We recommend always using the same scales in the same conditions, once or twice a week. If possible, weight yourself in the morning, preferably naked, when you are not dehydrated and when you have been to the bathroom.

Every weighing scales is calibrated differently and there can be some differences between the measurement results on two different products. However, if these variations are under +/- 2kg, then the product is not defective. The important thing is always to weigh oneself on the same scales, under the same conditions, one or twice a week in order to track long term changes.

The more precise a weighing scales is, the more sensitive it is. You must always place your scales on a hard and flat surface. During the measurement, try to stay as still as possible. It is perfectly normal to have differences up to 1kg between two measurements on a mechanical scales - this can be explained simply by standing differently on the product. Again, the important thing is to measure long term variations and not the difference between two measurements.

You can set the scales to 0 either by regulating the pointer or the dial (depending on the model) using the re-zero knob situated on the front or back of the scales.

It may be necessary to weigh yourself several times, each time manually regulating the pointer or dial, before the product automatically returns to zero.
