The Renpho scale has an incremental measurement accuracy range that is based on how much you weigh:
50kgs: ± 0.3kg
100kgs ± 0.4kg
150kgs ± 0.5kg
110lbs: ± 0.66lb
220lbs ± 0.88lb
330lbs ± 1.1lbs
For example, if you weigh 220lbs, the scale is accurate to within ±0.88lbs difference.
Please don’t use the scale if you weigh more than 396 lbs.
