Answer

This is most likely due to the scale being stored on its side, moved from one location to another or it is being used on carpet and not on a flat surface. 

In these cases, please make sure the scale is on a flat surface, then wait for about 1 hour so the digital scale can recalibrate. Then step on the scale and take two measurements - the second measurement will be the accurate one as it calibrates after every measurement.
