Why is the weighing deviation significant on my Xiaomi MI S400 Scales?
- S
  stevenhumphreyAug 8, 2025
  Significant weighing deviation on your Xiaomi Scales can occur due to several reasons: * Foreign objects or obstructions are present at the scale's feet or edges. * The scale isn't placed on a hard, flat surface. In this case, remove any obstructions, ensure the scale rests on a hard, flat surface, and gently press the four corners to stabilize it before measuring again. * You stepped on the scale before the display showed '0.0 kg'. To fix this, wake up the scale and only measure after '0.0 kg' is displayed. If there's a value showing, wait for it to turn off, then wake the scale and wait for '0.0 kg'.

What to do if Xiaomi MI S400 Scales display '----'?

  If your Xiaomi Scales display '----', it could be due to several reasons: * The scale hasn't been properly bound. Ensure the scale is correctly bound and connected, then troubleshoot using the app's instructions. * You are measuring without stepping on the scale barefoot. Step barefoot on the scale and measure again. * The skin on the soles of your feet is too dry, wet, or scaly, or the scale's electrodes are not clean. Clean both your feet and the electrodes with a slightly damp towel before measuring. * Your feet moved or weren't in contact with the electrodes during measurement. Keep your soles and heels in close contact with the electrodes as much as possible and remain still during measurement.

Why is the body fat measurement deviation significant on my Xiaomi MI S400 Scales?

  Rebecca McclureAug 22, 2025
  Significant deviation in body fat measurement on your Xiaomi Scales can occur due to: * Dry weather or overly dry or wet skin on the soles of your feet. Clean your feet and the scale's electrodes with a slightly damp towel before measuring again. * Feet not fully contacting the electrodes during measurement. Ensure you step barefoot on the scale, keeping your feet in full contact with all four electrodes, and keep your inner thighs, legs, or feet apart. * Measurement taken in an abnormal physical state or after strenuous exercise. Measure again after your body achieves a stable physical state.

  If your Xiaomi Scales won't turn on, it's likely due to a low or insufficient battery level. Replace the batteries and try again.
