the line is faulty, and then check whether the power supply is normal.
3, if the above is not the sensor may be broken, because the sensor of the electronic scale is a strain gauge attached to the aluminum alloy bracket. The strain gauge paste is more troublesome;
4, finally say: the electronic scale is a measurement product, even if it is repaired, it needs to be re-measured, and the measurement needs to cost; So I suggest a new one.
