If you are getting abnormal measurement results with your Philips body analysis scale (too high, low or a large difference between measurements), follow these steps:
1) Step on the scale barefoot and stand still.
2) Place the device on a flat, hard surface or attach the supplied carpet feet to the feet of the scale when using the device on carpet.
3) Wipe your feet with a damp cloth to make sure that they are damp when you perform the measurement.
Please do not move the scale shortly before measuring or in between measurements. If you do, please wait 5 seconds so the scale can recalibrate.
