Symptoms
- Weight varies significantly between consecutive weigh-ins
- Reading seems far off from expected weight
- Scale doesn't turn on or read until stepped on twice
Likely causes
- CommonUneven or soft flooringCarpet or an uneven floor can throw off the scale's load sensors.
- CommonWeak batteriesLow battery power can cause inaccurate or inconsistent sensor readings.
- PossibleScale not calibrated or zeroedSome scales need a calibration step after moving or replacing batteries.
- PossibleApp syncing an old readingBluetooth sync delays can show a previous or averaged reading rather than the current one.
- Less commonSensor damage from being droppedPhysical shock can throw off internal load cell alignment.
What to do
- Move the scale to a hard, flat, level surface like tile or hardwood.
- Replace the batteries with a fresh matched set.
- Step off and back on to let the scale zero itself between uses.
- Check the companion app for a calibration or reset option.
- Weigh yourself twice in a row and compare to check consistency.
- Make sure bare feet are on the metal contact points for body composition readings.
- Contact the manufacturer if readings stay inconsistent on a hard, level floor with fresh batteries.

When to call a pro
If readings remain wildly inconsistent on a hard, level floor with fresh batteries, the internal load sensors are likely damaged and the scale should be replaced.
Safety
Generally low risk
Generally low risk for a careful person. Stop if anything looks different from what this guide describes.
