At the bottom of the scale you can choose different modes to measure the weight:

In baby mode, the scale takes +/- 10 seconds to determine the correct weight.

This takes account of a moving baby and the scale takes longer to determine the weight. This is then of course very accurate.

When you remove the baby from the scale, the measured weight remains until the display turns off (after 3 seconds).

In office mode, the scale measures the weight directly and does not take into account differences in pressure caused by a moving baby.

Therefore, you will constantly see the weight fluctuate here.

When you take the baby off the scale, the weight immediately returns to 0 until the display is off (after 3 seconds).

This mode has no stabilization function.
