Electronic scale is based on the change of current and voltage to calculate the load weight, electronic scale tray under the pressure sensitive chip, people stand up, the resistance of the pressure sensitive chip will change with the weight, when the current is stable, the electronic scale will show the calculated weight of your. Because it is calculated through the program, it is normal to have a certain difference with the actual weight.
When the electronic scale is just turned on, the current is not stable, and the deviation between the measured results and the actual value will be relatively large, and the results of the second measurement should be closer to the actual weight
