My scale shows an unrealistically low weight when I stand on it, why is that? Verified

For the best result, the scale should be standing on a hard level surface. When the scale is standing on for example a rug this can influence the measurement.

Lo means the battery is low and needs to be replaced. If there are batteries inside, they must be charged as soon as possible. Batteries don't like being left empty. Then they break. Batteries last the longest when you keep their charge between 32% and 84% and charge them slowly. (This also applies to smartphones).
